ESSENTIAL ELEMENTS YOU NEED TO KNOW TO BECOME AN IOS DEVELOPER
Apple Inc. invented the iOS operating system for mobile devices. The iOS is run on many mobile devices for Apple, such as iPhone, iPod, iPad, etc. An iOS developer is someone who knows everything about the iOS ecosystem, including an in-depth understanding of how it works on different Apple devices like the iPhone, iPad, Apple Watch, Apple TV, etc. In short, an iOS developer must understand how to build, develop, and customize apps in the iOS ecosystem.
The architecture of iOS is layered. It has an intermediate layer between the apps and the hardware that prevents them from communicating directly. In iOS, the lower levels provide basic functions, while the upper layers provide the user interface and advanced graphics.
iOS Architecture’s Layers
The different layers are illustrated in this diagram as follows
All the iOS technologies are developed based on the low-level foundation supplied by the Core OS layer. These technologies include the Security Services Framework, External Accessory Framework, Core Bluetooth Framework, Accelerate Framework, Local Authorization Framework, etc.
In the cure services layer, there are a variety of frameworks. Details about some of these are presented as follows
Core Motion Framework: The Core Motion framework is used to access all motion based data on the device.
Core Data Framework: The Core Data framework is used to manage the data model of the model view controller app.
Core Location Framework: This framework provides the location and heading information to the different apps.
Core Foundation Framework: This is where the iOS applications get their data management and service functionality.
CloudKit Framework: The CloudKit framework can be used to transfer data between the app and the iCloud.
Address Book Framework: The Address Book framework provides access to the user’s contacts database
HealthKit Framework: This new framework can handle the user’s health-related data.
AV Kit: This provides a variety of user-friendly video presentation interfaces.
Media Player Framework: This framework supports playlist playback and allows the user to access their iTunes library.
UIKit Graphic: This supports the creation of designing images and animating of view content.
Core Graphics Framework: This is the native drawing engine for iOS apps, and it supports both 2-D vector and image-based rendering.
Core Animation Framework: The app’s animation experience is enhanced with the Core Animation technology.
The frameworks provided by the Cocoa Touch layer are as follows:
EventKit Framework: The standard system interfaces for viewing and altering calendar-related events using view controllers are shown in this diagram.
GameKit Framework: This enables users to exchange their game-related data on the internet via Game Center.
MapKit Framework: This provides a scrollable map that can be incorporated into the app’s user experience.
This iOS skills matrix is a collection of the skills that an iOS developer should have at various stages on the path to becoming a senior iOS developer. The matrix is detailed enough to understand the bigger picture of the iOS developer’s abilities you’ll need but vague enough to avoid canonizing any one area of knowledge.
In this post, we’ll go through the essential iOS abilities you’ll need to learn if you want to work as an iOS developer or create your own iOS apps.
Step 1: Learn Swift
The ability to program is one of the most important abilities that an iOS app developer must possess. These iOS developer skills can vary greatly based on the abilities you already have, the skills that will be the most effective for you to learn, and even the skills that will support you to pivot your software/app development skills to other ecosystems besides iOS development.
Although various programming abilities may be transferred to iOS development, the best chance is to use programming languages designed specifically for iOS and the Apple ecosystem. Swift is the programming language to focus on if you’re learning to write for the first time or if you want to focus only on iOS and Apple development.
The ideal way to study Swift and the iOS platform is to start with the basics of Swift and progress to advanced concepts and eventually the iOS platform. The thinking behind this approach is that most iOS developers try to learn both Swift and iOS at the same time, but they frequently end up confused and not understanding either.
Step 2: Learn the iOS Platform
Following Swift, the next step is to learn about the enormous iOS platform, which is made up of a variety of design patterns, frameworks, and other technologies. Even if you prefer to build iOS apps using a programming language other than Swift, you still need to understand how the iOS ecosystem works.
Beginning with the fundamentals is the best approach to proceed with whatever you wish to master. You won’t be able to employ more exciting technologies like augmented reality, artificial intelligence, or even game development if you don’t grasp the fundamentals first. More significantly, if you don’t understand the basics, you won’t have the necessary skills to get work or create programs that others want to use.
The following are some of the essentials you will need to learn about the iOS platform:
From an overview perspective, comprehend ‘Apple Developer’ (previously known as the Apple Developer Connection or ADC). Apple Developer is a collection of resources that you need to build applications for iOS, macOS, watchOS, and tvOS.
Learn all about Xcode and Interface Builder. XCode is the integrated development environment (IDE) that you’ll need to develop software for iOS and other Apple software. To operate XCode, you need to have a computer running macOS. Interface Builder is a tool that lets you develop iOS interfaces using a GUI (graphical user interface).
Learning to utilize XCode’s Auto Layout feature will assist you in creating user interfaces for a variety of devices.
Views from tables -“Table views” are an important part of the user experience in iOS apps because they let you handle long-scrolling lists.
Storyboards and containers. Storyboards allow you to define and manage navigation flows made using containers in your iOS app.
Start by getting an overview of the different design tools and models, and you’ll find it easier and more familiar.
Step 3: Broaden your knowledge with key iOS developer skills
After understanding code and the environment that you use to create your iOS applications, it’s time to broaden your knowledge into other fields that will give your apps a professional polish. Understanding these areas will help you advance your skill set.
Therefore, Sosene will suggest the following areas that will have a massive impact on your iOS development journey:
iOS apps and most other modern apps are based on databases to store and retrieve data. Understanding how databases operate (as well as the query languages that are used to manage data) can be useful skills helping you get ahead with iOS development.
The majority of modern iOS apps need data transfer through the internet. Therefore, understanding how the internet operates for an iOS developer is necessitated. Fortunately, iOS makes it simple by offering SDKs with several APIs for doing network queries. You also need to learn about the DNS system, URLs, and other general networking principles in addition to these APIs.
Get Started on Your iOS Developer Career
It’s not an easy task to become an iOS developer. It takes time, determination, and patience to become proficient in the profession. Fortunately, there are several tools available, including training classes, to assist you in becoming the developer you desire. The iOS Developer Certification Training from Simplilearn is an excellent solution for demonstrating your skills to potential employers. If you spend your time learning about the iOS developer skills listed above, you will achieve the expected results and meet the standards of an iOS developer.
