GM release of Xcode 6 compile

Question

I just downloaded the GM release of Xcode 6 and it won\'t compile with this error:

Command /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault         


        

Answer 1

In my case Xcode gave the error because of the following line :

if UI_USER_INTERFACE_IDIOM() ==  UIUserInterfaceIdiom.Phone {


}else {

}

And to fix the error I've defined this :

enum UIUserInterfaceIdiom : Int {
    case Unspecified
    case Phone // iPhone and iPod touch style UI
    case Pad // iPad style UI
}

And then i used it like :

 if UIDevice.currentDevice().userInterfaceIdiom == .Phone {

}

Good luck !

I was also getting this error. I ran the the command in Terminal as suggested by @Maxwell and found out the error was in my GameViewController.swift file. A little digging around and found that it didn't like some auto-generated code or the code conflicted with a setting in Xcode somewhere

override func supportedInterfaceOrientations() -> UIInterfaceOrientationMask {

    if UIDevice.currentDevice().userInterfaceIdiom == .Phone {
        return .AllButUpsideDown
    } else {
        return .All
    }
}

As soon as I removed this block the error went away.

In my case i changed 3 places:

Target > Build Settings > Swift Compiler >

• Optimization Level.
  • Debug: None [-Onone]
  • Distribution: Fastest [-O]
  • Release: Fastest [-O]

When i changed just Debug, i have errors like "Source Kit crashed...." This combination of parameters, works very good for me!

I think it occured for many reasons, what I have encountered is this situation,hope it could help you.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0) ){ [weak self] in

        // ...
        dispatch_async(dispatch_get_main_queue()) { [weak self] in

            // ...
            return

        }
    }

In the upper code,just delete "[weak self]" called capture list will remove the compiler error. It works for me.

dispatch_async(dispatch_get_global_queue( DISPATCH_QUEUE_PRIORITY_DEFAULT, 0) ){ [weak self] in

        // ...
        dispatch_async(dispatch_get_main_queue()) {

            // ...
            return

        }
    }

xCode version is 6.1.1

Answer 5

Encounter this error when compiling this Swift 2.0 syntax in Xcode 6.4:

print(string, appendNewline: true);

Back to Xcode 7 and the error is gone.

Answer 6

In my case this error was caused by the incorrect (UTF8) .swift file encoding; Solved by copy-pasting the file's contents into a new file.
