I’ve been devastated last two days looking and reading about all kind of errors. And I found similar issues but when I try to fix mine, it never works.
I’m almost ready to submit my project and it was working amazing. However, suddenly when I try to run the code, it builds fine but when it runs, it stays on the launch image and then it crashes. I’ve tried it both on the simulator and the device, same thing.
Though, when it runs my Xcode takes me to this line which I absolutely understand, not.
#import <UIKit/UIKit.h>
#import "AppDelegate.h"
int main(int argc, char *argv[])
{
@autoreleasepool {
return UIApplicationMain(argc, argv, nil, NSStringFromClass([AppDelegate class]));
}
}
It simply points there with no error than: Thread 1: signal SIGBRT
and the Output shows this:

If you please understand a word from this guide me. I’m really lost.
I feel it happened when I linked my UISwitch but I’ve tried disliking it, deleting it, commenting all the codes and still same thing!
I’m a beginner but a fast learner so please elaborate and ask me if you need more details.
Check in IB that you have connected all of your outlets. I often get this when I accidentally wind up with two connections to the same UI element, usually because IB doesn’t undo very well.
