allenwong/30DaysofSwift ? reverse-engineered prompt

Build me a Swift learning app that recreates this 30 Days of Swift collection as a set of small demo screens I can tap through.

I want each screen to feel like a tiny polished iPhone project, with things like a stopwatch, custom fonts, local video playback, animated menus, pull to refresh, location lookup, login and splash animations, emoji slot machine, swipeable cells, Core Data, tab bars, spotlight search, image picker, and a fun final face or image related demo. Keep it simple and clean, but make the transitions and animations feel smooth and modern. If you need to look up current Apple docs online, do that.

Please set it up so the app opens to a home screen with all the demos listed clearly, and each one launches its own example view without crashing. I care more about a nice learning experience and working interactions than perfect design.
