Property `_statusBarTintColorLockingControllers` at `UIApplication` keeping ViewController in memory

Question

Using Xcode 8 new memory debugger I found out there was a ViewController in memory that shouldn't be there and the strong reference that was pointing to it was coming from this mysterious _statusBarTintColorLockingControllers array in UIApplication. Does anybody know where it comes from? And more importantly, how to take my VC out of it?

Answer 1

_statusBarTintColorLockingControllers seems not to be the real issue here. I had the same memory graph until I resolved a retain cycle where I forgot weak on a delegate property.

Answer 2

I was stuck with same problem when forgot to set some property to nil before dismiss my controller
