How to hire an iOS app engineer? Skills to look for, interview questions, and more

iOS app development has revolutionized the way we interact with mobile devices, offering a seamless and intuitive user experience.iOS app development primarily relies on the Swift programming language, known for its modern syntax, type safety, and extensive standard library. With access to powerful frameworks like UIKit, CoreData, and SwiftUI, iOS app engineers can create visually stunning and feature-rich applications that integrate smoothly with the iOS ecosystem.

Hiring a developer is easy, but hiring an iOS app developer with adequate skills and experience is challenging as many companies are competing to hire top iOS app engineers from a limited talent pool.
We're here to assist all employers who choose to hire top iOS app engineers on their own. Hiring a developer requires a fair amount of software development experience in general. However, if you're a non-technical manager interested in learning more about how to hire a skilled iOS app engineer, we've put up an excellent resource for you.

Skills to look for when you hire top iOS app engineers

To hire the best iOS app programmers, you must evaluate them for the following skills:

1. Proficiency in Swift 3.0 and above

Developed by Apple, Swift is the most popular global language to develop iOS mobile apps. Hire top iOS engineers who are familiar with core features such as syntax, Objective-C interoperability, inheritance, classes and initialization, and switch statements. Find a candidate who is familiar with core Swift. From wireframing app screens and software planning to user interface (UI) design, coding, integration, testing, and submission to the App Store, developers proficient in Swift are an integral part of your project.

2. Knowledge of spatial reasoning

Proficiency in spatial reasoning is crucial when hiring top iOS engineers. Understanding spatial concepts allows developers to create applications that cater to user preferences and behaviors. By considering the user's perspective, developers can design user-friendly interfaces and deliver exceptional user experiences. A skilled iOS engineer with spatial reasoning skills can effectively optimize app convenience and meaning. Ensuring candidates possess these fundamental skills and familiarity with key app features is essential to building successful and impactful iOS applications.

3. Knowledge of databases

iOS app engineers should have knowledge of databases as it allows them to efficiently handle data storage, retrieval, and manipulation within their applications. Understanding databases enables developers to design optimized data models, execute database queries, ensure data integrity, and implement efficient data access patterns. This knowledge empowers developers to build robust and scalable applications that effectively leverage the power of databases for data-driven functionality and performance.

4. Proficiency in Objective-C

Apple used this language to develop iOS mobile applications. For an iOS developer, understanding the details of Objective-C is paramount. However, experienced iOS app developers need to be familiar with both Objective-C and Swift programming languages ​​and understand that Swift is the future of iOS development.

5. Knowledge of code versioning tools

Software development is incomplete without knowledge of code version control tools. Several code version control tools such as Git, SVN, Mercurial, etc., can help developers to keep track of all their coding changes. Developers with a good knowledge of such platforms can work efficiently on any project.

6. Familiarity with iOS frameworks

Frameworks help you build efficient mobile applications. Several iOS frameworks and libraries such as SwiftUI, Quartz Core, Realm, and RxSwift can help improve the performance of your application. In addition to these frameworks, when hiring a remote iOS app developer, look for candidates for sufficient knowledge of Xcode, the most widely used integrated development environment (IDE) to help develop iOS applications.

Top interview questions to hire iOS app engineers.

Whether you're an IT recruiter or a project manager, you know that finding top developers is critical to the success of your project. Here are some sample interview questions to use when hiring a top iOS app engineer to work on your online applications.

SBJson framework is a JSON framework that is supported by iOS. It is a lightweight data exchange format that is easy to read and write for both humans and computers.

On single-core processors, concurrency is achieved by context switching using time-division multiplexing, which switches threads fast enough to provide multitasking (single-core multitasking looks seamless and modifies to the user, which is fast enough for both processes to appear)

  • A bundle ID uniquely identifies an application within the Apple ecosystem. This means that no two applications can have the same bundle ID. To avoid conflicts, Apple recommends developers use the reverse domain name notation when choosing the bundle ID for their application.
  • The app ID represents one or more applications in the Apple system. It consists of two components: the team ID and the bundle ID search string.

The UIKit class should only be used in the main thread of your application.

Note: UIResponder-derived classes and classes that interact with the application's user interface must be used from the application's main thread.

Core Data is the framework used to manage model layer objects in your application. It provides a general, automated solution for standard object lifecycle and object graph management tasks, including persistence.
