An exhaustive expansion of the standard SwiftUI library.

SwiftUIX

SwiftUIX attempts to fill the gaps of SwiftUI, providing an extensive suite of components, extensions and utilities to complement the standard library. This project is by far the most complete port of missing UIKit/AppKit functionality, striving to deliver it in the most Apple-like fashion possible.

Why

The goal of this project is to complement the SwiftUI standard library, offering hundreds of extensions and views that empower you, the developer, to build applications with the ease promised by the revolution that is SwiftUI.

Requirements

Note

Swift 5.9 is the latest release for Swift and adds support for macros, support for Swift 5.8 will be dropped soon.

• Deployment target: iOS 13, macOS 10.15, tvOS 13, watchOS 6 and visionOS 1 beta 6 (Xcode Xcode 15.1 beta 3)
• Xcode 15.0+

Installation

The preferred way of installing SwiftUIX is via the Swift Package Manager.

/// Package.swift
/// ...
dependencies: [
    .package(url: "https://github.com/SwiftUIX/SwiftUIX.git", branch: "master"),
]
/// ...

Xcode 15 integrates with libSwiftPM to provide support for iOS, watchOS, macOS and tvOS platforms.

1. In Xcode, open your project and navigate to File → Swift Packages → Add Package Dependency...
2. Paste the repository URL (https://github.com/SwiftUIX/SwiftUIX) and click Next.
3. For Rules, select Branch (with branch set to master).
4. Click Finish.
5. Open the Project settings, add SwiftUI.framework to the Linked Frameworks and Libraries, set Status to Optional.

Contents

All documentation is available via the repository wiki.

While the project itself is stable and heavily being used in production, its documentation is work-in-progress. Contributions are encouraged and welcomed.

swiftuix's Issues

NavigationBar custom View gesture bug

.navigationBarTitleView(
HStack {
    Text(title)
    Image(systemName: "chevron.down")
}.onTapGesture {
    self.isPopUpPresented = true
}
, displayMode: .inline)

When I click first time on the label, pop-up is presented. Inside pop-up I select the option which changes title state and closes itself, after that title view stops responding to tap gestures.

AttributedText height problems when put in List or ScrollView

This doesn't show anything:

struct ContentView: View {
  var body: some View {
    ScrollView {
      AttributedText("Hello World\nSecond Line")
    }
  }
}

And when you put it in a List instead of a ScrollView, it only shows the first line.

contentOffset doesn't work for CocoaList

Contentoffset works very well under CocoaScrollView.
But it doesn't work under CocoaList.

import SwiftUI
import SwiftUIX

struct CocoaListBugReport: View {
    var listData = (0...300).map{Item(title: String($0))}
    var body: some View {
        CocoaList(listData){ item in
            Text(item.title)
        }
        .contentOffset(.constant(CGPoint(x:0,y:400)))
    }
}

struct CocoaListBugReport_Previews: PreviewProvider {
    static var previews: some View {
        CocoaListBugReport()
    }
}

struct Item: Identifiable {
  var id = UUID()
  var title: String
}

TextView moves cursor to the end after return key

In TextView, pressing return key twice, moves the cursor to the bottom of the TextView. Which makes it unusable. Any ideas how to fix it?

On XCode 11.3.1. In simulator and on device. Try it with this trivial code. Run it and type in: return key, some text, scroll the cursor to the top, return key.

import SwiftUI
import SwiftUIX

struct ContentView: View {
    @State private var text = ""
    
    var body: some View {
            TextView("type in", text: $text)
    }
}

struct ContentView_Previews: PreviewProvider {
    static var previews: some View {
        ContentView()
    }
}

TextView does not respect .font(_:)

Crashed when using isIntialFirstResponder on CocoaTextField

Environment

• master branch
• Xcode11.4 beta4
• CocoaTextField.swift

Problem

Crashed when using isIntialFirstResponder(true) modifier.

eg)

SomeView
.sheet(isPresented: $isPresented) {
    CocoaTextField("", text: self.$text)
        .isInitialFirstResponder(true)
}

Why

Calling becomeFirstResponder() -> Bool may cause crash before adding the view to view hierarchy as described in this apple document.: (https://developer.apple.com/documentation/uikit/uiresponder/1621113-becomefirstresponder)

I suppose SwiftUI doesn't change view hierarchy while it is in makeUIView step. so, Calling becomeFirstResponder() in makeUIView cause crash.

