well for backend development, yes - I technically never stopped as I had existing projects to maintain. But after trying out Swift a couple times, I've dropped it entirely for backend. For new backend work it's C#/.NET all the way.

I wanted to try using a native language other than C++ and Swift ostensibly seemed easier to pick up. I continue to use Swift for iOS app development though where it is much easier to use; but that has its own share of compromises and trade-offs - but not centred around Swift, around SwiftUI vs UIKit.
