What does it mean ? I haven't added UINavigationBar in my project. UINavigationController is embedded through editor -> Embed In -> Navigation Controller.
[Assert] UINavigationBar decoded as unlocked for UINavigationController, or navigationBar delegate set up incorrectly. Inconsistent configuration may cause problems. navigationController=<UINavigationController: 0x13b80c600>, navigationBar=<UINavigationBar: 0x13b5079f0; frame = (0 0; 0 50); opaque = NO; autoresize = W; layer = <CALayer: 0x600000f56620>> delegate=0x13b80c600
