How to change Status Bar Color on iOS 13 using Objective C?

**** good question.

It's quite easy actually:

UIView *statusBar = [[UIView alloc]initWithFrame:[UIApplication sharedApplication].keyWindow.windowScene.statusBarManager.statusBarFrame] ;
statusBar.backgroundColor = [UIColor whiteColor];
[[UIApplication sharedApplication].keyWindow addSubview:statusBar];

It is applicable the same code to Swift also?

you can use like this as well :

let statusBar = UIView()

statusBar.frame = UIApplication.shared.statusBarFrame

statusBar.backgroundColor = color

UIApplication.shared.keyWindow?.addSubview(statusBar)
