He holds a BS in Computer Science from the University of Alabama. In 2017, global app revenue grew by 35% to reach nearly $60 billion, with iOS apps accounting for $38.5 billion of revenue.

There are lots out there, and I really appreciate the fact that the Swift community has such a broad range of people sharing their experience. However, here I’m specifically going to look at resources that are free – places where you can go and learn to build fantastic apps without paying a cent. The sixth big problem folks hit is trying to learn Objective-C. This was Apple’s primary development language before Swift was introduced, and although you’ll find remnants in some old codebases the overwhelming majority of existing code is now Swift, and almost all new code is also Swift. But unless the original course chose a particularly weird topic to cover, you’re probably going to have to learn it eventually and you’re just kind of delaying the inevitable. Even if you just think about the APIs Apple publishes, which are the pieces of code we can use to build our apps, there must be well over a hundred thousand out there.
Since you will be building iOS apps, it’s best to start using and getting comfortable with them. Another thing to consider is the amount of education you’ll be receiving. It’s a four-year degree, meaning you will learn a greater variety of related courses. You’ll also learn more about the theory versus the actual development side of iOS development. Because you receive a more well-rounded education with a four-year degree, you will have a wider range of employment options as compared to the specialized training one receives from being self-taught or coding bootcamp.
Ios Development Languages
Just to be clear, SwiftUI isn’t somehow a replacement for Swift – it’s a framework built on top of Swift that lets us make apps, so you need both Swift and SwiftUI to succeed. The best way to learn iOS app development is to start your own app project. You can try out newly learned things in your own app, and gradually build towards a complete app.
- I’m not saying that you’re the master of Swift but at the end of this lesson, you’ll see how all of your code works together inside of an app.
- There are many databases to choose from when building a mobile app.
- According to Statista, mobile apps will reach $188.9 billion in revenue by 2020, a twofold increase compared to 2016.
- Since you will be building iOS apps, it’s best to start using and getting comfortable with them.
- The best thing you can do right now is to complete as many of the One Day Builds as you can.
Instead, you spend these resources on something you’re 100% committed to. Bring users together in an entirely new way by integrating your apps into FaceTime using SharePlay and the Group Activities API.
Companies Who Use Ios
Every time I learned a new skill, I would encounter something known as “the dip”. The concept of this “dip” was originally introduced to me by Seth Godin. SwiftUI helps you build great looking apps across all Apple platforms with the power of Swift — and as little code as possible. Tracking performance, and measuring what features align with the priorities of your customer’s needs allow you to craft a development roadmap that yields the most success.
You’ll also learn about the properties and methods that live inside your structure. Also, you’ll learn how, depending on where you write your code, the scope of a property or method can change. We’ll start by learning how to preview the app so that we can see what the user interface looks like. Then I’ll demonstrate how to use Xcode to visually construct the user interface, or UI for short.
There are other options too, as I’ve explained in this tutorial. When you’ve finished reading this tutorial, you will have a step-by-step plan for learning how to code. You know exactly what to do, what steps to take, and how to take them. Oh, and you don’t need any coding experience to get started. There are certain tools and coding paradigms every iOS developer should be aware of and you should be aware of how to recognize the developers that have those skills.
Companies would much rather you knew how to use SwiftUI, UIKit, or one of the other big hitters, because in comparison testing as a topic is significantly smaller – there aren’t nearly as many things to learn. Hundreds of thousands of apps have already been written in UIKit, so if you’re joining a company with a large, well-established app you will almost certainly need to write UIKit code to maintain that app. As before, I want to explain each of those in more detail so you can understand why I think they are important – and why I consider them extension skills rather than core skills. But if you’ve worked your way through those skills and want to go further, then there are five extensions skills I would encourage you to learn.
You will start by learning the basics of iOS app development using the Swift programming language and Xcode, Apple’s development environment. You’ll develop your first iOS apps using layouts, views, UIKit, and more. Then, you’ll progress to build more complex and advanced applications, using networking, and Apple’s Grand Central Dispatch and Core Data, and will be ready to publish your capstone project to the App Store. Effective enterprise iOS application development would include a tailored approach to your business model, industry, clients, as well as proper integration into your existing systems and cloud infrastructure.

He’s also the editor of Swift Developer News, the maintainer of the Swift Knowledge Base, and a speaker at Swift events around the world. If you work super hard and get a job after 50 days, that’s fantastic – well done!
What is the best IDE for iOS development?
Xcode is the official IDE of Apple to develop software for macOS, iOS, iPadOS, watchOS, and tvOS. This is the perfect choice to develop apps as it also helps publish the app on the Apple App Store.
I mean really, really bad – many huge apps have hardly any tests at all, and I’ve lost track of how many senior iOS developers I met who are almost proud they never write tests. The third and fourth skills I mentioned were networking and working with data. Compared to Swift and SwiftUI these are a piece of cake, or at least they are at the level you need to be in order to get a junior iOS developer job. If you were applying for a job right now – today – then fine you will probably need to know UIKit, but as you’re reading this article it means you’re much earlier in the process. Yes, UIKit is more popular now, but by the time you finish learning 6, 9, or even 12 months from now, SwiftUI will be the dominant UI framework. SwiftUI works on all of Apple’s platforms, so you can take what you learned on iOS and use it to build a macOS or watchOS app with almost identical code.
You’ve already seen what Swift code for the user interface looks like. In this lesson, you’ll begin to learn how Swift code is used to keep track of the data in your app!.

In the next 14 days, you’ll gain the core skills to build your own simple apps. Learn the basics of Swift, the programming language used to develop iOS apps.
All of this combines together to create a mobile ecosystem that facilitates distributing and monetizing your mobile app, making iOS a great choice for a development platform. It makes sense to build your app to take advantage of this profitable mobile ecosystem, but it’s also an excellent candidate due to how versatile it is with a wide range of devices it supports. IOS is available on iPhone and iPad devices, allowing apps to be accessed on both phones and tablets.
An iOS developer is a developer that is able to build native iOS applications using Apple’s proprietary IDE XCode as well as leveraging the power of programming languages like Swift and/or Objective-C. Trio is staffed with a full-time roster of highly experienced developers who specialize in developing mobile apps on iOS. In this lesson, you’ll learn a new Swift construct that will allow you to write code that says, if this, then that. This easy to use but powerful syntax will allow you to express logic at a whole new level.
