Where's Swift Compiler?
I know that swift compiler was never exist in sololearn, but I found this code https://code.sololearn.com/cw3Q4DKWs3tv/?ref=app Written in swift with sololearn. How could this happen? Where's that swift compiler? Because i don't know that swift compiler is exist in sololearn😱 Oh, extra question: If this is a bug, then why sololearn does not want to add online swift compiler???
