Question: Everyone can code! commands are comments in Xcode 9.1
I updated the Xcode and the Intro to app development book and i downloaded the files for the Xcode 9/Swift 4. When i opened it, everything was comment. When i deleted and retyped the //, it worked but if i run it again, it went back to comments. I tried to reinstall Xcode or redownload the learning files but nothing.
What can i do?
MacBook Pro TouchBar and Touch ID, macOS High Sierra (10.13)
