In Xcode 14 RC, I'm seeing this in the Console:

[Assert] UINavigationBar decoded as unlocked for UINavigationController, or navigationBar delegate set up incorrectly. Inconsistent configuration may cause problems. navigationController=<MasterNavigationController: 0x135016200>, navigationBar=<UINavigationBar: 0x134f0aec0; frame = (0 20; 0 50); opaque = NO; autoresize = W; layer = <CALayer: 0x600000380be0>> delegate=0x135016200

The above message displays exactly four times immediately at app launch (top of the console) then does not repeat.

MasterNavigationController is the internal class for the app's navigation controller. It is in a Storyboard, with very minimal ObjC code. I am not setting any specific size for the nav bar.

I don't remember seeing this in earlier builds of Xcode, but I can't swear to it that this is new. No assertion actually fires.

Same! I only added NavigationBar, almost no code in the project, but this error displays.

Inconsistent configuration may cause problems. navigationController=<UINavigationController: 0x109822e00>, navigationBar=<UINavigationBar: 0x108b2aef0; frame = (0 44; 0 50); opaque = NO; autoresize = W; layer = <CALayer: 0x280d5f2e0>> delegate=0x109822e00

Same issue we also facing... in OS 16 after splash screen showing black screen only.

After setting rootViewController call makeKeyAndVisible. This work for me.

self.window?.rootViewController = navigationVC self.window?.makeKeyAndVisible()

Calling makeKeyAndVisible does nothing in my apps to silence this. There must be another reason for it.

Could it be apps where the interface files were created a long time ago?

Interface builder files were created a LONG time ago. Never had an issue with iOS 12, 13, 14, or 15.

This happens in a brand new project. I created a basic iOS app. In the storyboard, added a navigation bar controller, set that as the initial view controller, and set its root to the original view controller. Log is spammed once with that warning. Seems Apple needs to clean something up; especially if newly created projects will exhibit the same issue.

I just reported this.....iOS has so many alarmist system logs now devs have no way of controlling.

Interesting. Apple's system here is auto-generating a hyperlink for the Feedback identifier. Yet it is excluding the last digit in the link. Guess I'll file another bug. Putting the identifier in quotes was an experiement to see if the link would get fixed.

This is only an iOS 16 issue because when I run the app on my iPhone with iOS 15.6 these warnings don't show up.

Same...I faced this error after ios 16 upgrade, and only displays on iOS16 device. The error only displays if I create UINavigationController in storyboard. In my source, I create a UITabBarController with 4 tabs(UINavigationController) in storyboard, so the message displays 4 times. Then I changed to create UINavigationController in code, the error dose not showing.
