When working in Xcode and deliberatly making errors in my code (using Swift 2) (e.g. using undefined variables, wrong type casts, ...), Xcode doesn't seem to show compiler errors in my code.I included a screenshot of some code I wrote in a playground, executed on my computer, and the same code a friend of mine executed on his:mine (the output on the left is output before I made the error, it just didn't update after my alterations)friend'sI hope someone can help me since this is becoming rather annoying,Thanks!
