I am following an Apple tutorial on creating an iOS Application using Swift [Developing iOS Apps (Swift)], and I have followed each step exactly as it is. This app has been running flawlessly in the Simulator, but suddenlly it started throwing a SIGABRT error (I made a short research to understand what a SIGABRT (Signal Abort) error is, and I've even found some other answers, but no one seems to fix my problem).
Console Output:
2017-10-25 02:00:23.553 myApplication[1358:48276] -[SWRevealViewController revealToggel:]: unrecognized selector sent to instance 0x7ff74c813400
