Today when I tried to create a new project I quickly noticed that I got an error:"an internal error occurred. source editor functionality is limited. attempting to restore"Which is weird, a project that was created literally 5 seconds ago shouldn't have any errors, right?So I closed it and opened an older project, no errors there.Next I deleted the new project and recreated it. Still the same error.I cleaned derived data, restarted Xcode, restarted my mac, even went as far as completely uninstalling Xcode and then reinstalling it, but I still get the same error.Not only does that error stop me from using auto-completion and other nice editor features, but also from creating outlets for my viewsHopefully someone here has an idea how to fix this.

As the title says, when I try to add a Toolbar with a Button to my NavigationSplitView I get a warning about satisfying constraints. Here is a minimal reproducible example: import SwiftUI @main struct ViewTestingApp: App { var body: some Scene { WindowGroup { NavigationSplitView { Text("Sidebar") .toolbar { ToolbarItem(placement: .topBarTrailing) { Button { debugPrint("Hello World!") } label: { Label("", systemImage: "flame") } } } } content: { Text("Content") } detail: { Text("Detail") } } } } This is the specific warning I get: Unable to simultaneously satisfy constraints. Probably at least one of the constraints in the following list is one you don't want. Try this: (1) look at each constraint and try to figure out which you don't expect; (2) find the code that added the unwanted constraint or constraints and fix it. (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints) ( "<NSAutoresizingMaskLayoutConstraint:0x600002164960 h=--& v=--& _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x100f80fa0.width == 0 (active)>", "<NSLayoutConstraint:0x600002160370 _TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x100f80fa0.leading == _UIButtonBarButton:0x100f7d360.leading (active)>", "<NSLayoutConstraint:0x6000021603c0 H:[_UIButtonBarButton:0x100f7d360]-(0)-| (active, names: '|':_TtCC5UIKit19NavigationButtonBar15ItemWrapperView:0x100f80fa0 )>", "<NSLayoutConstraint:0x600002160050 'IB_Leading_Leading' H:|-(2)-[_UIModernBarButton:0x100f7e6c0] (active, names: '|':_UIButtonBarButton:0x100f7d360 )>", "<NSLayoutConstraint:0x6000021600a0 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x100f7e6c0]-(2)-| (active, names: '|':_UIButtonBarButton:0x100f7d360 )>" ) Will attempt to recover by breaking constraint <NSLayoutConstraint:0x6000021600a0 'IB_Trailing_Trailing' H:[_UIModernBarButton:0x100f7e6c0]-(2)-| (active, names: '|':_UIButtonBarButton:0x100f7d360 )> Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger. The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKitCore/UIView.h> may also be helpful. The project settings are all at their defaults, but in case anyone wants to try it with the whole project: https://github.com/OddMagnet/ViewTesting
