They should be able to identify the root cause of the problem, propose and implement effective solutions, and test the key to ensure that it works as expected.

Additionally, they should be able to anticipate potential issues and plan accordingly to avoid or mitigate them. Good problem-solving skills are also essential for working collaboratively with other team members to find creative solutions to complex challenges.

In conclusion, when hiring Objective-C developers, it is essential to consider their technical skills, communication skills, familiarity with design patterns and best practices, experience with mobile app development, and problem-solving skills. These qualities will help ensure that you hire the right candidate for your needs and develop high-quality iOS applications that meet the needs of your target audience.

Top 5 Objective-C Interview Questions

When hiring Objective-C developers, asking the right interview questions to assess their technical skills and knowledge is crucial. Here are the top five technical Objective-C interview questions that you can ask :

Can you explain the difference between a structure and a union in Objective-C?

This question estimates the candidate's understanding of the basic data structures in the Objective-C. A structure is a user-defined data type that groups related data of different types. On the other hand, a union is also a user-defined data type that allows storing various data types in the exact memory location. You can learn from the answer how well the candidate understands the differences and similarities between these two data structures.

What is the significance of the 'volatile' keyword in Objective-C?

The 'volatile' keyword indicates to the compiler that external sources can change the value of a variable. You should ask this question to assess if the candidate knows how to use this keyword in their code. Additionally, the answer can provide insight into the candidate's low-level programming knowledge and experience working with hardware devices.

What is the difference between call by value and call by reference in Objective-C?

This question tests the candidate's definition of function-calling conventions in the Objective-C. Call by value passes the value of the argument to the function, while call by reference passes a reference to the memory location of the argument. You can learn from the answer whether the candidate is familiar with these concepts and whether they understand how to use them in their code.

How do you debug a segmentation fault error in Objective-C?

Segmentation faults occur when a program tries to access a memory location it is not allowed to access. This question considers the candidate's debugging skills and how well they can troubleshoot errors in their code. The answer should include steps such as using a debugger, analyzing the core dump file, and reviewing the code to identify the source of the error.

How do you dynamically allocate memory in Objective-C?

Dynamic memory allocation is a crucial concept in Objective-C. This question tests the candidate's understanding of allocating and deallocating memory using functions such as malloc() and free(). The answer can provide insight into the candidate's memory management knowledge and experience working with large data structures.

In conclusion, the above interview questions can help you reckon the technical skills of a Objective-C developer. It is crucial to ask the right questions to ensure the candidate has the knowledge and experience to perform the job effectively.
