Recommendations for best iOS Gui Asset / Framework

I’ve been making my own iOS phone app interfaces from scratch in Unity, so far so good,
but I am reinventing the wheel every time.

Can anyone recommend a framework or kit on the asset store that has a modern iOS gui with swiping, scrolling etc.?

Sorry if it’s an obvious question, but I keep buying assets that only get me half way to my goal.

thanks!

To answer my own question - I bought this asset and it seems pretty good

still open to other recommendations if anyone has found a good framework.
