Commas at line end in Swift -


in swift xcode autocorrect keeps forcing me add comma @ end of line, don't know why or comma doing. commas @ end of line do? looked , found lots on comma use in phrase separate different values in function example, nothing why comma or used @ end of terminating line of code. code xcode wanted add comma (the comma @ end xcode): 

var firstrandomnumber = int(arc4random_uniform(uint32(playerarray.count)),

is glitch or there i'm missing?

thanks

basically it's bug in fix-it , compiler's interpretation of mistake. mistake really you've forgotten final right parenthesis:

var firstrandomnumber = int(arc4random_uniform(uint32(playerarray.count)))                                                                          ^

but compiler doesn't quite grasp that, , interprets missing comma:

these messages might improved in future version of swift.
