What to Look for When Finding an iOS App Developer
Apple’s iOS is one of the most complex operating systems, not only in terms of usability but equally in terms of design. So, finding an expert IOS developer should be on your priority list if you’re looking to develop an iOS app for personal or business purposes.
Here are some factors to look for when finding an iOS developer.

1. In-depth Knowledge of Swift 3.0
Swift 3.0 is a powerful programming language for developing iOS apps, whether for Apple Watch, Apple TV, or Mac. Swift 3.0, an excellent programming language created to give developers total freedom and flexibility, has superb syntax and it’s easy to use. Swift 3.0 is considered an intuitive and robust language for developing different sorts of applications for Apple’s diverse platforms – MacOS, TVOS, and watchOS.
Swift is rich and reliable, thus allowing developers to develop feature-rich and vigorous mobile applications efficiently and quickly. So, when searching for an iOS developer, it’s advisable to look for one proficient with Swift 3.0 programming language.
2. XCode IDE
Another factor to consider when hiring an iOS developer is their knowledge and proficiency in XCode IDE. Versatility in XCode is one of the most important qualities to look out for when hiring a developer.
An integrated development environment (IDE) harbors the essential tools required for debugging, interpreting, and compiling codes to simplify the app development process from beginning to end.
So, a comprehensive knowledge of XCode IDE is essential for successful iOS development.
3. Core Data
Apple and iOS users are brand-centric. They trust and are fully loyal to Apple devices and iOS applications. Core Data is essentially a framework that simplifies the development of data-driven apps. Core data simplifies the management of model objects.
An in-depth knowledge of the Core Data framework relieves the developer of routine tasks associated with object lifecycle management. In addition, Core Data significantly reduces the amount of code a developer writes. iOS developers can save data for offline use, save temporary cache datasets, and undo functionality on a single device.
Comprehensive knowledge of Core Data management is a requisite when hiring an iOS developer.
4. Memory Management
Essentially, Apple’s devices are sensitive to storage. That primarily means that an iOS developer must have comprehensive knowledge of memory management. Apple devices’ short-term memories rely on integrated RAM to store and manage data.
Apple’s operating system, iOS, dynamically decides the amount of memory allocated to each application. Any superior or experienced IOS developer must know that an iOS app might stop functioning once the system reaches or exceeds the allotted storage limit. Thus, any experienced iOS developer must know how to fix memory issues when called upon to do so.
5. Unit Testing
Apple has a function that evaluates or assesses how well an app functions. Great ‘unit tests’ are fast, functional, and fully isolated. For instance, when you design a calculator app and want to test the effectiveness of a given function – division, addition, multiplication, or calculus function – you might want to create a unit test function to ensure each feature works as expected.
In addition to verifying the effectiveness of an app’s function, unit tests can help prevent bugs. The ‘unit test’ tests the functionality of a function by using inputs to ensure they generate the correct outputs.
So, it’s critical to contract or hire developers who’re well acquainted with these ‘unit test’ skills to sufficiently test an app’s overall functionality and performance.
Skills to Look Out for in an iOS App Developer
Critical skills and requirements to look out for when hiring an iOS app developer include:
- Spatial reasoning ability. Spatial reasoning ability is required when hiring an iOS developer. Ensure that your developer has the mental capacity to understand objects at varying scales and manipulate them mentally.
- UI and UX proficiency. User experience (UX) design experts specialize in the aesthetics of an app, including its overall appearance and feel. UX experts enhance an app’s overall feel, look, and navigation to improve the overall user experience. User interface (UI) experts specialize in the app’s overall usability and functionality. UI experts ensure that your app functions as expected without buffers or delays in processing inputs.
So, an in-depth knowledge of UI and UX elements is necessary when hiring an IOS developer.
