My colleague wrote part of his iOS app in Swift. He's now converting everything back to Objective-C due to bad performance and debugger issues.

Wow... I was worried about this and didn't make the switch for this reason. Yet, i was about to. Anyone else can confirm those issues ?

Switched, more productive due to more static-typed nature of language. Not seeing any problems other than slow Xcode autocompletion.

Same here, I've written toy projects and smaller apps in swift, but I'm running into lots of crashes when trying to debug. Not ready for production yet IMO.
