I love how easy it is, you can just drag files into your workspace folder or even drop them onto an existing swift file if that's what works better with their editor/IDE of choice! You're able get errors as well which helps when debugging but sometimes they don't give any indication about why something doesn;t compile so there isn'y much help beyond "you have this issue" unless its pretty obvious like missing curly braces etc.. It would be nice (and maybe more helpful)to see some kindof error message along side each line number saying where exactly whats wrong within my sourcefile though i guess thats not possible since those aren';r being written by me instead from compiler itself haha :P Its great having such tool available at hand especially considering all other tools are expensive compared tooo free ones outthere :) So far nothing really annoying here apart form few minor issues regarding compiling time - usually takes around 5min.
