Output not showing and infinite/slow running

Evening, I'm relative newbie about Xcode.


I'm solving an exercise and in the Toolbar i can see that the running process is keeping running for ever.

Some times after several minuts it give me output and errors, some times it just keep running.


I was thinkg it was a problem of my code, but even starting a new playground the running process is ver very slow, like 1 minute to solve the example string variable.


I've tried to reboot xcode, reboot os, unistall and install again xcode but I still have the same problem.



Xcode Version 7.3.1 (7D1014)


Any tips?
