Here is how to set UINavigation Bar Large Title Text Colour (Foreground Colour) in iOS 11, 12, 13 and above,

 
Declare Navigation Bar Title Text & Large Title Settings like this in your View Controller’s ViewDidLoad() Method:

 

self.navigationItem.title = "Home"
self.navigationController?.navigationBar.prefersLargeTitles = true
self.navigationController?.navigationItem.largeTitleDisplayMode = .automatic

 
Now write below line inside ViewDidLoad() to get Large Title Foreground colour as White Colour like this:

 

self.navigationController?.navigationBar.largeTitleTextAttributes = [NSAttributedString.Key.foregroundColor : UIColor.white]

 
Thanks & Regards
