Swift 1.2 ?? operator

I just switched to Swift 1.2 and now it does no longer like

let v = optionalVal as SomeThing ?? default

Apple's release notes do not tell anything about it. Sure I can use if nil but the ?? was handy.

You just have to put it inside a parentheses and forced cast now needs an exclamation mark as! or as?:

let v = ( optionalVal as? SomeThing ) ?? default

UPDATE:

Apple has just released today Xcode6.3 Beta 2 and seems that it is not needed anymore:

Swift Compiler

This expression now parses correctly, without need for parentheses:

dict[someKey] as? Int ?? 5
