Day 35: Edutainment App. Review my work so far?

Forums > 100 Days of SwiftUI

Hello!

I'm very new to iOS development and am seeking some guidance on how I am doing thus far. I have compelted the funcionality portion of the Edutainment app, and am asking what I could potentially do differently or if what I have thus far is solid. Sorry if this is not something thats welcome here, but I want to make sure I am on the right path :)

ALSO: I am aware that I have no styling and its a very ugly version of the app, but I want to make sure the functionality is solid before I move on to making it pretty.

Thanks all!
