Objective-C is the primary programming language used for iOS app development. Hiring top Objective-C developers with deep knowledge of the language and its frameworks is essential. A senior Objective-C developer or a senior software engineer with professional experience in mobile app development and object-oriented programming concepts can lead the outcome of your app project.
In this article, we will provide you with a better understanding of how to hire Objective-C developers effectively, considering the latest trends and the challenging tasks that come with mobile app development. We will cover everything from the hiring process to the technical skills and experience required for the right Objective-C developer.
What to look for when hiring Objective-C Developers
Objective-C is a powerful and versatile programming language widely used in developing various applications. When hiring Objective-C developers, looking for specific skills and qualities is important to ensure you hire the right candidate for your needs. Here are some key factors to consider when hiring Objective-C developers:
Technical skills
Technical skills are crucial when it comes to hiring Objective-C developers. The candidates should have a strong understanding of the Objective-C programming language and be able to write efficient, clean, and well-documented code. They should be familiar with various Objective-C libraries and frameworks such as Core Foundation, Core Data, and UIKit.
Additionally, they should have experience with memory management, data structures, algorithms, and multithreading. A good Objective-C developer should also have a strong understanding of the iOS operating system and be able to work with Apple's Xcode development environment.
Communication skills
While technical skills are necessary, it is also essential to consider the communication skills of Objective-C developers. They should be able to communicate effectively with other team members, including non-technical stakeholders, to understand their requirements and explain technical concepts clearly and concisely.
They should also be able to work collaboratively with other developers, designers, and testers to ensure that the final product is of the highest quality. Good communication skills are also essential for regular updates on the project's progress, discussing issues, and seeking stakeholder feedback.
Familiarity with design patterns and best practices
A good Objective-C developer should be familiar with various design patterns and best practices in software development. This includes understanding how to design scalable and maintainable code, following coding standards and guidelines, and writing clean and organized code.
They should also be familiar with test-driven development (TDD) and continuous integration (CI) practices, essential for ensuring code quality and detecting issues early in development. Additionally, knowledge of Object-Oriented Programming (OOP) and Model-View-Controller (MVC) architecture is essential for developing robust and scalable iOS applications.
Experience with mobile app development
When hiring Objective-C developers, it is essential to consider their experience with mobile app development. They should have experience developing and publishing iOS applications to the App Store, with a portfolio of apps demonstrating their skills and expertise.
They should also be familiar with the latest trends and technologies in mobile app development, such as augmented reality, machine learning, and cloud services. This experience is important for ensuring that the final product is user-friendly, functional, and meets the needs of your target audience.
Problem-solving skills
Objective-C developers should have strong problem-solving skills, which are essential for troubleshooting issues arising during the development process. 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.
