Swift programming design pattern

I'm building a small app and got two views. Now I'm wondering whether I should build it in two ViewControllers or just use an UIView as overlay.

Should I use a transparent viewcontroller over the currentcontext of view 01 or just a regular UIView?

View 01 looks like this:

View 02 looks like this:
