IQ – quiz for iOS vs AI App Localization: xcstrings Uso & Estadísticas

Multithreading, memory, architecture. New AI mode based on Foundation Models, hardcore challenges, and global rankings. Are you preparing for a Middle/Senior interview or just want to keep your brain in shape? I've collected and packaged everything that's asked in technical interviews into one app and added a powerful task generation engine. What's inside? Fundamentals: hardcore questions on topics to think about. Multithreading: GCD, Operations, Actors, data races. Memory management: ARC subtleties, retain cycles, and much more. Algorithms: From Big O to trees and graphs. Architectures: Breaking down MVC, MVVM, VIPER, TCA. Compiler and runtime: How Swift works under the hood. Infinite task generator The main feature of the update is Dynamic Mode. The app generates unique cases and questions in real time. This allows you to not only memorize the correct answer, but also to truly understand how a particular technology works by encountering new formulations each time. Training modes Time sprint: Live coding stress simulation. Learn to think fast. One mistake: “First mistake” mode. For those who are confident they know the documentation by heart. Progress and Rating Detailed statistics will show your weak areas (for example, if you are good at UI but struggle with algorithms). And the global leaderboard will help you compare your grade with other developers in the community. Adjust the difficulty to suit yourself, choose topics, and download skills.
