With WatchOS7/Xcode12 using the SwiftUI App Lifecycle you won't have a storyboard.

There is now an AccentColor within the App assets which is how you can change it.

At this point for change color of navigationBarTitle their is no direct api in SwiftUI.

But you can change it like this,
1) Go to Interface.storyboard file inside your AppName WatchKit App.
2) Select Hosting Controller Scene, Go to File Inspector and change Global Tint to your Custom Color.
