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 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

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
