What is an iOS developer? 


An iOS developer is someone who has a deep understanding of the iOS ecosystem, including a deep understanding of how it works on various Apple devices such as the iPad, iPhone, Apple Watch, and Apple TV. In short, they need to understand how to build and configure apps within the iOS environment.

If you do a little research, you'll find the iOS skill matrix, like the one pictured below. The iOS Skill Matrix is a collection of skills that one should have at various levels to become a top iOS developer. The matrix is detailed enough to give you an idea of what iOS developer skills you need but, at the same time, is vague enough to avoid defining any specific knowledge area. In other words, it should only be used as a guide to help you find your way. 


In this article, we will go over the main iOS skills that you need to know if you want to become an iOS developer and get a job or power your iOS application. 

 Learn Swift 


One of the most important skills an iOS app developer must have is the ability to program. These iOS developer skills can vary based on the skills you already have, the skills you'll be best suited to learn, and even the skills that can help you transfer your software/app development skills to environments other than development. iOS.

For example, you can develop an iOS application using Java programming skills and use the same Java programming skills to develop for Android, Mac, Linux, and Windows. If you are facing time or budget constraints and hope to soon be able to switch from iOS development to other platforms or environments , Java Exam Prep and Training is a great option to consider. However, if you love software development and have the time and budget, but still expect to want to get into other environments besides iOS, back-end training, in front-end developer training - the end or the full collection may be better choice.

You can, for example, learn how to create an iOS app that runs on Angular, which is part of the MEAN stack. While the various programming skills that can be used for iOS development are transferable, using a programming language intended for iOS and Apple's environment is your best bet. If you are learning to code for the first time or just want to focus on iOS and Apple development, then Swift is the programming language to focus on. The best step to take in learning Swift on the iOS platform is to build a solid foundation, starting with the basics of Swift, and then moving on to advanced concepts and finally the iOS platform. The idea behind this approach is that many iOS developers often try to learn Swift and iOS at the same time, but often get confused and do not understand.

  3. Control flow instructions. Includes for/while loops, if-else and switches 
  4. Format and Interface. Includes structures and calculations, methods, functions, patterns and extensions 
  5. The concept of object-oriented programming. Includes inheritance, classes and polymorphism

Understanding these areas will allow you to increase your skill level and become an expert. There are many areas of knowledge that you can draw from. Check out the iOS skills matrix above to get an idea of what you need to know. Additionally, understanding these knowledge areas will greatly impact your iOS development journey: 


Data set 


iOS apps and many other modern apps rely on databases to store and retrieve data. Understanding how databases work (and the query language used to manipulate data) can be a valuable skill, helping you progress through iOS development. Network 


Most modern iOS apps require data to travel back and forth over the Internet. This means that an iOS developer must understand how the Internet works. Fortunately, iOS makes it easy by providing an SDK that provides several APIs for making network requests. In addition to these APIs, you'll also need to understand DNS, URLs, and other general networking concepts.
