Xcode 15: App is crashing when setting custom Navigation bar for navigation controller

I have made a custom class for UINavigationBar which has all the custom features I need for an application. After initialising the class I am adding it to the navigation controller like this

if (!navBar) {
    navBar=[[NavigationBar alloc]initWithFrame:self.navigationController.navigationBar.frame];
    [self.navigationController setValue:navBar forKeyPath:@"navigationBar"];
 }

My app is crashing on the line

[self.navigationController setValue:navBar forKeyPath:@"navigationBar"];

Till Xcode 14 its working fine but on Xcode 15 it's crashing. Any help is highly appreciated.

below is the crash that I am getting

*** Assertion failure in -[UINavigationBar layoutSubviews], UINavigationBar.m:3856
Solution

  • I was able to solve the issue after putting the code in viewDidLayoutSubviews

    -(void)viewDidLayoutSubviews{
   [self.navigationController setValue:navBar forKeyPath:@"navigationBar"];
}

    After this code is working and not crashing anymore