Workaround

Use DispatchQueue.main.async to delay executing becomeFirstResponder(). updateUIView() doesn't occur crash, so I suppose SwiftUI add view to view hierarchy just after makeUIView().

before

public func makeUIView(context: Context) -> UIViewType {
        let uiView = _UITextField()
        
        uiView.delegate = context.coordinator
        
        if let isFirstResponder = isInitialFirstResponder, isFirstResponder {
                uiView.becomeFirstResponder()
        }
        
        return uiView
    }

after

public func makeUIView(context: Context) -> UIViewType {
        let uiView = _UITextField()
        
        uiView.delegate = context.coordinator
        
        if let isFirstResponder = isInitialFirstResponder, isFirstResponder {
            
            DispatchQueue.main.async {
                uiView.becomeFirstResponder()
            }
        }
        
        return uiView
    }

PaginationView and currentPageIndex

Further to my recent PaginationView issue I would like to get the current page number, but can't see a way of achieving this. Is there one?

ImagePicker

It would be nice if you could #add the option to choose the SourceType on the interface rather than hardwire it to .photoLibrary.

BTW You haven't responded to my comment on issue #66 (which you had closed).

Named Color Support

Named colours currently don’t work.

At the line linked below, calling Mirror(reflecting: base).children.first?.value gives the name of the color. It can then be used with UIColor(named: xxx).

https://github.com/SwiftUIX/SwiftUIX/blob/master/Sources/Intermodular/Helpers/AppKit%20or%20UIKit/AppKitOrUIKitColor+.swift#L86

SectionNavigator navigate destination closure called two times

var body: some View { Text("hello world") .onTapGesture { self.isActive = true } .navigate(isActive: $isActive, onDismiss: nil, to: { Text("hello") }) }
Text("hello") closure called two times

[Bug] Not correctly reload button in navigation bar

Hi,
I use your library. Thanks for your work.
I have a problem.
In my app I set the bar ButtonItems like this

NavigationView {
MyView(vM: .init()).navigationBarItems(leading: self.LeadingButton(), center: self.NavbarImage(),
                                                            trailing: self.TrailingButton(), displayMode: .inline)
}

However, sometimes I need to hide/modify the barbuttons I show to the user.
So, there is a @published variable in the model of the Main View that change if the user make specific action.

Here the problem:
the buttons are not update, it still show the old ones.
I try to use the native method of SwiftUI (without center and displayMode) and it works fine the buttons update, so I guess the problem is a missing refresh. What can I do?

No such module 'Merge'

I get this error since trying to update the Swift Package from revision 89d980c4db9c636bed505a3df9e64f4287881777 to 6ac261ace4a5b20bdbe16deebfdacf9fe274329a.

Present sheet with Clear Background

I needed to present a modal sheet with clear background. I'm using now this workaround:

extension UIViewController {
    func present<Content: View>(presentationStyle: UIModalPresentationStyle = .automatic, transitionStyle: UIModalTransitionStyle = .coverVertical, clearBackground: Bool = false, animated flag: Bool = true, completion: @escaping () -> Void = {}, @ViewBuilder builder: () -> Content) {
        let toPresent = UIHostingController(rootView: AnyView(EmptyView()))
        toPresent.modalPresentationStyle = presentationStyle
        toPresent.modalTransitionStyle = transitionStyle
        toPresent.rootView = AnyView(
            builder()
//                .environment(\.viewController, ViewControllerHolder(toPresent))
        )
        if clearBackground  {
            toPresent.view.backgroundColor = .clear
        }
        self.present(toPresent, animated: flag, completion: completion)
    }
}

and using it with:

UIApplication.shared.windows.first?.rootViewController?.present(...)

There is the possibility to implement this like for View+navigate, (View+present)?

AppKit & UIKit Support

Take a look at my implementation, maybe you'll find it useful 😎

Checkbox images

I think it's more intuitive if the checkbox used an empty square image when off ("square" instead of "checkmark.square").

When we have multiple checkboxes and none of them is on, it feels like they're all checked by default.

Can you please update or give us the option to choose which symbol to use?

Cannot contribute to the wiki

This library is great, but not enough documented.
How do I editing document in the Wiki?

Navigating a Page Control

I have used PaginationControl with a ForEach view. I would like to add control buttons to navigate between views. Is this possible, and if it is, how?

