Array and Dictionary type declarations in Swift

According to my understanding of the documentation, this should be correct:

var cookies: [NSHTTPCookie] = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies as [NSHTTPCookie]

where I'm creating an array of NSHTTPCookie objects. The interpreter does not like this syntax, however, giving me "Expected type after 'as'" and putting a little pointer at the opening bracket of the [NSHTTPCookie] at the end.

However, this works:

var cookies:NSHTTPCookie[] = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies as NSHTTPCookie[]

From the documentation, it seems like the first version is more correct, however.

Here's another example, this time with someone else's code. No one else using this code has reported the same behavior I get. (This is just a snippet; if the context is relevant let me know and I'll post more)

func asDict(x: AnyObject) -> [String:AnyObject]? {
    return x as? [String:AnyObject]
}

In this case the playground interpreter objects in both places [String:AnyObject] is used. It just doesn't seem to be recognizing it as a type.

I double-checked to make sure I have the most recent beta of Xcode 6, but it seems much more likely to me that the problem is in my understanding rather than in the tool, since this would be a mighty big bug for only me to experience.

You must be using an old beta, this works in Beta 5 playground:

import Foundation

println("hello")

var cookies:[NSHTTPCookie] = NSHTTPCookieStorage.sharedHTTPCookieStorage().cookies as [NSHTTPCookie]

println("goodbye")
