[swift-users] Swift 3 version of creating a string from a pointer, length and encoding?

Next question in my migration. How do I do what this did in Swift 2.2?

let theData = String.init(bytes: data.memory, length: length, encoding: 

The only initialisers that have a length are

init?(bytesNoCopy: UnsafeMutableRawPointer, length: Int, encoding: 
String.Encoding, freeWhenDone: Bool)
init(utf16CodeUnitsNoCopy: UnsafePointer<unichar>, count: Int, 
freeWhenDone: Bool)

Neither is applicable.

Do I need to push it into a Data object first, like this?

let theData = String.init(data: Data.init(bytes: data, length: length), 
encoding: String.Encoding.utf8)

Or is there a better way that I've missed (highly possible)?
