Problem

Extension to the String type that allows initializing a String from a tuple of 16 Int8 values, where the tuple represents a C-style null-terminated string.
typealias Tuple16 = (Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8, Int8)
extension String {
    init(tuple16: Tuple16) { ...
let tuple: Tuple16 = (72, 101, 108, 108, 111, 44, 32, 87, 111, 114, 108, 100, 33, 0, 0, 0)
let string = String(tuple16: tuple)
XCTAssertEqual(string, "Hello, World!")

let emptyTuple: Tuple16 = (0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)
let emptyString = String(tuple16: emptyTuple)
