SwiftyObjC is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod 'SwiftyObjC'

guard/guard let

They are possible but not implemented because it has two significant flaws:

  • I can’t ensure else block has return/throw at compile time. Without this I find it too dangerous
  • I can’t ensure one wrote else keyword, so again dangerous.

However, I’m looking forward to implement these, so if you found a way how to trick compiler, feel file a note or PR.
