I am trying to recreate the iOS Messages app photo selection UI, where a PHPickerViewController is displayed half screen, with the message text field and a scrolling photo viewer on top. I have that UI mostly working, but cannot figure out how to allow a user to remove an image from my scrolling photo viewer (just like in the iOS Messages app). When the picker is initially displayed, I can show selected images using the preselectedAssetIdentifiers. However, if the user taps the "x" to remove an image from the scrolling photo viewer, there is no way that I have found to update that selection in the picker. I can dismiss/show a new picker with the animated property set to false, but that creates a very apparent bounce in the screen. Are there any ways I am missing to accomplish this? Here is what I have so far:

Is there a suitable UTType type to satisfy the need to pick up only SpatialVideo in UIDocumentPickerViewController? I already know that PHPickerFilter in PHPickerViewController can do this, but not in UIDocumentPickerViewController. Our app needs to adapt both of these ways to pick spatial videos So is there anything that I can try in UIDocumentPickerViewController to fulfill such picker functionality?

I'm getting the following error in my SwiftUI code: "Main actor-isolated property 'avatarImage' can not be referenced from a Sendable closure" I don't understand how to fix it. This happens in the following code: You can copy-paste this into an empty project and make sure to have Swift 6 enabled under the Build Settings > Swift Language Version import PhotosUI import SwiftUI public struct ContentView: View { @State private var avatarItem: PhotosPickerItem? @State private var avatarImage: Image? @State private var avatarData: Data? public var body: some View { VStack(spacing: 30) { VStack(alignment: .center) { PhotosPicker(selection: $avatarItem, matching: .images) { if let avatarImage { avatarImage .resizable() .aspectRatio(contentMode: .fill) .frame(width: 100, height: 100) .foregroundColor(.gray) .background(.white) .clipShape(Circle()) .opacity(0.75) .overlay { Image(systemName: "pencil") .font(.title) .shadow(radius: 5) } } else { Image(systemName: "person.circle.fill") .resizable() .aspectRatio(contentMode: .fit) .frame(width: 100, height: 100) .foregroundColor(.gray) .background(.white) .clipShape(Circle()) .opacity(0.75) .overlay { Image(systemName: "pencil") .font(.title) .shadow(radius: 5) } } } } } .onChange(of: avatarItem) { Task { if let data = try? await avatarItem?.loadTransferable( type: Data.self ) { if let processed = processImage(data: data) { avatarImage = processed.image avatarData = processed.data } else { } } } } } private func processImage(data: Data) -> (image: Image?, data: Data?)? { guard let uiImage = UIImage(data: data)?.preparingForDisplay() else { return nil } // Check original size let sizeInMB = Double(data.count) / (1024 * 1024) // If image is larger than 1MB, compress it if sizeInMB > 1.0 { guard let compressedData = uiImage.compress() else { return nil } return (Image(uiImage: uiImage), compressedData) } return (Image(uiImage: uiImage), data) } } #Preview { ContentView() } public extension UIImage { func compress(to maxSizeInMB: Double = 1.0) -> Data? { let maxSizeInBytes = Int( maxSizeInMB * 1024 * 1024 ) // Convert MB to bytes var compression: CGFloat = 1.0 let step: CGFloat = 0.1 var imageData = jpegData(compressionQuality: compression) while (imageData?.count ?? 0) > maxSizeInBytes, compression > 0 { compression -= step imageData = jpegData(compressionQuality: compression) } return imageData } }

When picking a photo in the gallery, whatever the orientation of the original image, size is always as landscape if let image = info[convertFromUIImagePickerControllerInfoKey(UIImagePickerController.InfoKey.editedImage)] as? UIImage { print("picked original", image.size) For a portrait photo: picked original (1122.0, 932.0) For a landscape: picked original (1124.0, 844.0) What am I missing ?

I am on Xcode 16.2 and running a simulator for iOS 18.2. Previously, I was on Xcode 15.x and running iOS 17.4 sims. This problem did not occur for me on iOS 17.4. Sample code is as follows: import SwiftUI import PhotosUI struct ContentView: View { @StateObject var imagePicker2 = ImagePicker() var body: some View { ScrollView { VStack { Image(systemName: "globe") .imageScale(.large) .foregroundStyle(.tint) Text("Hello, world!") .background(Color.orange) .padding(.bottom, 75) PhotosPicker(selection: $imagePicker2.imageSelection, matching: .images, photoLibrary: .shared()) { Label("", systemImage: "photo") } .font(.system(size: 55)) .padding(.bottom, 55) if let image = imagePicker2.image { HStack { image .resizable() .frame(width:75, height:75) .scaledToFit() .overlay(Rectangle().stroke(Color.teal, lineWidth: 2)) } } } .padding() } } } import SwiftUI import PhotosUI @MainActor class ImagePicker: ObservableObject { @Published var unableToLoad: Bool = false @Published var image: Image? @Published var myUIImage: UIImage? @Published var imageSelection: PhotosPickerItem? { didSet { unableToLoad = false if let imageSelection { //.. try to convert photosPickerItem imageSelection into a uiImage Task { try await setImage(from: imageSelection) } } } } func setImage(from imageSelection: PhotosPickerItem?) async throws { do { if let data = try await imageSelection?.loadTransferable(type: Data.self) { print("got image data") if let uiImage = UIImage(data: data) { print("converted to uiImage") self.image = Image(uiImage: uiImage) self.myUIImage = uiImage } } } catch { print(error.localizedDescription) unableToLoad = true } } } The image loads on the UI but I get "[ERROR] Could not create a bookmark: NSError: Cocoa 4097 "connection to service named com.apple.FileProvider" in the log every time I choose a new photo. So far, I haven't had an actual crash but others have indicated that depending on what they're doing code-wise, that some have crashed. Is this an iOS 18.x bug? Thoughts?

I'm currently trying to add support for Image Playground to our apps. It seems that it's not working in an app that is "Designed for iPad" and runs on a Mac. The modal just shows a spinner and the following is logged to console: Private sandbox for com.apple.GenerativePlaygroundApp.remoteUIExtension : <none> Private sandbox for com.apple.GenerativePlaygroundApp.remoteUIExtension : <none> Private sandbox for com.apple.GenerativePlaygroundApp.remoteUIExtension : <none> Private sandbox for com.apple.GenerativePlaygroundApp.remoteUIExtension : <none> GP extension could not be loaded: Extension (platform: 2) could not be found (in update) dealloc Query controller [C32BA176-6A3E-465D-B3C5-0F8D91068B89] ImagePlaygroundViewController.isAvailable returns true, however. In a "real" Mac Catalyst app, it's working. Just not when the app is actually an iPad app. Is this a bug?

I have an app that edits photos in your library. When I call try CIContext().writeHEIFRepresentation(of: editedImage, to: fileURL, format: .RGBA8, colorSpace: originalImage.colorSpace!) The following is logged to the console: writeImageAtIndex:1012: ⭕️ ERROR: 'App' is trying to save an opaque image (5712x4284) with 'AlphaLast'. This would unnecessarily increase the file size and will double (!!!) the required memory when decoding the image --> ignoring alpha. What does that mean and how can I resolve it?
