Introduction
The mobile market is still growing and will continue to grow. This conclusion I made from different reports and trends of global research companies. Nowadays, I can not imagine myself without mobile applications. Fitness, banking, utilities, and many other services are managed by mobile applications. So, these make it a great time to enter the field as a junior iOS developer for you.
Junior developers can offer cost-effective solutions for companies, which is particularly beneficial for startups and smaller businesses. Often they can bring fresh perspectives and innovative ideas, which can lead to unique and valuable contributions to projects. Overall, the importance of junior iOS developer skills lies in their ability to bring new ideas, cost-effective solutions, and fresh perspectives to the industry, while also providing opportunities for career growth and development.
Programming Language
I remember a time when I had just started my development career and had just learned the Objective-C language. Many friends were skeptical that I had learned Objective-c rather than Swift. It was 2014, and since then, both languages have been used for iOS app development. Swift was very crude then, and most applications were written in Objective-C. Even now, in 2023, I receive offers to write and maintain applications written on Objective-C. But I agree that Swift is today’s primary development language.
The importance of both languages cannot be underestimated. Many existing iOS applications have been developed in Objective-C, and companies need developers who can maintain and update these codebases. Therefore, Objective-C remains relevant today. Swift was designed to be a modern language with modern features, such as type inference, optionals, and closures, that are not available in Objective-C. As a result, Swift allows developers to write code that is more efficient, easier to read, and easier to maintain. Also, Swift and Objective-C are interoperable, which means developers can use both languages in the same project. This allows developers to slowly migrate their Objective-C code to Swift or vice versa, as well as integrate new features using Swift while still maintaining existing Objective-C code. And both Swift and Objective-C have large communities of developers who contribute to open-source libraries, frameworks, and resources.
Sure, they are different, Swift was designed to be a safer language than Objective-C. And Swift is generally considered to be faster than Objective-C. But Objective-C has a steeper learning curve than Swift due to its unique syntax, whereas Swift is designed to be easier for developers to learn and write. Overall, both languages have their strengths and weaknesses, and a good understanding of both can be valuable for developers in the iOS development market. So I suggest you start with Swift and then study Objective-C. Scoring ahead in your career, knowledge of Objective-C is a big plus as a senior iOS developer.
UI and UX Design
User Interface and User Experience design are critical components of any mobile app development process. UI design focuses on the look and feel of the app, while UX design focuses on the overall user experience. Both of these elements are important because they can significantly impact the user’s perception of the app and ultimately determine whether they continue to use it or not.
A well-designed UI can make an app look visually appealing, consistent, and easy to use. A good UI design should have a logical layout, clear and concise labels, and effective use of colors and typography. On the other hand, a good UX design focuses on the overall user experience, including the ease of use and the efficiency of the app. A well-designed UX can help users to quickly and easily complete tasks within the app, making it more likely that they will continue to use it. A good UX design should consider factors such as user flow, task completion, and user feedback.
Junior developers should have a basic understanding of design principles because it can help them to better understand the user’s needs and expectations. By understanding the principles of UI and UX design, junior developers can create more effective and user-friendly apps. Additionally, having a basic understanding of design principles can help junior developers to communicate more effectively with designers and other members of the development team. At the end of this story, you will find useful links about UI/UX design and also other links.
Git and Version Control
To be honest with you I can not even imagine my developer life without Git. It’s hard to count how many times Git has saved me and made my life easier. Git is a distributed version control system that is widely used in software development projects. It allows developers to keep track of changes made to the codebase, collaborate with other developers, and maintain different versions of the software.
It has many reasons to use version control, and you will understand it now or through the time of your career path. But here are some of them:
- Backup and Recovery: provides a backup of the codebase, ensuring that you can recover your work in case of a catastrophic failure. Believe me, when I was a junior developer, I did a lot of mistakes.
- Collaboration: enables multiple developers to work on the same codebase and keep track of each other’s changes.
- Code Management: allows developers to manage different versions of the codebase, track changes made over time, and revert to previous versions if needed. This is particularly useful when working on complex projects where mistakes can easily be made.
- Continuous Integration and Deployment: Version control is an important part of the continuous integration and deployment process. It allows developers to automate the build, test, and deployment of their code, ensuring that changes are tested thoroughly before being deployed. But do not focus on this, I think this skill is for an advanced intermediate or senior position. But
- Code Reviews: Git provides a platform for code reviews, where developers can share their code with their peers and receive feedback on their work. This helps to improve the quality of the codebase and ensure that best practices are followed.
It is crucial for junior developers to have a basic understanding of version control because it is a fundamental part of software development. Without knowledge of version control, developers may struggle to collaborate with their peers, manage code effectively, and ensure that their work is properly backed up. Additionally, most software development teams use Git as their primary version control system, so familiarity with Git is a valuable skill for junior developers to have.
Collaboration and communication
Collaboration and communication are crucial in software development. In a team, members work together towards a common goal, and effective communication ensures that everyone understands their role and the requirements of the project. As a junior developer, it’s essential to have strong communication and collaboration skills to work effectively in a team and deliver projects on time.
Through my experience, I can tell you that collaboration is not only about working together. It involves sharing knowledge, ideas, and expertise to achieve common goals. In collaboration, you can find a better solution, learn, grow, and improve your skills with knowledge. As a junior developer, you can learn a lot from more experienced team members, and by working collaboratively, you can contribute to the team’s success.
Communication is essential to ensure that everyone is on the same page. Miscommunication can lead to misunderstandings, missed deadlines, and costly mistakes. As a junior developer, you should be able to communicate your ideas clearly and concisely, both verbally and in writing. By improving your communication skills, you can build stronger relationships with your team members and work more effectively towards common goals. I worked in different teams around the world. And in the beginning, I had some problems. So, to improve your communication skill I advise you to practice active listening, maintain eye contact, avoid interrupting, and ask questions to clarify messages. Also, reading and writing regularly can help improve your vocabulary and grammar. Make it a habit, because it requires time and practice.
Conclusion
Junior iOS developers must possess essential skills to excel in today’s competitive market. These skills include knowledge of Swift, a better with Objective-C, an understanding of UI and UX design principles, familiarity with Git and version control, testing and debugging skills, and strong communication and collaboration skills.
Having a strong foundation in these skills can greatly benefit you as a junior iOS developer. Also, with these skills, you can create more efficient and effective applications, collaborate better with team members, and ensure the best user experience for your audience.
