Top 10 Skills To Consider While Hiring iOS Developers

Hire iOS developers

iOS is one of the most popular mobile app development platforms. Ever since its inception, the realm of iOS app development has seen a rapid increase, with over 2.22 million apps available on the iOS app store as of 2021 with iOS developers being some of the most in-demand professionals.

There are various reasons why iOS rose as the most preferred platform for developers across the world. The ease of app development, high-profit potential, unified user interface, and an overall minimalistic appearance to name a few, led to the extensive development of iOS apps. Moreover, with a unified UI, the room for fragmentation problems is limited.

The most important aspect of developing an iOS app is hiring talented iOS developers with a strong background in mobile development.

In this article, we will discuss in detail the top 10 skills you should look for when you hire iOS developers for your team.

Technical skills your iOS developer must possess

Practical knowledge of Swift 3.0

Swift 3.0 is the most popular language for iOS app development.

Swift, an object-oriented programming language, developed by Apple has a simple syntax and is easy to use. It is a robust and intuitive programming language used to create applications for Apple's platforms, including macOS, iOS, watchOS, and tvOS.

Swift is fast, stable, and gives iOS developers the freedom to quickly develop responsive and feature-rich iOS applications. Moreover, it is open-source and quick to learn.

When you hire iOS developers, it is essential for those programmers to have an in-depth knowledge of Swift 3.0. The iOS developers you hire must also have experience in working with the language.

Experience in Xcode IDE

IDE or Integrated Development Environment is one of the primary skills to look for when you want to hire iOS developers.

An IDE contains a set of tools and programming essentials for automation, debugging, programming, interpretation, and compiling to make the process of creating software or mobile apps simple. The resources available in an IDE make development and deployment processes easier for both newly created applications and those already released.

IDE also provides an incredible user experience and reduces development time and cost for iOS app development. Ensure to look for skilled developers in Xcode IDE when you hire iOS developers.

Core Data

Core Data is a framework that eases the development of data-driven applications. It simplifies the management of model objects and their relationships. This relieves the iOS developer of routine tasks associated with object life cycle and graph management.

Core Data significantly decreases the amount of code a developer writes to support the model layer. iOS developers can use Core Data to save application data for offline use, to cache temporary data, and to add undo functionality to an app on a single device. Core Data automatically mirrors the schema to a CloudKit container when syncing across multiple devices in a single iCloud account.

Companies should hire iOS developers who are well versed in using Core Data to build customer-centric applications.

Experience in memory management

Memory refers to the hardware used to store data on your device. The primary short-term memory system in an iPhone or iPad relies on integrated RAM to store data temporarily. The device's operating system determines this allocated memory dynamically. iOS devices are resource-constrained on memory, so managing this memory is very crucial.

Apps get only so much memory access from the system which can cause them to run slower and eventually crash.

An experienced iOS developer understands that the app might stop functioning once it crosses the established per-process limit. This is why it is important to hire iOS developers who are proficient in memory management because it is vital for developing a successful iOS app.

Skilled in source control

Source control is a system management strategy used to track the changes that are made in the source code. This technique helps prevent conflicts between developers who work on the same application. It is an integral part of application development. A hands-on experience with source control helps iOS developers collaborate with one another and streamline the development process. Hire iPhone app developers who are skilled at managing and working in teams.

Experience in unit testing

A unit test is a function that tests how well the app works. Good unit tests are small, fast, and isolated, each one tests just one thing by itself. For example, if you worked on a calculator app and added a feature that calculates the total time spent on activities in your app, you might write one unit test to make sure this new feature works correctly. You’d want to run this new test immediately after building your latest code changes so that you can find any problems as early as possible.

Unit tests can help prevent bugs. They check the functionality of each function in an application by using sets of given inputs and ensuring that they produce the correct outputs.

So, hire iOS developers who are well acquainted with these development skills to aptly test the validity and functionality of the app.

Proficiency in Grand Central Dispatch

iOS applications run many tasks simultaneously, including fetching data from the network, displaying relevant information on the screen, and responding to touch inputs. This can significantly strain the device’s hardware.

Grand Central Dispatch is used in iOS to introduce concurrency and parallelism in the operating system so that heavy computing tasks can be performed in the background without affecting the user experience.

No matter what your requirements are, hire iOS developers who are proficient in GCD. Apps should be concurrently programmed from the developer’s end so as to prevent a crash and slow down of the phone. This improves the user experience.

