Unfortuantly no cant post here, removing just the problem classes to a seperate project compiles fine.

Thanks, have posted a bug report. FB7589564Got caught up and didnt get back here again, and, quite honestly, I'm embarassed to let anyone see the code.Compile bug still occurs in Xcode 11.4 beta 2.One of the 2 compilation errors disappears if I make a change to a file that references it.

Where you able to create a test project that showed it, or did you submit a bug report with whatever project your working on?

Certainly sounds similar. Thank you for posting that bug report and making a small testcase. Have you also filed it as a bug against Xcode using Feedback Assistant? If not probably worth doing.I'd have gone for higher than medium priority, just because I can't do anything with that code while getting that error 🙂

Claude31 the compiler in Swift 5.2 is reacting to the code base differently that it did in 5.1I could post code snippets that show that the binding is being initialised and where its declared but it isn't going to allow you to help. This appears to be a compiler bug, and as other replies to this thread show, I am not the only one affected. I copied some of the exact code out into a seperate project and it compiled fine (a SwiftUI view, with the Binding, and where the @State is set). It is something that is coming up as a cummulation of the compile process.However Vlas above has managed to create a very specific set of code that does demonstrate the issue.

Changing the List to a ScrollView & ForEach does work.

Yes, that definitely works as a workaround.Thank you. Going to mark it as a 'correct' answer

Can confirm that it works perfectly. Any view inside the WindowGroup works, I preferred it a bit deeper in my hierarchy attached to the button the triggers the webview for login, so that I'm not importing the library I'm using into the App file.

I am having the same issue, onChange is not capturing the previous value. Note, I am able to attach .onChange to the body view and have it compile.

This has been driving me a little insane. Soon as my app starts it dies with this error. Hadn't managed to figure out the cause of it, so thank you. I'm getting the error on 14.0GM, and 14.2b1, with the App built with either Xcode 12b6 or Xcode 12.2b1 (on a DTK). Had thought it was DTK related, so this is kinda good news. I was using a couple of multicolour SF symbol's, "text.badge.plus" and another I can't recall. Edit: So it is just the call to .renderingMode(.original) that is causing the crash. Commenting those out the app works fine.

Navigation bars aren’t working for me at all in 14.5 beta 1 device or simulator. On iPad they only work once. On phone there is no navigation bar regardless of hidden or not.

Crazy, but this still seems to be an issue. Even on Xcode 13.3.1. My simulator is running with 90-100% even though its doing NOTHING.

Interesting.

Adding an iPad target, and running the code is an iPad simulator worked perfectly.
