On iOS 10.3 and prior, setting the `titleTextAttributes` foreground color on UINavigationBar (either via UIAppearance, or on an instance) also style the prompt text. On iOS 11, this is no longer the case.

I consider this a regression, as it isn't immediately obvious that the workaround is to style `UILabel.appearanceWhenContainedIn...`. The old API dropped functionality, without any Xcode warning or documentation notes that I'm aware of.

I've attached a sample project. Look in MainViewController.swift:Line 16.


Steps to Reproduce:
1. Add a dark bar tint color to a UINavigationBar, to make this more visible.
2. Set titleTextAttributes on the bar to color the foreground white.
3. Add prompt text to the visible view controller's navigationItem, so that it's visible. Also add title text.
4. Run the app on iOS 10.x Observe that the prompt is colored the same as the title text.
5. Run again on iOS 11.

Expected Results:
The prompt text color should match the title text color.

Actual Results:
The prompt text remains black.
