SwiftyFORM is a lightweight iOS framework for creating forms
Because form code is hard to write, hard to read, hard to reason about. Has a slow turn around time. Is painful to maintain.
- iOS 12+
- Xcode 12+
- Swift 5.1+
- Several form items, such as textfield, buttons, sliders
- Some form items can expand/collapse, such as datepicker, pickerview
- You can create your own custom form items
- Align textfields across multiple rows
- Form validation rule engine
- Shows with red text where there are problems with validation
- Strongly Typed
- Pure Swift
- No 3rd party dependencies

}With Swift Package Manager support in the latest Xcode, installation has never been easier.
Open your Xcode project -> File -> Swift Packages -> Add Package Dependency...
Search for SwiftyFORM and specify the version you want. The latest tagged release is usually a good idea.
To integrate SwiftyFORM into your Xcode project using CocoaPods, specify the following in your Podfile:
source 'https://github.com/CocoaPods/Specs.git'
swift_version = '5.0'
platform :ios, '12.0'
use_frameworks!
target 'MyApp' do
pod 'SwiftyFORM', '~> 1.8'
endThen, run the following command:
$ pod installLink to demo project that shows a minimal SwiftyFORM app using Carthage.
To integrate SwiftyFORM into your Xcode project using Carthage, specify it in your Cartfile:
github "neoneye/SwiftyFORM" ~> 1.8
Then, run the following command:
$ carthage updateFinally, add SwiftyFORM.framework (will be built by Carthage under Carthage/Build/iOS/) to your project's Linked Frameworks and Libraries in the General tab, and add a new Run Script Build Phase:
- Set
/bin/bashas the shell - write
/usr/local/bin/carthage copy-frameworksin the script body - add
$(SRCROOT)/Carthage/Build/iOS/SwiftyFORM.frameworkto the input files
-
Open up Terminal application and cd into your iOS project directory
-
ONLY IF your project is not already initialized as a git repository, run
$ git init
- Add
SwiftyFORMas a submodule by running
$ git submodule add https://github.com/neoneye/SwiftyFORM.git
-
In the Project Navigator, select your application project and go to "Targets" -> "General"
-
Open the project folder and drag the
SwiftyFORM.xcodeprojfile into the "Frameworks, Libraries, and Embedded Content" tab of your application. -
Click the
+button under the "Frameworks, Libraries, and Embedded Content" section andAddtheSwiftyFORM.framework
