100daysofswiftui 100 Days of SwiftUI — Day 14 I skipped yesterday's part of 100 Days of SwiftUI, as I had a very stressful day at work and afterwards, it was pretty late and there wasn't much energy left. So, today was

100daysofswiftui 100 Days of SwiftUI — Day 12 I'm nearly done with the first part of the SwiftUI-course: Tomorrow starts the review of the Swift-part and today was basically the last day about Swift-basics. And the only important thing missing were
100daysofswiftui 100 Days of SwiftUI — Day 11 While suffering a minor hangover I just finished Day 11 of a hundred. It was about protocols, extensions and protocol extensions. As I'm not very concentrated today, this might have affected the test
100daysofswiftui 100 Days of SwiftUI — Day 10 Day 10 was about classes. In my opinion, Paul did a terrific job in explaining the differences between classes and structs. At least I think I actually understood that these two types handle
100daysofswiftui 100 Days of SwiftUI — Day 9 Ninth day of a hundred, ninth blogpost. I guess, you know the drill. Todays topic was structs again. Paul explained memberwise initialzers, access control — public and private — and lazy and static properties. I

100daysofswiftui 100 Days of SwiftUI — Day 7 Seventh day means seventh blogpost. Today was the second day about closures. I still find them hard, but they somehow make more sense to me now. I also appreciate that Paul split this
100daysofswiftui 100 Days of SwiftUI — Day 6 Today's my sixth day of 100 Days of SwiftUI and today was about closures. I've struggled with them so far as I find them pretty hard. And it seems, I'm not the only
100daysofswiftui 100 Days of SwiftUI — Day 5 Today's lessons of Paul Hudson's 100 Days of SwiftUI were about functions. What was actually pretty new to me was that Swift supports variadic functions — I'm not sure what they should be good
100daysofswiftui 100 Days of SwiftUI — Day 4 Day 4 was about loops. I learned how to exit outer loops when using nested loops — you can use so called labels and break label and that's it: outerLoop: for i in 0.
100daysofswiftui 100 Days of SwiftUI — Day 3 I just finished the third day. For the first time, I watched the short videos instead of reading the text like on the first two days. Today was about operators and conditions, no
100daysofswiftui 100 Days of SwiftUI — Day 2 The second day of a hundred took me like 20 minutes. Today's topics were more complex data types: arrays, dictionaries, tuples and enums and when to use each of them. I learned, that
