Hi all,
Another question. I used to use this snippet to read keyboard input from
XCode's Playground. And it used to work very well. Today, I just updated my
XCode to v.8 and Swift v.3. After a little bit modification here and there due
to Swift 3 incompatibility, I got this code compiled without error. But it
doesn't work. No keyboard input is taken. It just stucks.
Here's the code:
import Foundation
func input() -> String { let keyboard = FileHandle.standardInput let
inputData = keyboard.availableData let encoding = String.Encoding(rawValue:
String.Encoding.utf8.rawValue) let strData = String(data: inputData,
encoding: encoding) return strData! as String}
func write(_ txt: String) { print(txt, terminator: "")}
func read() -> String { let c = CharacterSet.whitespacesAndNewlines return
input().trimmingCharacters(in: c)}
/* main program */
write("Enter your name: ")let s = read() So, does anyone know how to make it
works (again)? Thank you.
Regards,
–Mr Bee
