100 Days of SwiftUI — Day 28
I missed yesterday, as life got in my way. But I didn't want to miss today, too, so I sat down before going to bed and just did Day 28: It was review time, again. I passed a small test and solved three challenges.
The last one was actually pretty tricky for me: I had to get rid of the button to start the bedtime-calcultion and show the calculated bedtime all the time instead.
