I transform the images contained in the UIImage array into gifs and save them in the simulator's files. How can I save it on the phone's gallery instead?
extension UIImage {
static func animatedGif(from images: [UIImage]) {
let fileProperties: CFDictionary = [kCGImagePropertyGIFDictionary as String: [kCGImagePropertyGIFLoopCount as String: 0]] as CFDictionary
let frameProperties: CFDictionary = [kCGImagePropertyGIFDictionary as String: [(kCGImagePropertyGIFDelayTime as String): 1.0]] as CFDictionary
let documentsDirectoryURL: URL? = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
let fileURL: URL? = documentsDirectoryURL?.appendingPathComponent("animated.gif")
if let url = fileURL as CFURL? {
if let destination = CGImageDestinationCreateWithURL(url, kUTTypeGIF, images.count, nil) {
CGImageDestinationSetProperties(destination, fileProperties)
for image in images {
if let cgImage = image.cgImage {
CGImageDestinationAddImage(destination, cgImage, frameProperties)
}
}
if !CGImageDestinationFinalize(destination) {
print("Failed to finalize the image destination")
}
print("Url = \(fileURL)")
}
}
}
}
override func viewDidLoad() {
super.viewDidLoad()
UIImage.animatedGif(from: [UIImage(imageLiteralResourceName: "secilmemisstep"), UIImage(imageLiteralResourceName: "secilmisstep"), UIImage(imageLiteralResourceName: "secilmemisstep")])
}

Use UIImageWriteToSavedPhotosAlbum().
