An image gallery for iOS
RIGImageGallery is a photo gallery meant to provide most of the functionality of the image gallery in the system Photos app, and handle asynchronous loading of images.
This library is part of the Raizlabs Interface Guidelines, which are UI components that offer sensible defaults to help a project get off the ground quickly with components that feel native to the platform, and with easy to use customization options.

func createPhotoGallery() -> RIGImageGalleryViewController {
let urls: [URL] = [
"https://placehold.it/1920x1080",
"https://placehold.it/1080x1920",
"https://placehold.it/350x150",
"https://placehold.it/150x350",
].flatMap(URL.init(string:))
let rigItems = urls.map { _ in
RIGImageGalleryItem(placeholderImage: UIImage(named: "placeholder"))
}
let rigController = RIGImageGalleryViewController(images: rigItems)
for (index, URL) in urls.enumerated() {
let request = imageSession.dataTask(with: URLRequest(url: URL)) { [weak rigController] data, _, error in
if let image = data.flatMap(UIImage.init), error == nil {
rigController?.images[index].image = image
}
}
request.resume()
}
return rigController
}
