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.</div><div id="yui_3_16_0_1_1474204230469_5837"><br id="yui_3_16_0_1_1474204230469_5838"></div><div dir="ltr" id="yui_3_16_0_1_1474204230469_5839">Here's the code:</div><div dir="ltr" id="yui_3_16_0_1_1474204230469_5839"><br></div><div style="margin-top: 0px;