[Bug] NavigationBar size at start

Hi,

I have a simple problem: my app when start the navigation bar has the wrong size (expanded and not inline), after a simple refresh the navigationBar change to the correct size, but it is pretty ugly.
If i put an empty navigationTitle the size is correct, but it seems a bit hackish (or maybe is the correct way? I am not very skilled about SwiftUI)
Here a snippet to show what I mean:

MyView(viewModel:.init())
                       .navigationBarTitle("", displayMode: .inline) //need this line to show as inline at start
                       .navigationBarItems(leading: EmptyView(), center: NavbarLogoImage(),
                                                          trailing: EmptyView(), displayMode: .inline)

PaginationView doesn't show

Hi,
it seems that PaginationView doesn't show in the main view where I place it. See a couple of examples of what I tried below.

ScrollView(.vertical) {
        
            VStack(alignment: .leading) {

                ExerciseMediaPaginatedHeader(exercise: self.exercise)
            

                .... other views

}
}

This doesn't show inside the Scroll view above:

struct ExerciseMediaPaginatedHeader: View {

let exercise:Exercise
  
  var body: some View {
    PaginationView(axis: Axis.horizontal) {

        Text("bla")
        Text("blup")
        Text("foo")
    }
  }

}

Pagination view also does not show in the scroll view above if I add more complex views:

struct ExerciseMediaPaginatedHeader: View {

let exercise:Exercise
  
  var body: some View {
    PaginationView(axis: Axis.horizontal) {
        
        self.getViews()
    }
  }

func getViews()->[AnyView] {
    
    var views: [AnyView] = [VideoZStackView(storagePath: self.exercise.videoStoragePath).eraseToAnyView()]
    self.exercise.imageStoragePaths.forEach { (path) in
        let firebaseImageView = FirebaseImage(storagePath: path).frame(width: CGFloat(UIScreen.main.bounds.width  - CGFloat(20)), height: CGFloat(UIScreen.main.bounds.width - 20) / CGFloat(1.78), alignment: .center).aspectRatio(contentMode: .fill).eraseToAnyView()
        views.append(firebaseImageView)
    }
    return views
}

}

When adding more complex views without using the getViews func above , the swift compiler thows some BS SwiftUI-style fake errors that we all love:

  var body: some View {
    PaginationView(axis: Axis.horizontal) {
        
        VideoZStackView(storagePath: self.exercise.videoStoragePath).eraseToAnyView()

        FirebaseImage(storagePath: self.exercise.imageStoragePaths.first!).frame(width: CGFloat(UIScreen.main.bounds.width  - CGFloat(20)), height: CGFloat(UIScreen.main.bounds.width - CGFloat(20)) / CGFloat(1.78), alignment: .center).aspectRatio(contentMode: .fill).eraseToAnyView()

// 'fake' compiler error: "Binary operator / cannot be applied to types Int and Double" . But I used this views within other views before and there was no error.
}
}

thanks for looking into this.

regards
Dominik

TextView Placeholder not dissappearing anymore

The TextView Placeholder text is not disappearing anymore when entering text in the field.

SwitchOver with associated values?

Is it possible? Can't find any documentation.

PaginationView index

Hi, great library!
Currently when updating the PaginationView index programmatically with currentPageIndex the page control dots don't change and also get out of sync with the index if you switch to swiping

Can't load dynamic data inside PaginationView

I have to display some data from api. This is the code:

PaginationView(axis: .horizontal) {

                ForEach(self.banners, id: \.id) { item in
               
URLImage(URL(string:"exampleurl")!)
                    { proxy in
                        proxy.image
                            .resizable()
                    }.frame(width: UIScreen.main.bounds.width - 120, height: 200).aspectRatio(contentMode: .fit)
                        .cornerRadius(15)

                }
                
            }.onAppear(perform: loadData)

Everything I put inside foreach, even if I put static data it says Cannot convert value of type 'ForEach<[Banner], Int, some View>' to closure result type 'Array'.
How can I load data with foreach inside PaginationView?

What is the need of @State private var isPresented?

