Ask HN: Swift or Objective-C for new iOS app in 2017?

I am still coding with Objective-C for production apps. Random SourceKit crash on Xcode causing auto-complete to go haywire impede productivity especially you are in the flow.

And to adapt to new syntax whenever a new Swift version come out... is painful

Swift for your own code. Choose ObjC for any 3rd-party frameworks and libraries otherwise you risk being stuck waiting for them to be fixed when swift is upgraded.
