Пройдя поиск в сети, я обнаружил следующее (частично основываясь на этом ответе ):
import Foundation
extension FileHandle {
func enableRawMode() -> termios {
var raw = termios()
tcgetattr(self.fileDescriptor, &raw)
let original = raw
raw.c_lflag &= ~UInt(ECHO | ICANON)
tcsetattr(self.fileDescriptor, TCSADRAIN, &raw)
return original
}
func restoreRawMode(originalTerm: termios) {
var term = originalTerm
tcsetattr(self.fileDescriptor, TCSADRAIN, &term)
}
}
func getch() -> UInt8 {
let handle = FileHandle.standardInput
let term = handle.enableRawMode()
defer { handle.restoreRawMode(originalTerm: term) }
var byte: UInt8 = 0
read(handle.fileDescriptor, &byte, 1)
return byte
}
fputs("Press any key to continue... ", stdout)
fflush(stdout)
let x = getch()
print()
print("Got character: \(UnicodeScalar(x))")
