The app I’m working on currently (for multiplication tables practice) has a number type keypad and display a bit like a calculator - but for entering the answers. It’s been quite fun to think through all the little problems to make it work how you’d expect, so I was quite interested to watch an iOS Academy video where Afraz Siddiqui builds a partially finished SwiftUI version of the iOS Calculator app.
A YouTube channel worth subscribing to is Afraz Siddiqui’s iOS Academy . He does a great videos on iOS development. My favouriets might be the shorter focussed ones, like this one on the new SwiftUI chart views.
I seem to consume a lot of iOS Academy videos with great, short (< 10 minute) explanations of various Swift iOS programming topics - particularly little UI topics, like this one on the Grid View.
I really appreciate the generous content provision in the Swift and iOS development community. Perhaps this is the same for lots of technologies, but for someone who started programming pre-internet, it’s a stark difference to how I used to learn - so many magazines, and so many 2" thick books.
I had one of those synchronicity in learning moments this morning. I am reading The Swift Book - ie The Swift Programming Language, Swift 5.7 as part of my cs193p homework, and this morning, in a coffee shop was admiring what a clear, well written explanation was given for closures . It is super well written, stepping the reader through in logical (and digestible) steps.
If you’ve never carelessly passed around a pointer to a function and caused the Blue Screen of Death, or done much multi-threaded programming, the use-case for closures, and use of them is going to be challenging at first. Then Swift’s ability to cut the syntax down to very little will be challenging.
