www.hackingwithswift.com is a great site to get information on Swift. The pages cover a wide variety of topics in a concise manner that works well when you need just a bit of help. The pages have many examples of code, along with multiple books that can teach all levels of Swift programmers – from a beginning programmer, to an expert. There is always something new to learn and this page can supply it.

Colors Of The Apple World.
I am posting this because it’s a page that I’ve been spending a bit of time with today. I often have to look up what Apple calls many of its system colors – beyond the simple primary colors. The documentation that Apple provides does a really good job of showing you the various colors, their uses and how they are affected by light or dark mode. Needless to say, this is a necessary page for any Apple interface designers.

SwiftUI – The Best Interface Builder That Wants Me Dead.
I have been spending a lot of time trying to build an interface for a new version of one of my apps. I had a layout that was working visually, but unfortunately SwiftUI wasn’t up to making it work as it should. I have remade it multiple times over the last week in order to get buttons and pickers to work as they should.
Finally, tonight things started to work. I wish I could explain why they didn’t work in the first place, but oh well. It isn’t perfect and I still have a lot of things to add, but it is working.
I really like the idea of SwiftUI. It offers a nice escape from the usual interface builder and the never ending fight with constraints. But, it still has a lot of bugs that need to be squashed before it will really take off.
For me, my two fights were problems deleting pickers in a list, or making the keyboard pop up and work properly with those pickers. Most apps aren’t going to use a collection of pickers that need to be added and deleted, so my problems won’t help many of you. I ended up having to do some odd workarounds to make the delete happen. The keyboard issue kind of fixed itself in the process of attempting a ton of different ideas. I have since cleared out close to 200 lines of code that were added during my attempts to make it work. The most surprising part – it STILL WORKS. Yeah, I’m as shocked as you are.
If you want to develop your app with SwiftUI, go for it – but only if you have some time to work around its internal issues.
Here is a link to a page that answers many basic questions about SwiftUI and also a great rundown of the various features and how to use them: Fucking SwiftUI.