In PresentationLink.swift, what is the use of @State private var isPresented? It is never read.
It is never used.

public struct PresentationLink<Destination: View, Label: View>: View {
    public let destination: Destination
    public let label: Label

    private let onDismiss: (() -> ())?

    public init(destination: Destination, onDismiss: (() -> ())? = nil, @ViewBuilder label: () -> Label) {
        self.destination = destination
        self.label = label()
        self.onDismiss = onDismiss
    }

    public var body: some View {
    Button(action: nil, label: { label })
    .sheet(
    onDismiss: dismiss,
    content: { self.destination }
    )
    }

    private func dismiss() {
        onDismiss?()
    }
}

[Question] How to set large title view?

I tried to use navigationBarTitleView(_: displayMode) to add a

NavigationView {
                List(emojiList, id: \.self) {
                    Text($0)
                }.navigationBarTitleView(
                    VStack {
                        Text("My Title")
                        Text("My sub-title").font(.subheadline)
                    }.height(84).width(200),
                    displayMode: .large
                )
            }.tabItem {
                Image(systemName: "star")
            }

However, it seems that the LargeTitle is not set, and only the view in the centre is set, which would be the behaviour after the user had scrolled -- so the large title would be collapsed.

Is there a way of setting a large title view that will collapse?

It would be helpful to provide some kind of sample app or even more usage examples for your supplied UIX components. Looking forward to get to know how to use PaginationViews properly.

XCode 11.5 Archive Issue

Create docs branch so I can open a PR? =D

Hi, I thought the project would eventually need a docs page if it continues to grow (as opposed to having a giant README hehe), so I started one.

However, I don't have anywhere to create a PR to (I used a new docs branch). Could you create this empty branch so I can send a PR? =)

TextView does not expose .foregroundColor(_:)

More Documentation/Example usage

Great library. I know it's work in progress but would love to see more documentation and example usage of components.

Keep up the good work.

Add alias for systemGray and systemGray2-6

Activity Indicator Crash

On iOS 13.0 I’m getting a crash:
Fatal error: Reading Environment<Optional> outside View.body: file
When accessing the uiView.color = tintColor?.toUIColor()

On iOS 13.1+, no crash is caused.

A workaround could be to disable tint color on iOS 13.0 only?

Setting CocoaList's contentOffset

I'd like to save the scroll offset of a CocoaList while navigating through pages.

I thought it was possible by using the onOffsetChange modifier, but the exposed ScrollView<AnyView>.ContentOffset argument doesn't let you get the contentOffset property as it seems to be declared as fileprivate.
I've tried creating a extension CocoaList with a custom method to get it, but the compiler tells me that the property is set as internal.

Also, I'd like to set the contentOffset back to where it was after navigating towards a page, but it seems there is no public setContentOffset: there's one in UIHostingTableViewController, but it isn't accessible.

Is there a way to currently do the things above?

Thanks in advance for any clarification.

TextView holding reference to NSView

Hi - great module; thanks for it! :)

I'm running into a weird issue with TextView running on macOS on a master/detail view: When there's a TextView in the detail view, the contents of the TextView continue to show (and edit) the first item selected in the list view, even though the rest of the detail view has changed.

Gif of the issue: https://www.dropbox.com/s/2cp6upj7twfi601/TextView.gif

To set up to reproduce:

• Make a new project in Xcode, e.g. "TextViewTest", selecting macOS > App and checking the box to use SwiftUI. Deselect Core Data, CloudKit, tests, etc.
• Go to File > Swift Packages > Add Package Dependency and add SwiftUIX
• Copy/Paste the code below to replace what's in ContentView.swift

To reproduce:

• Build and run the app
• Click on one of the items in the list on the left
• Enter a note on the right
• Click on one of the other items in the list of the left

Expected result:

• The detail on the right should update to show the new selection's name (e.g. "Fish") and the placeholder text to enter a new note

Actual result:

• The detail on the right updates the name, but the previously entered note remains.

Notes:

• The note is still editing the note property of the original object.
• If you click outside of one of the options (that is, select no option), then click an option again, TextView shows that option's note field (and will persist to until you select nothing again).
• I'm not working on a meal selection app, I'm just hungry. ;-)

    struct ContentView: View {
        @State var selection: UUID?

        var meals = [

            Meal(name: "Steak"),
            Meal(name: "Chicken")
        ]

        var selectedMeal: Meal? {
            meals.first(where: {$0.id == selection})
        }

        var body: some View {
            HStack {
                List(selection: $selection) {
                    ForEach(meals) { meal in
                        Text(meal.name).tag(meal.id)
                    }
                }

ObservedPublisher for CurrentValueSubject

ObservedPublisher is a great solution that combines @State and onRecevie into one. But when using CurrentValueSubject there is a problem, ObservedPublisher ignores dropping the first value.
I added a line to the code and now it adapts nicely to CurrentValueSubject.

self._subscription = .init(initialValue: publisher
       .delay(for: .nanoseconds(1), scheduler: RunLoop.main)
       .sink(receiveValue: {
            updateWrappedValue.value($0)
        }))

CocoaTextField Bug

CocoaTextField(text: $text, label: {Text("name:")})
        .placeholder("hello")

after using .placeholder , the app will crush.

