Running code turns up with white screen

Hi,

Sorry to be bothering you all with this but im quite new to coding and i just cant get this work. I have been able to run the code with no errors but i am meeting issues when i Run the code and the "iphone" screen turn up all white.

I have been using Table View Controller Scene and put it as "Initial View Controller", but when i Run it i still just get a white screen. I believe i might have some issues when it comes to using capital letters some where and some not, but im not sure tbh if that is the root cause.

If you have time to come with some feedback that would be greatly appreciated and if not still greatly appreciated that you took a look.

(and sorry for the messy writing)

The whole code:

Part of the code:

`import UIKit
