Writing a String to an NSOutputStream in Swift

Question

I\'m trying to write a String to an NSOutputStream in Swift. Writing Strings that way with Objective C usually works by passing it as NSData

Hope this example helps out. It writes a string to document directory. Note that outputStream is tested using Swift 1.1 with failable initializer.

var myString = "Hello world!"
var docPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var path = docPath.stringByAppendingPathComponent("doc")
var outputStream = NSOutputStream(toFileAtPath: path, append: false)
var data: NSData = myString.dataUsingEncoding(NSUTF8StringEncoding)!
var buffer = [UInt8](count:data.length, repeatedValue:0)
data.getBytes(&buffer)
outputStream?.open()
outputStream?.write(&buffer, maxLength: data.length)
outputStream?.close()
