This is the first "challenge day" of 100 Days of SwiftUI -- wherein we're asked to build a completely new app from scratch relying on the material covered so far.
You need to build an app that handles unit conversions: users will select an input unit and an output unit, then enter a value, and see the output of the conversion.
Which units you choose are down to you.
I ended up choosing two sets of conversions: Bitcoin-to-Satoshi, and temperature units. The former was straightforward, one-to-one comparison of currency values; the latter was slightly move involved -- with multiple segment pickers for switching among a handful of potential units.
Why would you want an app that specifically converted Bitcoin and temperature side-by-side. Not entirely sure — but a rewarding SwiftUI challenge nonetheless 😃.
