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

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
