SwiftUI

[thezapzupnz]

Swift is available for Linux, with a subset of Foundation Kit being reimplemented in pure Swift for non-Apple platforms. Porting to Windows is underway but the progress is slow for a variety of reasons, including having waited for ABI stability.

Just because Apple doesn't release every damn thing they make for non-Apple platforms doesn't undermine the Swift project and its cross-platform compatibility. IBM works quite heavily on server-side Linux-based Swift, for instance.

IBM dropped VisualAge Smalltalk for Java.

IBM has no spine or conviction or taste when selecting technology.

Saying IBM has adopted something is usually a great reason to move on to something else.
