Spending too much time facing iOS 14 regressions. Last one found: Custom UISlider drawing might break due to internal layout changes: developer.apple.com/forums/t…. Time for a new workaround.

The Google Cast UI customization API is probably the worst I have ever seen: cocoadocs.org/docsets/google….
