Swift developers, how is the evolution of the programming language now? does it still have backwards compatibility issues or things are more stable now (and will be with this new proposals)?
The Swift 3->4 migration was not bad, actually–just a couple of small changes to source here and there. With ABI stability I think we'll see the adoption of Swift for libraries and frameworks increase significantly.
I started out building prototypes with Swift 2. The migration to 3 caused a few headaches for me, and some migraines for others it seems. 3 -> 4 was relatively simple. Though, my experience was far less involved than those depending on Carthage/CocoaPods packages.
