## What is DevPrep?

Ace your iOS developer interview and keep your skills sharp.

Hundreds of questions and hands-on coding tasks across 21 topics — the base is updated regularly: Swift, SwiftUI, Swift Concurrency (async/await, actors), Combine, memory & ARC, multithreading & GCD, UIKit, Auto Layout, architecture (MVVM, VIPER, Clean), Objective-C, algorithms & data structures, networking, testing and soft skills.

WHAT'S INSIDE
• Apple-docs-style answers with syntax-highlighted code
• Hands-on coding tasks with full solutions: “predict the output”, “find the bug”, “implement it”
• Junior / Middle / Senior and Legacy / Modern level tags — study exactly what you need
• Progress tracking, a “learned” marker, a daily streak and goal
• A spaced-repetition flashcard trainer and a “Hard” deck
• Built-in search and an in-app reader for external materials
• Light and dark themes
• Full Russian & English — switch on the fly
• Works offline
