Catalina 10.15.7 same issue still not fixed, it's actually way worst. Unbelievable. User @raymo is actually correct, switching the iOS Simulator, if you are a developer, fixes it for a bit.

I have the latest macbook pro, with top specs, average/big sized project, the whole machine or xcode were freezing or lagging heavily until i updated every updatable thing (OS, tools, etc) and restarted several times. Now it works fine, but the editor still lags heavily for trivial operations, like editing function documentation. Surprise surprise, once another non properly QAed version of xcode for us.

A trillion dollar company and after 6 years still loosing days on this stupid problem. This is disgusting. I am speechless.

The same issue has existed when using cocoapods for a long time as far as i can tell, the workaround (since Apple never bothered fixing it) was to have a post-install fix/script in the Podfile that overwrote the target version for each pod. If the issue persist in the next versions (Xcode 13.3 still has it) maybe we could make something alike for SPM.

Xcode 13.3, same issues, i removed all the embedded frameworks and re-added them, and it worked.

Same problem here with Beta 5 too.

Same here. Edit: found the solution, see https://stackoverflow.com/questions/65174463/deploying-iphone-and-ipad-apps-on-apple-silicon-macs-from-testflight

Converting to .tabViewStyle(.page) also breaks inner Navigation Bars or at least Safe Area for me. It would require a severe rewrite of the whole app UI structure. iOS 17.5 beta is out and no fix for this. How is it possible SwiftUI cannot be a reliable tool after this much time.

I have the same problem. I get the two lines in the Logs and then an EXC_BREAKPOINT. [ERROR] Could not create a bookmark: NSError: Cocoa 4097 "connection to service named com.apple.FileProvider" updateImageHeadroom:1309: *** ERROR: CGImageSetHeadroom: 8.000000 failed for image with kCGColorSpaceDisplayP3 color space Breakpoints do not work most of the times with async code. And this is the only thing i get from the Stack trace: CoreTransferable`(1) await resume partial function for reabstraction thunk helper <τ_0_0, τ_0_1, τ_0_2 where τ_0_0: CoreTransferable.Transferable, τ_0_0: Swift.Decodable, τ_0_0: Swift.Encodable, τ_0_1: Combine.TopLevelEncoder, τ_0_2: Combine.TopLevelDecoder, τ_0_1.Output == Foundation.Data, τ_0_2.Input == Foundation.Data> from @escaping @callee_guaranteed @Sendable @async (@guaranteed Foundation.Data) -> (@out τ_0_0, @error @owned Swift.Error) to @escaping @callee_guaranteed @Sendable @async (@in_guaranteed Foundation.Data) -> (@out τ_0_0, @error @owned Swift.Error): Xcode16.0, Swift6

XCode 16.0, iOS 18 and still experiencing the same issue. Confirmed being the Annotation the problem
