Итак, как вы это делаете?

Вот функция из проекта RUI с неполной таблицей.
char * keyStringForKeyCode(int keyCode)
{
// Proper key detection seems to want a switch statement, unfortunately
switch (keyCode) {
case 0: return("a");
case 1: return("s");
case 2: return("d");
case 3: return("f");
case 4: return("h");
case 5: return("g");
case 6: return("z");
case 7: return("x");
case 8: return("c");
case 9: return("v");
// what is 10?
case 11: return("b");
case 12: return("q");
case 13: return("w");
case 14: return("e");
case 15: return("r");
case 16: return("y");

Почти тот же код, что и в ответе Гурно, но для языка Swift
(!!!) Эти сопоставления верны только для американской раскладки клавиатуры QWERTY.
