Until there is some stabilization of the language and its main libraries/ABI (coming in v3.0 or so), I don't think the language can really take off. The changes can possibly break it, is it really worth it to invest in something that next year will change breaking your code? From Swift v3 on we should start seeing things going!

They provide tools to port. So I think it depends more on how large your app is. For a small app running the tool and making a few misc fixes will probably be fairly easy. At least if it is like the 1.0 -> 2.0 change. For larger apps, well, I have a Swift app that isn't really very big, probably still small but significantly bigger than a tutorial, and it keeps freezing Xcode. (Edit something in Interface Builder, switch to the ViewController class with IBOutlets in it, then switch back and forth between ViewControllers making edits. Each time it takes longer and longer until I just force-quit Xcode to avoid twiddling my thumbs for 5 minutes.) So I don't think Swift is ready for any app that isn't pretty small anyway.
