Type 'NSAttributedStringKey' (aka 'NSString') has no member 'foregroundColor'

问题

Below is line of code for the above mentioned issue. This issue is occurred in Swift 4.1.

let textAttributes = [NSAttributedStringKey.foregroundColor:UIColor.white]
navigationController?.navigationBar.titleTextAttributes = textAttributes

I've fixed this problem by replacing the Key for Attributed String.

Here is my updated Code is:

let textAttributes = [NSForegroundColorAttributeName : UIColor.white]
navigationController?.navigationBar.titleTextAttributes = textAttributes
