Transforming operators in RxSwift serve the purpose of preparing data coming from observables before it reaches the subscribers. Let’s cover this type of operators and look at 3 operators you will be using all the time.
After using RxSwift for several months now, I can safely say that filtering is a key feature that has saved me plenty of lines of code. To know which filtering operators to use when, requires a basic overview, so let’s look at 7 of my favorite filtering operators this library has to offer.
As an iOS developer, the iOS app lifecycle is an area you can’t skip out on. Knowing how to hook into the individual state changes is just as important. Therefore, let’s get familiar with implementing lifecycle hooks in your apps.
Knowing about the states that iOS apps go through as they run is key to building solid apps. You’ll find that it’s an often asked interview question, so now is a good time to listen up. We’ll look at the essentials of the iOS app lifecycle, so you can prepare apps for any state changes.
So there you are. New to Swift and trying to wrap your head around the so-called optionals. Speaking of “wrapping”, let’s take a closer look at this wrapper-type and unwrap this feature of the programming language.
Congratulations! You have decided to become an iOS developer and perhaps make a career out of it. So now it’s time to get started learning the application framework. So here are my recommendations of online video courses to go through to get your feet off the ground.
