Are you an iOS developer trying to sharpen your Swift skills and break into top tech companies like Meta, PayPal, or Stripe? Or maybe you're self-taught and frustrated by algorithm tutorials that feel like they're written for computer science majors? This course is built for you.

“LeetCode-Style Problems for Fintech and Social Media Apps” is a practical, challenge-driven course that combines interview-level coding exercises with real-world Swift scenarios pulled from fintech and social media development.

We’ve designed each module to simulate real engineering problems — like tracking user logins, identifying the most active accounts, grouping users into friend circles, and calculating the busiest times in an app. These are exactly the types of problems you’ll face in interviews, or when working on scalable iOS products.

But unlike other courses, we don’t throw CS jargon at you and expect it to make sense.

This course breaks down topics like graph traversal, union-find, trees, and sliding windows in plain English.

No theory-dumping. No academic fluff. Just clear, example-driven teaching and practical applications.

You’ll learn:

How to use Depth-First Search (DFS) and Breadth-First Search (BFS) in social graphs without memorizing academic patterns
When and how to apply sliding window logic to time-based app data
What Union-Find really is, and how it’s used to group related users — without requiring a CS degree to follow along
How to count frequency, detect duplicates, and sort custom logic efficiently with Swift’s built-in tools
How to write clean Swift code that passes interviews and makes sense to other developers

This course includes:

Real-world LeetCode-style challenges
Guided coding walkthroughs
Clear visual breakdowns of data structures like trees, graphs, and hash maps
Optimized Swift solutions with explanations you can actually understand

Whether you’re prepping for a coding interview, trying to become a more confident Swift developer, or applying your skills to real product logic, this course will help you think like a problem-solver — not just a coder.

No computer science background required. Just bring your curiosity, your laptop, and a desire to actually understand the logic behind professional Swift development.
