I'm trying to create an iOS app in Xcode using swift. the first thing i have done is add an image to the view controller and then i wrote some code in the ViewController.swift file. I also did add the picture file to my supporting files. I have the following code in my ViewController.swift file. When i run the simulator it will open the app and it won't show the picture it was just say the project name and then i think it crashes because the screen goes black. Can anyone please help me?
