UITabBar BarTintColor not working on iOS15 Developer Beta 5

I updated my iPhone to the latest iOS15 Developer Beta 5 and noticed that the UITabBar's barTintColor is no longer working.

I am running Xcode Version 13.0 beta 4 (13A5201i). When I run on the emulator it has the correct barTintColor.

But when I run it on my iPhone (IOS15 Developer Beta 5) this is the result on my UITabBar.

But both screenshots has the same code.

tabBar.barTintColor = UIColor(red: 0.141, green: 0.165, blue: 0.216, alpha: 1)

If anyone can make sense out of this would be great.
