NSData to [Uint8] in Swift

Question

I couldn\'t find a solution to this problem in Swift (all of them are Objective-C, and they deal with pointers which I don\'t think exist in Swift in the same form). Is ther

Answer 1

It's funny but exist more simple solution. Works in Swift 3. Surely. I've used this today.

data: Data // as function parameter    
let byteArray = [UInt8](data)

That's all! :) NSData easily bridged to Data.

UPDATE: (due to Andrew Koster comment)

Swift 4.1, Xcode 9.3.1

Just has been rechecked - all works as expected.

if let nsData = NSData(base64Encoded: "VGVzdFN0cmluZw==", options: .ignoreUnknownCharacters) {
let bytes = [UInt8](nsData as Data)
print(bytes, String(bytes: bytes, encoding: .utf8))

Output: [84, 101, 115, 116, 83, 116, 114, 105, 110, 103] Optional("TestString")
