I just want to show a simple navigation title like the following.

import SwiftUI

struct ContentView: View {
	var body: some View {
		NavigationView {
			ZStack {
				Color.red.edgesIgnoringSafeArea(.all)
				Text("Hello")

			}
			.navigationTitle("GGG")
			.navigationBarTitleDisplayMode(.inline)
			.navigationBarHidden(false)
		}
	}
}

And I get a bunch of mumbo jumbo auto-layout warnings (Unable to simultaneously satisfy constraints...) in Console. If I comment out the navigationTitle line, I won't get them. I have never seen those messages in showing a navigation title when writing code with UIKit. What am I doing wrong? Muchos thankos

Testing your code with Xcode 12.5.1 on an iOS Simulator or an actual device of iOS 14.7.1, I could not see any messages in the debug console. I'm not sure if this is because of my environment or your environment.

Those may be ignorable (so called log noise) if they does not affect the app harmfully.

You can send a bug report to Apple with attaching your project and describing your environment precisely.
