Recently, I've been busy doing a small project, I've done the backend and website part a while ago, and today I started to write the iOS app part which I've been delaying for a long time. In fact, I'm new to iOS development, and I haven't done many mobile projects in the past, but I've done some for Android, so I've always felt that I've encountered a lot of difficulties.
Last year, I used to learn to write the interface with the book, at that time, I used the book for iOS 12, I made a small app and then I was busy with something else, one year later, I bought the e-book at that time and it has been updated to iOS 13. I looked at the content because the book has not been updated significantly, or I taught it slowly from the Storyboard, and I didn't think there was a lot of difference, so I spent the afternoon actually applying the things that I learned to the new app, and I managed to finish the work of carving the basic interface. I spent the afternoon actually applying what I had learned before to the new app, and managed to finish the work of carving the basic interface.
After dinner, I accidentally flipped to the iOS course opened by stanford in 2020 spring, decided to watch it while exercising, and realized that Swift UI is really much better (at least for me, a lazy coder who doesn't like to pull and pull to carve interfaces). So at night with the mood of practice to see the interface carved out in the afternoon with the Swift UI approach to do it again, just by casually exercising while watching a small part of the knowledge absorbed, plus worship Google god, surprisingly, within an hour to find a complete set of components, and even by the way to the original afternoon felt tired of carving can not write the logic of the part is also complete the whole of the Swift UI! The whole Swift UI friendliness is amazing.
可以看出蘋果在發展Swift上確實有長足進步，一個小時就有回不去的感覺。不知道是不是因為我iOS開發經驗太少，所以覺得新玩意學起來容易。不過這樣一來，原本還想像要成為認真的iOS app開發者回去用objective C慢慢刻的情景大概就不太會實現了…？
