how to hire iOS developers

However, developing a feature-rich, modern, scalable and secure iOS application is not an easy task. It requires a lot of effort, time, patience, and technical expertise. By hiring a skilled iOS developer or a development team, you can build highly innovative iOS applications with splendid features and unique functionality that customers expect. 

If you are planning to start a new iOS app development project, you need to focus on the most important aspect of building an iOS application. And that is hiring iOS app developers with deep knowledge of iOS programming languages, frameworks, tools, and processes.

In today’s post, I will discuss the important skills to look for when hiring iOS app developers and the best ways to hire iOS professionals for your project. Let us understand the required skills first. 

Must-Have Technical Skills of iOS App Developers

The modern-day realm of iOS app development is evolving with advanced technologies and powerful tools used in iOS product development. Apple launches new products, frameworks, and versions every year. Hence, the ideal iOS app developer must have a thorough knowledge of the fundamentals, a proper understanding of the iOS ecosystem, experience, and a passion for learning new things that rise to popularity. 

However, every project is unique and has different requirements. You need to be specific with your project scope, functionalities, integrations, performance, security, time frames, so on and so forth. Not to forget, every project has different challenges that are addressable with specific tools or technologies. Below is a list of must-have technical skills which you can expect in every iOS developer:

1 Xcode IDE Experience

Using Xcode, developers can build universal iOS applications for several Apple devices like iOS, tvOS, macOS, and watchOS. Combined with Cocoa Touch frameworks and Cocoa, it helps to deliver unique applications that offer a delightful user experience. Hence, this is one of the primary and most important iOS development skills you must look for in any iOS developer.

2 Language Proficiency – Swift/Objective-C

To develop native iOS apps, businesses need to use either Swift or Objective-C programming language. One should be familiar with any of these programming languages to support some legacy applications. Furthermore, iOS developers must have profound knowledge of functionalities of Swift such as Syntax, classes, switch statements, inheritance, Objective-C Interoperability, and Initialization.

3 Understanding of Apple Human Interface Guidelines

It is best to hire iOS developers with capabilities to contribute to the app’s UI/UX design elements by strictly adhering to Apple’s design guidelines. In order to build highly intuitive iOS applications, a developer must have skills in styling standard UIKit elements, integrating design assets, and creating custom controls to enhance the look and feel of the app. In-depth knowledge of Auto layout is also a must for developers as it allows to create a UI by establishing relationships between various elements. 

4 Experience in integrating API and third-party libraries

To speed up the development cycle, it is important to take advantage of third-party libraries. And iOS developers must know about integrating APIs and third-party libraries into specific Xcode projects using the Swift Package Manager or Cocoapods.

5 Sufficient Knowledge of Databases like Core Data or Realm

Application effectiveness relies upon the database as the app operation is related to the overall performance, which includes uploading, storing, searching, loading, and filtering data. Businesses, as well as developers, need to store and safeguard their users’ data with a proper backup. To carry out these operations, developers must have a robust knowledge of databases. Some popular databases like Core Data, Realm, SQLite, etc., help developers store or retrieve data on Apple devices in an object-oriented way. Hence, iOS developers need to sharpen their skills on the most used databases. 

6 Proficiency in Grand Central Dispatch

To give users a smooth experience, Grand Central Dispatch (GCD) allows performing many tasks concurrently on Apple devices, such as displaying data on the screen, reading human touch inputs, pulling data from the internet, and many more. And hence, this is a must-have skill for any iOS developer. 

7 Source Control and other team tools

Multiple developers write, submit, change or update their code in a single project several times. And developers must be able to manage and store their code. Keeping control of changes in the source code helps developers resolve conflicts that occur during the source integration. This is one of the essential skills in this list. iOS experts must be well acquainted with source control tools such as Git, SVN, Mercurial, etc. that help them to collaborate with other team members and streamline workflows. 

8 Spatial Reasoning

One of the main prerequisites of iOS app development is thinking from an end-user perspective and developing applications accordingly. This means a developer must be able to design an intuitive user interface, features, and functionality that users look for. This requires the ability to visualize spatial relationships between objects when designing apps for multiple devices. 

9 Non-technical and Soft Skills

Developers have to deal with multiple things simultaneously apart from coding while working with a team of developers and clients. To maximize professional growth and streamline workflow, iOS developers must have soft skills such as communication, teamwork, creativity, problem-solving, dedication, etc. 

Besides the above-mentioned skills, iOS developers must have other important technical skills such as knowledge of RESTful APIs and APIs like Cocoa Touch, UIKit and Swift UI, knowledge of storyboards, table views, memory management, and unit testing. To keep with the latest market trends and deliver AR-based immersive digital experiences to users, they must be able to master new tools or skills like AI algorithm integration, ARKit, and Reality Kit.
