> Any way to pass the bytes directly to String without an intermediate copy? You can do this with `UnsafeBufferPointer`. For example: extension String { init?(bytes: UnsafePointer<UInt8>, count: Int) { let bp = UnsafeBufferPointer(start: bytes, count: count) self.init(bytes: bp, encoding: .utf8) } } I don’t know if this is faster. There are lots of different ways to achieve your two goals and I wouldn’t even start optimising this without a realistic model of what your strings look like in practice, and a performance test based on that model.
