The rise of Artificial Intelligence is no longer a distant wave on the horizon—it is here, reshaping the tech industry from within. One of the earliest and most profound effects is already being felt by those entering the field for the first time. Junior iOS Developer roles, once a traditional stepping stone into mobile development, are rapidly disappearing. The reason? Companies are quickly discovering that AI-powered coding tools can perform many of the same functions expected from junior developers—without the training, without the mistakes, and without the mentorship requirements that drain valuable team resources.
This isn't a prediction. It's a shift already in motion. Senior developers are leaning heavily on tools like AI-assisted code completion, bug detection, and architectural scaffolding generators. These tools not only increase productivity but also diminish the reliance on junior staff for simple, repetitive, or instructional tasks. In turn, companies are reevaluating their hiring strategies. The traditional model—hire a junior, invest time mentoring, and reap the benefits later—is being replaced with: use AI, ship faster, cut overhead. For businesses, it’s a simple economic decision. But for new developers? It’s a massive barrier to entry.
The Junior Role
The uncomfortable truth is that the support structure around junior roles is breaking down. Time spent mentoring, pair programming, or reviewing beginner code is increasingly viewed as an avoidable cost. With artificial intelligence stepping in to assist mid-level and senior developers, the drain that juniors place on team velocity becomes more visible to upper management. And when the alternative is a stable, ever-learning AI assistant, the junior’s role becomes harder to justify.
So where does this leave the beginner? It creates an urgent imperative: adapt or be left behind. The landscape is no longer forgiving to those who simply want to ‘learn on the job.’ The only route left is to learn before the job begins—to demonstrate mastery before a foot is ever in the door. For iOS development, this means one thing above all else: learn the Swift programming language. Not SwiftUI. Not Combine or any trendy framework that may or may not be in use at the next company. Those can be picked up later. What absolutely cannot be picked up later is the foundational understanding of the Swift language itself.
Swift is the backbone of iOS development. Without it, a beginner is simply unhirable. With it, they become a strong candidate—someone worth mentoring, someone who contributes value from day one, someone who gets hired despite the rise of AI.
The Solution
The solution is refreshingly simple. Focus every minute of your learning on becoming fluent in Swift. Not just reading it. Not just watching tutorials. Write Swift code. Build logic. Apply architecture patterns using pure Swift. Learn how memory works. Understand value types vs. reference types. Learn protocols, structs, enums, and error handling as second nature. That is how you beat the AI era at its own game.
If you are a new developer looking to break into iOS in 2025 and beyond, don’t spread yourself thin across tools and frameworks. Make yourself unignorable by becoming the person who knows Swift better than any AI can fake. Because in a world where AI threatens to replace juniors, the only juniors who survive are those who rise above. And Swift is the only path forward.
The Thing To Take Away
Start learning the Swift programming language and the most commonly used language features. With this skillset you'll be able to showcase your worth in an interview and prove you'll become a valuable contributing member of the team.

Tips to Sky rocket Your Swift Career 🚀
Focus on learning the Swift language itself. Most team members start their learning journey by studying Xcode and building apps. It's a lot of information and plenty to get confused about. Most of your colleagues will have many gaps in knowledge that affect their every-day anxiety with completing tasks and having it reviewed by others. Instead, why not become the one of the reviewers? Our advice is to stand out in the tech industry and if you want to stand out I would suggest becoming very knowledgable about the language itself; Every single developer will be using it and they will all be competing over Architecture and not the best use of language features. Armed with an incredible understanding of the language you will have the confidence in knowing you can maintain any existing product on the market.
Gather "Career Things" like they were collectibles in a game. This easy-to-remember and rather broad term is a great bit of advice. Too many engineers let the months go by without really taking on board many exciting projects or doing anything that wows any one. This is a terrible idea in every way. Stand out. Be the best at something (like understanding the language). When you change positions and apply to a different company you will have an interview and they'll grill you with many questions. The main bits to know are these; Your CV gets you the interview. You display your worth in the interview.
Your CV gets you the interview: Your short 2 page bullet-pointed CV is simply a list of amazing things you did to improve the team, the social element, the code quality, the income, how you increased user retention, how you added a successful feature and improved the app. You must collect career things.
You display worth in the interview: In the interview you want to fill the hour with saying similar phrases non-stop to "I was able to tweak the values and affect the income of the product simply by reducing the friction of the onboarding and providing a more seamless and pleasant user experience for the user. We now have only a 14% drop compared to most companies that have around 30% typically." Notice how you use "we" when referring to your current company in interviews. To simplify the phrase just-used, "I helped my company move forward. I improved the product, which led to an increased user experience and ultimately more profits for the company. I am a team player and I will improve your company at every opportunity possible."
Become confident in Interviews. You are now a talented Swift engineer who understands the Swift language and has a list of successful results you can pull out of the bag and discuss and any interview. You are constantly and infinitely talking about specifics of the Swift language and how cool and useful it is. You are stacking up one example after another of how you affected the results of the team and the company. You are great at telling these stories. The world is your oyster and you can be confident in your abilities as well as your choices in life.
Move company every 2 years. Ask for a £10,000 increase. When you become bored at your current job because you know too much think about moving, upgrading your job title and doubling your annual salary.
Be driven and be proud that you help keep the world moving by maintaining the digital services we all love and are constantly glued to.
