  • SR-138 Foundation objects are not bridged on Linux as they are on OS X.

Issue Description:

On macOS, I seem to be able to consistently cast NSData objects to Data:

let n: NSData
let d = n as! Data

On Linux, this consistently fails at runtime. I've tried this with Swift 3.1.1 and a Swift 4 snapshot with the same results.

We're trying very hard to avoid introducing this kind of bridging on Linux, since it makes the runtime more complicated and affects performance. But it is still a giant pitfall for writing cross-platform code right now.
