Why should you hire iOS developers for your company?

An iOS developer creates, tests, and improves applications for mobile devices running on Apple's iOS operating system that aligns with their company's or client's goals and requirements. They have a solid grasp of iOS and how it interacts with various Apple devices such as the iPhone, iPad, Apple Watch, and Apple TV, as well as the ability to tailor their apps to the needs of their company or customer.

iOS developer technical skills to look out for

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 programming language is fast and stable, allowing any iOS developer to develop responsive and feature-rich iOS applications quickly. Moreover, it is open-source and quick to learn.

It is essential to have in-depth knowledge of Swift 3.0 as this is one of the most required iOS developer skills.

Experience in Xcode IDE

Xcode IDE or Integrated Development Environment is one of the iOS developer required skill that is essential for any iOS developer when you want to hire them.

An IDE contains tools and programming essentials for automation, debugging, programming, interpretation, and compiling to simplify the process of creating software or mobile apps. The resources available in an IDE make development and deployment processes easier for newly developed and existing applications.

IDE also provides an incredible user experience and reduces development time and cost for iOS app development. Ensure to look for developers who have Xcode IDE in their iOS developer skill set.

Core Data

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

Core Data significantly decreases the amount of code an iOS developer writes to support the model layer. iOS developers can use Core Data to save application data for offline use, cache temporary data, and 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 must hire iOS developers 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. An iPhone or iPad's primary short-term memory system relies on integrated RAM to temporarily store data. 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.

Any senior iOS developer should know that the app might stop functioning once it crosses the established per-process limit and must know how to fix this by proper memory management.

Skilled in source control

Source control is a system management strategy used to track the changes made in the source code. It is an integral part of app development. This technique helps prevent conflicts between developers who work on the same application. A hands-on experience with source control helps most iOS developers collaborate and streamline the iOS 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 ecosystem to introduce concurrency and parallelism in the operating system to perform heavy computing tasks in the background without affecting the user experience.

You must hire iOS developers proficient in GCD to prevent crashes and ensure high performance.

Spatial reasoning ability

One of the primary skills for an iOS app developer is spatial reasoning ability. It 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 understand 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.

UI and UX design experience

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

UI and UX are critical to the design of an app. While UI takes care of the appearance, UX includes navigation, branding, usability, etc. You should hire iOS developers with a fair idea of design concepts to create attractive applications.

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 representing 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 your application's user interface because they will allow you to see a complete picture of its behavior.

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, also known as non-technical skills, play a significant role in making 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 when hiring 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 to the iOS developer skill set. This not only aids the developers in understanding the project or client requirements 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. You must hire developers with the right mindset who can think on their feet, as this can work wonders in times of crisis. This type of critical thinking leads to company growth as well.
