UIButton showsTouchWhenHighlighted alters VoiceOver description?

Setting showsTouchWhenHighlighted, e.g. via the IB option "Shows Touch On Highlight," on a button without a title will alter the VoiceOver description. After reading the accessibility label, VoiceOver beeps and announces a description of the image. Is there a way to disable this behavior?

Keep Xcode 12 new tab interface tab opeen

The new tab interface in Xcode 12 italicizes tabs that don't stay open as seen as you open another file. I was wondering whether there is a keyboard shortcut to keep a tab open.

What is the “Swift Language Version” Xcode setting for? Because it still builds newer Swift code with an older version set

I'm building source code using an Xcode project that has its "Swift Language Version" set to "Swift 4." Even with this set, the project builds Swift 5.1 source code like, for example, implicit returns and Swift 5 source code using the new `isMultiple(of:)` method.The Swift 5 and 5.1 code still works even with "Swift Language Version" set to "Swift 4" or "Swift 4.2"It's only when running `#elseif swift(>=4.1)` statements that there appears to be a difference (code from https://stackoverflow.com/a/46080904/414415). Those results output their expected results.However, I'm left wondering, how does the my Swift 5 source code compile successfully when the build setting clearly states Swift 4? And if the setting does not change which version of Swift I can use, what does it actually do?
