Summary:
I'm getting an error from the compiler i can only describe by an example. I'm receiving an array of the type [AnyObject] from a Foundation-method but i know that it only contains strings, and i want to filter these strings by two criteria. The following example outlines that code:

let objects : [AnyObject] = ["1", "2", "3"]
let allFiles = (objects as [String]).filter { $0.pathExtension == "strings" && $0.rangeOfString("findme") == false }

Now I'm getting the error "'AnyObject' is not identical to 'String'", pointing at the [String]-cast. But when i remove the second criteria within the filter-closure, i don't get that error and it works as expected:

let objects : [AnyObject] = ["1", "2", "3"]
let allFiles = (objects as [String]).filter { $0.pathExtension == "strings" }

So, the content of the closure impacts the compilation of the cast? I don't know if it is more related to the closure or the cast, in any case, this is an odd behavior.
