How to cast Array<String> to NSArray full of NSString

Question

In working with CloudKit, all types need to be Objective-C foundation classes. Since most types used in CloudKit are bridged from Swift to Obj-C there isn't any issue (i.e.

record[key] = 1 as NSNumber

), but I'm having trouble converting an

Array<String>

to the appropriate CloudKit type (a string list in the CK dashboard). I figured

record[key] = ([myString] as [NSString]) as NSArray

would work, but no such luck. How can I convert this?

Just bridging will work, together with NSArray's array constructor:

let a = ["a", "bc", "def"]
let nsa = NSArray(array: a)
nsa[0] is NSString // *** true ***
