This looks like a refresh of an old question. I'm using iOS 15 beta 7 and have presented a UIActivityViewController from a SwiftUI app. I get a ton of these errors when trying to share a two-item list containing String and UISimpleTextPrintFormatter. [default] LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]} [default] Attempt to map database failed: permission was denied. This attempt will not be retried. [db] Failed to initialize client context with error Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]} [default] -imageForImageDescriptor: can do IO please adopt -imageForDescriptor: for IO free drawing or -prepareImageForDescriptor: if IO is allowed. (This will become a fault soon.) [default] LaunchServices: store (null) or url (null) was nil: Error Domain=NSOSStatusErrorDomain Code=-54 "process may not map database" UserInfo={NSDebugDescription=process may not map database, _LSLine=264, _LSFunction=-[_LSDReadClient getServerStoreWithCompletionHandler:]} It looks as if the API is checking for entitlements I haven't requested, but I am not trying to share images. I just want to share text as plaintext or a nicely formatted printable attributed string.

I have several views I want to animate in concert. I plan to use keyframe animation. I want to keep the .keyFrameAnimator modifier code small; I have a lot of ...Keyframes inside several KeyframeTracks. It seems like I should be able to isolate the body of the keyframes parameter into a func or var. Builders are such a pain, I can't grok the right way to refactor their bodies out. I've tried to make a standalone @KeyframeTrackContentBuilder<MyValue> function but cannot figure out the right syntax/incantation to stuff it with KeyframeTracks. My latest attempt is to create a func that returns a KeyframeTimeline, but that's been a deadend too. let k: KeyframeTimeline<MyValue> = timeline(...) CartoonCardView(color: .yellow) .keyframeAnimator( initialValue: k.value(time: 0) ) { content, value in content .rotationEffect(value.angle) .scaleEffect(value.scale) .offset(value.offset) } keyframes: { _ in k } The error on k in the last line is "No exact matches in call to static method 'buildExpression'" with the sub-error "Candidate requires that 'KeyframeTimeline' conform to 'KeyframeTrackContent' (requirement specified as 'K' : 'KeyframeTrackContent') (SwiftUICore.KeyframesBuilder)"

.modelContainer(for: MyMode.self, isUndoEnabled: true) This may work for single model containers, but I have a number of models. I don't see how to enable undo for multiple model containers.
