Answer 1

Maybe this layout will fit your needs. Please take a look at this project: https://github.com/betzerra/MosaicLayout

I'm not sure 100% it will totally satisfy your requirements, but in the worst case it may help you in writing your custom UICollecionViewFlowLayout (which is the only way to achieve your goal)
