swift - '[AnyObject]?' does not have a member named 'Generator' -

i looping through contacted physics bodies game, getting strange error anyobject. var bodies = island1.island.physicsbody?.allcontactedbodies() body : anyobject? in bodies { }

bodies here optional. you've gotta unwrap before can iterate it.

if let bodies = island1.island.physicsbody?.allcontactedbodies() {     body in bodies {         // etc     } } else {     println("there no bodies") }
