Courses
1392 hands-on courses across every major language, framework, and discipline.
Testing & TDD in Swift
Ship reliable Swift: unit and integration tests, mocking, and test-driven development workflows.
Data Structures & Algorithms in Swift
Implement and apply the essential data structures and algorithms in Swift, with complexity analysis and interview-style problems.
Design Patterns in Swift
Apply battle-tested design patterns in Swift to write flexible, maintainable, and extensible software.
High-Performance Swift
Make Swift fast: profiling, memory, algorithmic improvements, and the optimization techniques that matter in production.
Swift by Building Projects
Learn Swift by shipping real projects. Each one adds a new skill and something concrete to your portfolio.
Swift Technical Interview Prep
Prepare for Swift interviews: language deep-dives, common questions, coding challenges, and how to stand out.
Idiomatic Swift & Best Practices
Write Swift the way experts do: idioms, conventions, anti-patterns to avoid, and production-grade best practices.
Kotlin Foundations
Start Kotlin from zero. Set up your environment, learn the core syntax, and write your first working programs with confidence.
Core Kotlin
Go beyond the basics of Kotlin: data types, collections, error handling, and the standard library you reach for every day.
Intermediate Kotlin
Level up your Kotlin. Write idiomatic, well-structured code and solve real problems with the right tools and patterns.
Advanced Kotlin
Master advanced Kotlin: deep language features, metaprogramming, internals, and the techniques senior engineers rely on.
Object-Oriented Programming in Kotlin
Design with objects in Kotlin: classes, inheritance, composition, and SOLID principles for maintainable systems.
Functional Programming in Kotlin
Apply functional techniques in Kotlin: pure functions, immutability, higher-order functions, and composition.
Concurrency & Parallelism in Kotlin
Write fast, correct concurrent Kotlin: threads, async, synchronization, and avoiding race conditions and deadlocks.
