I am trying to implement the ability to save a photo to the user’s photo library on macOS. When I call PHPhotoLibrary.requestAuthorization(for: .addOnly) I just get a .denied status. The user is not prompted for access. I tried adding these entitlements: com.apple.security.personal-information.photos-library, com.apple.security.assets.pictures.read-write. I tried turning off sandboxing entirely. I tried saving despite getting the authorization denied, but unsurprisingly that gives me this error: Domain=PHPhotosErrorDomain Code=3311 I can almost do what i want with NSSharingService(named: .addToIPhoto), but that has the side effect of launching Photos. Is there a trick to getting PHPhotoLibrary.requestAuthorization(for: .addOnly) to work? Thanks. John

I want a widget to use the same custom fonts that the containing app uses. I do not want multiple copies of the font files in the app bundle. I put the font files into a framework shared by the app and the widget extension. I have code to register the fonts from the framework bundle using CTFontManagerRegisterGraphicsFont. That works from the app, but it does not work from the widget extension because it requires UIKit. (At least I think that's why it doesn't seem to work from my widget extension.) Widgets cannot run UIKit code. Is there a way to programmatically register the fonts in a widget? If not is there a way I can make a UIAppFonts Info.plist entry point to a framework?

I am trying to resolve this issue when uploading a Mac app with a share menu extension to App Store Connect: Invalid Provisioning Profile. The provisioning profile included in the bundle com.goldenhillsoftware.Unread2.SubscribeInUnreadExtension [com.goldenhillsoftware.Unread2.pkg/Payload/submitmac.app/Contents/PlugIns/ShareExtension.appex] is invalid. [Invalid 'com.apple.application-identifier' entitlement value.] For more information, visit the macOS Developer Portal. (ID: 01a4a823-62e9-4278-b3b5-46266b168a65) I understand that it wants a com.apple.application-identifier entitlement, but I do not understand how to provide that entitlement. I have tried putting it in the .entitlements file, but that has not worked. Is there a place where I can specify the com.apple.application-identifier entitlement associated with the App ID or when manually generating an entitlements file from the Developer Portal? I don't see it in the list of App Services associated with an App ID in the developer portal. I have seen other threads where folks seem to get past this by deleting currently downloaded provisioning profiles and using Automatically manage signing, but I have not had success with that either. Am I right that the value should be (TeamId).com.company.(AppName)? Should the entitlement include the extension itself ((TeamId).com.company.(AppName).(ExtensionName))? Thanks. John

I have a List that can contain TextField views on macOS. I want tabbing between the TextField views inside the List to work the way it does with TextField views that are not inside a List. But pressing the tab key to navigate to a TextField inside a List just does not seem to work. I tried attaching a focusable(false) modifier to the List and a focusable(true) modifier to the TextField views. Is there a trick to this? var body: some View { TextField("Title:", text: $title, prompt: Text("Title")) List { TextField("Title 2:", text: $title2, prompt: Text("Title 2")) TextField("Title 3:", text: $title3, prompt: Text("Title 3")) } }

When I compile my app with Xcode 14, the app fails to open share sheets. The app just hangs on the call to present( the UIActivityViewController, and eventually crashes with a memory error. I do not see this behavior when I compile with Xcode 13.4, or if I run the app on an iOS 15 device. It is just when compiled with Xcode 14 and run on an iOS 16 device. I tried creating a dedicated view controller with nothing other than a button letting the user present a share sheet. I stripped out everything in the view controller and app delegate other than what is needed to show that view controller. I still see the behavior. But I do not see this when I create a standalone app. I am looking for differences in build settings and Info.plist that might trigger this. Is there something else I should look for? This is the main thread while the app is hung, before it just crashes: Thread 1 Queue : com.apple.main-thread (serial) #0 0x000000019f4f0378 in -[UIButtonLegacyVisualProvider updateConstraints] () #1

I need to detect right-clicks / two-finger clicks with a trackpad or mouse on an iPad inside an action extension. I am finding that if I put a UITapGestureRecognizer in a view controller inside an action extension and set its allowedTouchTypes to UITouch.TouchType.indirectPointer, the gesture recognizer does not fire and none of the UIGestureRecognizerDelegate methods are ever called. The same code inside a standalone app works, just not in an action extension. This happens on both iPadOS 15.5 and iPadOS 16. I can filed FB10296917 regarding this, but it seems odd enough that I wanted to ask here whether I might be missing something.

