Randomly create rectangles

I want to add a background to my app that consists of falling squares. What is the best way to go about this? That squares must continuously spawn at the top of the screen, then slowly fall and disappear at the bottom. I am currently trying to to use the CGRect Command, but nothing is appearing in my simulator. Thanks in advance!

'''swift var rectangle = CGRect(x:0, y:0, width: 100, height: 100) '''

It looks like you are skipping the steps of creating CGContext adding the Rect to the context and filling the CGRect...

I'd read up on those items to see where they fit in.

If you'd like some sample code to get you up and running, here is a good example - it has more than you need, but includes a solution to your problem...

The community is always happy to help, but it's tough without seeing your code.

If you post it in here, I'm sure you'll get some useful feedback....

Thanks for updating your initial question with the code, that makes all the difference!
