My first language was some awful proprietary BASIC dialect. It hasn't harmed me any, so far as I can tell. Learning one language, proprietary or not, gets you about 99% of the way to learning a second (potentially more open) language. And in any case, isn't the language due to be open-sourced pretty soon?

Mine was visual basic in school. Though we only had one year of that where we designed calculator gui before moving to C++. I don't think there are many bad habits to be learned from Swift though. It seems a decently designed language.
