What is the pathway to becoming a Senior iOS Engineer?

Becoming a Senior iOS Developer is contingent upon demonstrating a comprehensive understanding of a variety of hard skills such as ideation, market research, design fundamentals, and most significantly, coding. Additionally, the ideal Senior iOS Developer should have expertise in user testing, compliance, and App Store submission. While these skills may seem simple, they require focused study to master. In addition to technical skills, a well-rounded set of soft skills is also crucial for a Senior iOS Developer to be competitive in the job market. Gaining these soft skills may take some time, but they can greatly benefit individuals in various industries. Here are six strategies to help secure a position as a Senior iOS Developer:

  • Acquire a firm grasp of the basics of iOS programming.
  • Join an iOS developer training program.
  • Master the fundamental programming languages.
  • Develop your own project to hone your iOS programming skills.
  • Refine your soft skills.
  • Build an iOS developer portfolio to showcase at your workplace.

Requirements for a Senior iOS Engineer

The initial phase involves mastering the fundamental skills necessary to secure a well-compensated remote position as a Senior iOS Developer.

  1. Swift

    Swift, Apple’s programming language is an indispensable tool for individuals seeking to develop applications for iOS. As the preferred language for all future iOS development, aspiring developers must grasp the basics of Swift. While mastery of every aspect of the language is not requisite for working as a junior iOS developer, developers should acquaint themselves with Swift’s essential syntax, optionals, flow control statements like if and switch statements, inheritance and class initialization, error handling, and interoperability with Objective-C. These are the fundamentals of the language that establish a robust foundation for beginners.
  2. Spatial Reasoning

    To create successful applications for mobile devices, developers must comprehend the diverse kinds of inputs and controls available for different platforms and understand the spatial connections between objects in three-dimensional spaces. To accomplish this, they must be well-versed with the devices on which the software is created and capable of envisioning how users will engage with the application. While some individuals may possess a natural inclination for this, it is a skill that can be gained through practice and experience.
  3. Design Principles

    Apple’s iOS apps are revered for their user-friendliness, which is accomplished by adhering to Apple’s design guidelines. To create apps that are easy to use, understanding of the design patterns is indispensable. With our iOS Developer Nanodegree program, you will acquire the necessary skills and knowledge to develop iOS applications, including expertise in Swift programming language, the UIKit front-end framework for crafting advanced and rapid web interfaces, Apple’s Grand Central Dispatch and network requirements (GCD), basics of persistence, iOS File System, and sandbox.
  4. Collaboration

    It is nearly impossible to envision an app on your phone that does not rely on the internet in some form. This illustrates the significant role that networking plays in app development. To be able to receive and transmit data from the network, it is crucial to understand and employ the JSON format, which means JavaScript Object Notation. Although this format may seem complicated at first, it is actually a simple and widely-used format.
  5. Essential Knowledge

    One of our Subject Matter Experts recently articulated that learning Core Data is comparable to working out: the initial days may be arduous, but after two weeks, it becomes difficult to imagine life without it. Essentially based on Core Data, Apple’s persistent foundation is critical to the effective storage and retrieval of data on Apple devices. Without Core Data, it would be similar to the early days of video games, wherein the user had to complete the entire game in one sitting, without the option of saving their progress. Therefore, Core Data serves as the bedrock of data storage on Apple devices.
  6. Grand Central Dispatch

    Grand Central Dispatch (GCD), commonly known as Grand Central Terminal, offers an efficient method of introducing concurrency to programs, enabling multiple processes to run concurrently with ease. Why is this significant? Our apps frequently require performing multiple tasks simultaneously, such as obtaining data from the internet, displaying information on the screen, processing user touch inputs, and many more. If all of these processes were to run together, it would overload the user’s device, causing it to slow down or even crash.
