7 iOS Development Skills | 2021

We’re going to discuss 7 skills you need for iOS development. We are gonna roll through these skills and give you a little bit of backstory, a little bit of knowledge on each one. Do more research and learn these skills if you plan to become an iOS developer.

I know there’s gonna be people saying you missed this and that, there’s so much more to iOS development.

You can download iOS apps for free with AppValley.

To solve for iOS development, these are the 7 things that I just think that you need. Let’s get started.

iOS-Development-Skills
iOS Development Skills

Swift

Skill Number 1 is Swift. Swift is the language of iOS development and macOS development now.

It was used to be objective-C. Many applications are still built with Objective-C.

If you go work in iOS development, you may need to work with Objective-C but you should learn Swift first.

It’s easier so when you’re learning an easier language, it’s easier to stick with it, especially if you’re just starting out.

Swift is one of the easiest I’ve ever learned.

Objective-C is a little bit more difficult but if you know Swift at least, at a level, you know where you’re getting hired by other companies. You should be able to work with Objective-C.

You won’t need to know off the top of your head every little thing about Swift or any programming language for that matter.

You should understand the basic syntax, optionals, control, flow, classes, also the initialization, and handling of variables.

There are many different places to learn Swift.

You can use Apple’s own Swift book. Swift is a newer language so the syntax and particular things changed over time in that book. It’s updated over time.

You can invest in something like a whole iOS development course on Udacity.

You can have a membership to Pluralsight.

Spatial Reasoning

Skill number two is spatial reasoning. Imagine you or the end-user, want to make sure your buttons are properly laid out. This has a to play into the design and not just user interface but more so user experience.

You have to understand how the user will interact with your application.

When it comes to dealing with spatial reasoning, if you’re developing for iPhones or you’re developing for iOS, you should probably be using or used to using an iPhone.

Spatial-Reasoning

If you’re developing for Android you should be used to using an Android.

I’ve been doing a lot of Android development recently and it’s a little bit different because I’m so used to iPhone.

You must know that how iPhones interact with people because although they’re both mobile phones, you know, there are particular guidelines for iPhones and particular guidelines for Android.

You should know what’s expected in an iOS native application or an Android native application.

Because the user interface and the user experience are slightly different things.

So be a user of the iPhone if you’re going to do iOS development.

Design Guidelines

Skill number three is to understand the design guidelines for iOS because we want you to be familiar with iOS and kind of adhere to more strict design guidelines which we use. It is an MVC Model View controller.

What Model View controller does is basically determines or defines data, how it’s stored how it’s updated and how it’s presented to the user based on user interactions with your application.

Android development will use MVC but they also use MVP.

They use MVC which is the Mount of view model and MVP is Model View Presentation.

App-Design-Guidelines

There are few different design guidelines over there but when it comes to iOS development, we should strictly stick to the MVC Model View controller.

When it comes to design guidelines our delegate pattern is kind of how information is passed among objects in Cocoa.

If you’ve developed an iOS application you know Cocoa. We use it a lot in the notifications part. How do notifications work?

Basically, the delegate pattern is one sender and one receiver of notifications. As you may know that there can be one sender and multiple receivers as well.

Those are just a few points to take note of when it comes to the design guidelines.

Networking

Skill number four is networking. Networking can be interpreted in many different ways but in this scenario, networking is essentially how your app interacts with the web.

A lot of times we’ll be pulling data from the web using APIs.

In order to communicate, we use JSON which stands for JavaScript Object Notation.

So when it comes to working with networking and connecting your application to the web and things of that nature that’s what you need to know.

Networking is a common skill for both Android and iOS development.

Core Data

Skill number five is Core data. Core data is the way you store data on Apple devices.

Basically, if you use an application and you want to come back to that application and you want everything to be saved, core data is used here.

For example, Scores on your game, the things you purchased in your game, and your information to be saved, so maybe you don’t have to log in to Instagram every single time, core data does it all.

Grand Central Dispatch GCD

Skill number 6 is Grand Central Dispatch or GCD.

When you’re creating an app and you don’t know anything about Grand Central Dispatch or you’ve never heard of it at all, it’s easier to accidentally make an application with it than without it.

This is basically allowing your application to run smoothly, faster, and more efficiently.

An app needs to pull data. display information, read inputs from the user, and kind of how they’re interacting with your application all at the same time.

It’s definitely something you need to know about that’s why I added it to these 7 skills for iOS development.

GitHub

GitHub

Now finally skill number seven, You need to get Github in order to show your applications and your work to the world especially if you look for a job whether that be for a company or whether that be for clients.

This is a very good reason to have Github but there’s also something else called Git.

You can either be using Git and/or Github for this.

It is a version control system. You use Git and Github for version control.

If you have a working application and you try to add a feature, your application crashes or you realize that you don’t want a particular feature, you can use a version control system and revert it back to a previous version of that application.

Another example, have you ever had a folder maybe for school, for class whatever in your computer where you have a version one, a version two, a version three and so on that’s essentially a version control.

You have essentially one complete version and version one but then you add into that, you edit that, change that and then you have version two and then you edit that and change it then you have version three so.

When it comes to version control Git and GitHub are gonna be your tools for that.

I think that’s gonna be it for the 7 skills you need for iOS development.

I wanted to get a little bit away from the more basic points and more basic skills and I wanted to address MVC, JSON, GCD, and a few of those things that you should probably know if you’re looking into iOS development.

These are the things you’re going to be running into them one time or another in the field of iOS development.

You can get some useful apps for iOS App dev.
