With Apple having more than a billion working iPhone devices, the demand for iOS devs has done nothing but risen over the years. The most challenging part of becoming an iOS developer is actually sitting down and realizing that the more you learn, the more stuff there is to be discovered. However, it’s important to know to balance learning and constantly learning because let’s not lose the vision – the ultimate goal of everybody is to get a full-time job as an iOS dev.
Eight times out of ten, you’ll be joining a company or a team that has a preexisting app. Of course, nobody can expect one to be a know-it-all, but some topics are significant and can be thought of as the fundamentals of iOS development.
Once you understand the basics, then everything else is just practice and gathering more and more experience because the experience on many occasions has shown off as more important than one’s theoretical knowledge. Let’s go over the basics.
Swift is pure code, a core programming language developed by Apple. Created for intuitive programming for macOS, iOS, tvOS, and others, Swift is robust and designed to give the developer a fun and interactive experience while offering more freedom than ever.
Aside from being easy to use, Swift is also open-sourced, meaning that one only needs the vision to create a unique and incredible code. All software ever written in Swift will run so smoothly that comparing it with a bolt of lightning would not be excessive.
Swift’s safeguards will prevent errors and improve the overall readability of the code, while its syntax will boost you to write a clean code. The language has gone under extensive iterations ever since its release in 2014 to make sure it could be used in both frontend and backend.
To develop an application, logically, you’ll use a lot of frameworks and libraries that will be compiled within the application’s code. So, what’s the catch here, and why is this important for app development?
Speed is quite important for an app, and whether or not all the third-party frameworks and libraries are static or dynamic has a lot to do with speed. Why should I keep third-party code as a part of my exe file when I’m not sure if that code will be used in the first place? That’s how static libraries operate.
They stick onto the initial code and become part of it, and no matter if the app is going to use the specific library this time, it will be loaded when the processor is loading the app itself.
While the static libraries are wasting valuable resources and time, the dynamic libraries are just linked to the app and loaded only when there is an actual need. Just for the record, Swift introduced this concept when it first launched back in 2014.
While Swift is the one that builds the application, SwiftUI is the one that makes an app look like an app. To be more precise, Swift may create the button, but SwiftUI is the one responsible for the design.
Swift and SwiftUI go together, hand in hand. Swift is the programming language, and SwiftUI the tool used to control the app’s user interface.
I think that SwiftUI is best described by Ish Shabazz’s own words:
“SwiftUI is basically rendering the view see is a function of state. As you’re typing, it’s re-rendering the views at that speed. And instead of just modifying a view, which is what you do with UIKit, you have this object, and you can change a property on it.”
Living in the early ’20s, the most important thing for the average consumer is to have interaction with the web. Which is totally understandable because what would you do with an interactive app that doesn’t actually offer internet access?
The chances of people interacting with such applications are minimal. That’s why it’s so important for a developer to understand networking concepts and actually put them in use so the user can send and receive data from a network.
In the beginning, the whole data transmission thing may sound scary and complex, but once you start swimming in those waters, you’ll see that the way it’s done is pretty straightforward.
Apple is the mastermind behind one of the most popular frameworks used to manage the model layer object – Core Data. It’s using SQLite, but the frame itself it’s not a database, although you can save, modify, and keep track of all data within an iOS application.
Furthermore, Core Data tracks the changes made in the data during one application session, and it’s used to retrieve the data once the current session is over and a new one is started. If it weren’t for Core Data, every time you’d close an app (terminate the application session), everything would be lost, and we don’t want that.
Why should iOS be your OS of choice?
One of the things iOS is best at is performance, without any doubts. Plus, if you consider the configurations it’s operating on, the decision to choose it, becomes a simple one. However, to ensure that the development of your iOS web project will go smoothly and without any obstacles in the way, you’d need a skillful iOS expert who can tackle the challenges.
Plain and simple, consider to hire iOS app developer for your iOs app because with thousands of apps on the market you’d need to stand out and impress your target users. Plus, with Android holding the biggest market share, a successful iOS app will attract more high-end users and bring more revenue than an Android app to its developers. The most attractive thing the iOS development center can offer to one as a developer is the wide number of dev resources.
iOS is the perfect platform if your goal is to build a user-friendly, sharp, and intuitive app that can be used even by a kid. Moreover, iOS devs have their job a lot easier than their colleague devs who work on the AndroidOS because they have to focus only on optimizing the application according to the latest version of the iOS-based devices.
