Qualifications for a Senior iOS Engineer

The first step is to learn the core skills required to get a high-paying remote Senior iOS developer job.

  1. Swift

    Apple’s Swift programming language is an essential tool for anyone looking to develop applications for iOS. As the language of choice for all future iOS development, it is important for aspiring developers to understand the basics of Swift. While it is a powerful language, it is not necessary to know every aspect of it to work as a junior iOS developer. To be successful, developers should become familiar with Swift’s fundamental syntax, optional, flow control such as if and switch statements, inheritance and class initialisation, error handling, and interoperability with Objective-C. These are the building blocks of the language that will provide a strong foundation for those just getting started.
  2. Geographical reasoning

    Developing successful applications for mobile devices requires developers to have an understanding of the different types of inputs and controls available for the various platforms, as well as a comprehension of the spatial relationships between elements in a three-dimensional environment. This necessitates familiarity with the devices that the software is being developed for, as well as the ability to think about how users will interact with the app. While some people may have more of a natural aptitude for this, it is a skill that can be acquired through practice and experience.
  3. Design principles

    Developing successful iOS apps is renowned for their ease of use, due to the adherence to Apple’s design guidelines. To build intuitive applications, familiarity and understanding of the design patterns is essential. With our iOS Developer Nanodegree program, you will gain the necessary knowledge and expertise to develop iOS applications, including Swift programming language, UIKit front-end framework for developing complex and fast web interfaces, Apple’s Grand Central Dispatch and network demands (GCD), and basics of persistence, the iOS File System, and sandbox.
  4. Collaboration

    It is almost impossible to think of an app on your phone that does not rely on the internet in some way, which demonstrates the vital role that networking plays in app development. To be able to transmit and receive data from the network, it is necessary to understand and use the JSON format, which stands for JavaScript Object Notation. This format may initially seem complex, but it is actually quite a simple and widely used format.
  5. Fundamental information

    One of our Subject Matter Experts recently remarked that learning Core Data is akin to working out: the initial days are difficult but after two weeks, it is hard to imagine life without it. Apple’s persistent foundation is essentially based on Core Data, making it imperative for the efficient storage and retrieval of data on Apple devices. Without Core Data, it would be similar to the early days of video games where the user had to complete the entire game in one go, without the option of saving their progress. Core Data is, thus, the cornerstone of data storage on Apple devices.
  6. Grand Central Terminal

    Grand Central Dispatch, more commonly referred to as GCD, provides an effective way to add concurrency to programs, allowing multiple processes to run concurrently with ease. What is the significance of this? Our applications often need to perform a variety of tasks at once such as obtaining data from the Internet, displaying information on the screen, processing user touch inputs, and more. If all of these processes were to run simultaneously, it would place an immense burden on the user’s device, causing it to slow down or even crash.
