Black screen in simulator

I created a file that had a button bringing you to another ViewController, and it worked fine. But all of a sudden when I would run the simulator, the screen on the iPhone would turn white and then black and I am not able to click the button or even see it. Below is the error that popped up in the debug error. "mmmmm" is the name of the file

Click on your Main View Controller. In the Attribute Inspector on the right, select Is Initial View Controller and the arrow will reappear. See the screenshot below:
