Objective-C test

The Objective-C test evaluates a candidate's proficiency in this programming language, commonly used for macOS and iOS application development. The test covers essential object-oriented programming (OOP) concepts such as classes, objects, inheritance, polymorphism, and encapsulation.

Candidates will be assessed on their understanding of Objective-C’s core syntax and structure, including headers, implementation files, and method declarations. It also measures the candidate’s ability to work with memory management concepts like reference counting, autorelease pools, and memory leaks.

The test evaluates familiarity with key frameworks, such as Foundation and UIKit, and how to use classes and methods from these libraries for application development. Additionally, candidates will be tested on debugging, error handling, and performance optimization.

Knowledge of design patterns like MVC (Model-View-Controller) is key, as candidates will need to demonstrate the ability to implement these patterns effectively. Familiarity with interacting with other technologies, such as APIs, databases, and third-party libraries, is essential.

The test also includes problem-solving scenarios, requiring candidates to write clean, efficient, and maintainable code. It assesses both theoretical knowledge and practical skills, along with understanding how Objective-C integrates with the broader Apple ecosystem, including Swift.