Spatial reasoning ability

One of the main qualifications for an iOS app developer is spatial reasoning ability. Spatial reasoning is the capacity to understand objects at various scales and to manipulate them mentally. It answers “How will the user utilize this app?” You must hire iOS developers who can the user’s perspective to develop robust and user-friendly apps.

This skill bears significant weight in the developers’ skillset as the developer must consider all the parameters to provide an unparalleled user experience. Make sure that you hire iOS app developers who consider the user’s viewpoint. This will help them design more intuitive interfaces and better functionalities.

UI and UX design experience

UI/ designers, or “user experience design experts,” specialize in the aesthetic elements of an iOS application. They create the look, feel, and navigation of applications to improve their overall appearance.

UI and UX are critical to the design of an app. While UI takes care of the appearance, UX includes navigation and such. Since UI/UX plays a major role in changing the look and feels of the app entirely, these elements can help in improving the user experience. For building a successful iOS app that is also aesthetically pleasing, you must hire iOS developers who are skilled in handling the UI/UX elements.

You should hire iOS developers who have a fair idea of design concepts to create attractive designs.

Knowledge of storyboards

A storyboard is a diagram for an iOS application, showing user interface screens and the connections between them. Each scene in a storyboard is composed of a view controller and its views, connected by segue objects that represent transitions between screens.

Storyboards enable you to visualize the appearance and flow of your application's user interface. Storyboards are the recommended way to design the user interface of your application because they enable you to see a complete picture of its behavior.

Hire iOS developers with enough knowledge of Storyboard. It is after all important to make the app easier to operate.

The above-mentioned technical skills are necessary to look for when companies hire iOS developers. But, it is crucial to look beyond the technical skills and consider soft skills parallelly to hire a competent and creative iOS developer.

Non-technical skills iOS developers must have

When we think of iOS developers, only their technical expertise comes to mind. However, soft skills, as well as non-technical skills, play a significant role in making the developers highly successful.

Moreover, developers with the right attitude and professional ethics ensure timely delivery of the projects and bear responsibility for their actions. So, companies must look for the following skills while choosing to hire iOS developers.

Here are the essential non-technical skills iOS developers must possess:

Good communication skills

When working on a project, iOS developers must interact with the clients and other team members to collaboratively arrive at the desired outcome.

Good communication and conversational skills are undoubtedly vital parts of the iOS developer skillset. Make sure you hire iOS developers who can effectively communicate their ideas. This not only aids the developers in understanding the requirements of the project or client but also helps in presenting an alternative scenario with a better outcome.

Critical thinking

Every job comes with a fair share of challenges. And iOS development is no easy walk in the park.

Developers must overcome several obstacles and roadblocks to create a successful iOS app. An iOS developer must always approach a problem with rational thinking and analyze the situation to arrive at the required solution. Hire iOS developers with the right mindset who are quick on their feet as this can work wonders in times of crisis. This type of critical thinking can lead to company growth as well.


The workplace is constantly changing with the technical world bringing in new trends at every turn. So when things don’t go as planned, it is important to adapt to the change and proactively learn how to deal with it. Now, this does not mean giving in at the sight of adversity. Hire iOS developers who can adapt to the ever-changing world and learn to implement those changes in your app to make it better suited for the current situation.

Team player attitude

The development of a well-curated iOS application requires a team effort. As a result, synergy is the key to meeting client expectations and getting the desired outcome. In order to achieve these goals, one must not be just a team player, but also a strong communicator who knows how to bring out the best in others as an iOS developer.

While some people struggle with teamwork, it is crucial to maintain the dynamics of the team. So when choosing to hire iOS developers, look for developers who work well in a team as well as use their individual strengths for team growth.

Ability to Innovate

Not all clients have a clear picture of what they want as the end product. And, at times things get lost in translation as well. Or there is a high chance that the client’s requirements are impossible to achieve.

At times like these, iOS developers must innovate and develop the best application that is profitable as well as user-friendly. It is not always easy to find and hire iOS developers who are innovative but come up with an in-depth assessment that can help you sort out the best from the rest.

Work ethic

Having a strong work ethic such as being punctual, organized, meeting deadlines, staying focused, etc may seem trivial when compared to major aspects of the job. But they are important and prove that the iOS developer prioritizes work.

Whether working in a team or independently, a disciplined and focused approach will help in producing better outcomes. So, companies must hire iOS developers who exhibit a professional work ethic to ensure a cultural fit and growth.


iOS developers play an important role at every stage of iOS app development. From gathering client requirements and planning to the development of a scalable UI and integration of all pieces, iOS developers are accountable for the smooth sailing of the whole project from inception to completion.