Is there anything to watch out for or any steps one should take with regard to iCloud Backup and data in SQLite files? I am nervous about the fact that my sqlite databases each have a .sqlite file, a .sqlite-shm file, and a .sqlite-wal file – and wondering whether iCloud backup could end up restoring different versions of these files.

I am experimenting with Sign in with Apple and I have a few questions: First, regarding initial login: An ASAuthorizationAppleIDCredential includes both an authorizationCode so that the server can perform validation, and an identityToken with a signed JWT. If my server uses the authorizationCode to get credential information from appleid.apple.com, can I safely ignore the identityToken returned to the ASAuthorizationControllerDelegate? Or is there a reason I should verify that as well. If I do not verify the identityToken should I still set a nonce on the ASAuthorizationAppleIDRequest? Second, regarding notifications of Apple ID changes: It seems like getCredentialState, server-side token requests based on refresh tokens, and Server to Server notifications all serve the purpose of letting an app find out about changes to an Apple ID. Do I need to implement all three of these, or should any one be sufficient? Finally, I am not sure I need to know about Apple ID changes at all. Can I ignore all of these, and not worry about Apple ID status changes for users already logged into a device? I do not use the account name or email address at all, just the user identifier. Thanks. John

I am looking for a way to apply custom fonts and colors to context menus. I was able to change UIAction text color with the appearance manager:[[[UILabel class] appearanceWhenContainedInInstancesOfClasses:@[NSClassFromString(@"_UIContextMenuActionView")]] setTextColor:[UIColor greenColor]];But doing the same with the font does not work for me:[[[UILabel class] appearanceWhenContainedInInstancesOfClasses:@[NSClassFromString(@"_UIContextMenuActionView")]] setFont:[UIFont systemFontOfSize:30]];Similarly I cannot find a way to apply custom colors to the separator lines between UIActions or inline UIMenus.Is there a way to do this?Thanks.John

I am running into a weird bug where videos embedded in WKWebViews do not appear. I get audio, but the screen goes black. A few notes: This happens on iOS 15 and the 15.1 beta, but not iOS 14.8. I have three WKWebViews in the view hierarchy. If I reduce the number of WebViews to one, I do not encounter this issue. When I encounter this issue with one WebView, playing the same video from another WebView will work. It seems to happen more often when in dark mode than in light mode. This might be an Apple bug, but I have not been successful in building a standalone app that can reproduce this.I know this isn’t a lot to go on, but if anyone has pointers or can suggest something to try I would appreciate it. Thanks. John

In earlier iPadOS betas I used the globe-Q keyboard shortcut to create a Quick Note. This no longer works for me, and I am not sure why. I do not see the keyboard shortcut listed if I hold down the globe key. Was the keyboard shortcut removed? Could the problem be that I have a Magic Keyboard (not designed specifically for an iPad) and have the function key mapped to the globe key? John

I have code to create a new window with UIApplication.shared.requestSceneSessionActivation. I now want that window to have the prominent presentation style (UIWindowScenePresentationStyleProminent) on iPadOS 15. But it is not clear to me how to get that presentation style when using requestSceneSessionActivation. What am I missing?

I have been having trouble submitting my app to App Store Connect after building it with Xcode 13. I figured out that if a project contains this Objective-C code, App Store Connect will reject the app claiming it to use NSConstantDictionary as a private API: NSDictionary *myDictionary = @{@"a":@"b", @"c":@"d" }; NSLog(@"myDictionary: %@", myDictionary); I suspect the same issue exists for NSArray, at least when written with @[@"a", @"b"] notation. I filed FB9188387 regarding this. It seems like a pretty big problem. The FB includes a very simple sample project that gets rejected with the error above. The same project archived and submitted by Xcode 12.5 is accepted. The FB also contains a copy of this sample project with the two lines above commented out. That is accepted and processed by App Store Connect. John

I understand that I cannot display attributed strings in SwiftUI, and therefore that I cannot display them in widgets. Am I right that there is also no ability to use Core Text to display formatted strings in widgets? It looks to me like my options for displaying text in widgets are Text views and images generated by my app. I just want to confirm that this is the case. Thanks.

Is there a way to calculate what the height of a VStack of Text views would be if added to a view, but to do so without necessarily adding it? I am trying to figure out if I need to use NSAttributedString code to calculate formatted string heights. Thanks. John
