OK, but has bugs and a lot of missing conversations

The conversion from ObjC to Swift works on approx. 80% of the code. That is a start, but due to lack of documentation I do not know where to start to add more/better rules.
The worst thing though is that as of version 1.2 I cannot use the App any more because I cannot specify source and target folders. The file dialog does not appear.
