How quickly do iOS manuals get outdated?

Question

iOS

In particular, is iOS Programming: The Big Nerd Ranch Guide 4th Edition still up to date? And what about iOS with backward compatibility? Under iOS, in general, you can write so that the code then obviously works on subsequent versions of iOS and on devices with different (and not yet existing) screen resolutions (I'm not talking about games where there may be bitmaps tailored for a specific screen, with them all clear)? As a person familiar with Qt, where the interfaces are “rubber” from birth, I am confused by the conversations of iOS developers about the need to adapt the application for each new device. Or is it not so bad?

Answer 1

Every year WWDC, where new chips in development for iOS are presented. It is quite possible that you do not need all of them in your daily work, but you do not need to rely on what you once wrote and it will not need to be changed in the future and adapted to new requirements. The UI is quite stretching for itself, but there are flaws that, with not very competent development, you can make yourself. Well, the question is - the 64bit architecture is coming out and, after all, the application needs to be adapted. In short .. All sorts of books are useful only for the first start. Then official documentation, Google, wwdc, stackoverflow, articles on Habré.. In the literature, all this will be described with great delay, especially in Russian. So 2-3 years, during which a lot can change in the SDK and the platform. Integration with iWatch, for example .. And I doubt it far
