NSData from Byte array in Swift

Question

I\'m trying to create an NSData var from an array of bytes.

In Obj-C I might have done this:

NSData *endMarker = [[NSData al

Answer 1

var foo : Byte[] = [0xff, 0xD9]

var data = NSData(bytes: foo, length: foo.count)

println("\(data)")

outputs: ff d9

var data = NSData(bytes: [0xFF, 0xD9] as Byte[], length: 2)

println("\(data)")

outputs: ff d9

Edit: Ah, you have to write 'as Byte[]', so then the results are the same

UPDATED for Swift 2.2

var foo:[UInt8] = [0xff, 0xD9]
var data = NSData(bytes: foo, length: foo.count)
print("\(data)")

outputs: ff d9

var data = NSData(bytes: [0xFF, 0xD9] as [UInt8], length: 2)
print("\(data)")

outputs: ff d9