And I have another question, how do I change the color of TextField's input text ?
I can't use .foregroundColor(.red) to do it.

Autohide keyboard when tap outside TextField

When tapping outside the TextField, the keyboard should hide automatically.

TextView modifiers don't work as expected

Hi, great library but TextView doesn't work as expected. It seems onCommit is never executed.
The modifier font seems to work but foreground color, keyboard type and line limit don't seem to work either. I don't know how the keyboard can resign either.
Thanks for looking int this.

    TextView("Notes", text: self.$workoutManager.workout.notes, onCommit: {
        /// is never executed. 
         UIApplication.shared.windows[0].endEditing(true)
        
    }).font(.footnote).foregroundColor(.blue).keyboardType(.decimalPad).lineLimit(4)

CocoaList initialContentAlignment issue

I have noticed an issue with current CocoaList initialContentAlignment implementation.
The issue seems to be in UIHostingTableViewController.correctContentOffset function.
This function is called whenever content size is updated by the observe value function in the event a view is added to the data source.
The issue here is the oldContentSize value: observeValue seems to be called multiple times with values like:

1. old: 642 new: 452 (discarded by correctContentOffset: more on that later)
2. old: 452 new: 722 (accepted by correctContentOffset)

You seem to have noticed this in correctContentOffset:

guard oldContentSize.maximumDimensionLength < newContentSize.maximumDimensionLength else {
    return
}

You then calculate the offset like this:

if initialContentAlignment.vertical == .bottom {
      newContentOffset.y += newContentSize.height - oldContentSize.height
}

but the delta is way higher than it should be (722-452 instead of 722-642) resulting in a wrong content offset.

If you remove the said guard the delta would be correct, but the offset will be set even when tableView.frame.size.height < newContentSize.height causing the view to be scrolled to bottom even when the content is not filling the whole frame.
You can't even guard on that condition because the condition could match the second call from observeValue and not the first one.

I'm new to UIKit and I have no idea why it's behaving like that.
I'm looking forward to hear your opinion on that.
Thanks.

PaginationView set currentPageIndex

Hello, I have a Binding like this: .currentPageIndex(self.$currentImageIndex)

When I set a new value for the currentImageIndex, the PaginationView changes to the correct page, but the pagination dots don't change.
Do I need to keep them in sync manually or is it a possible bug?

Build errors in watchOS and tvOS

watchOS
This error came up where you were calling an extension to AppKitOrUIKitHostingControllerProtocol. I noticed that most of the file is hidden from watchOS, except for this extension, though. You can probably solve this by hiding the extension from watchOS.

#if !os(watchOS) // Add this
extension AppKitOrUIKitHostingControllerProtocol {
    // ...
}
#endif // And this

tvOS
This one came up at if base?.isPagingEnabled ?? false (Under _UIHostingScrollViewRootView).

Navigation Bar size

PaginationView & ProgressionController

Following your suggestion in #66 I have tried using prevButton etc within a PaginationView content with @Environment(.progressionController) var progressionController. When the code is executed the progessionController value is nil. I can see that it is set privately in the controller code, but it doesn't seem to expose it publicly. What am I missing?

PaginationView PageControl not showing when alignment is set to .horizontal

There is an issue inside PaginationView.init where it is always ignoring the passed pageIndicatorAlignment argument (assuming it is always nil is wrong). Also I don't understand this check if axis == .vertical || pageIndicatorAlignment != .center { ... } inside PaginationView.body. The PageControl isn't showing when the alignment is horizontal. The check has to be removed and the paddings have to be corrected to account for all pageIndicatorAlignment cases.

PaginationView auto height

Is there a way to detect the height of the tallest view inside the PaginationView and make it its frame height?
Also, is it possible to make an "Auto Play" so it behaves like a slideshow?
