  1. Artificial Intelligence

Everything You Need to Know About iOS Developer

Hiring developers is not about getting new people on the team. Instead, it’s about finding the right fit.

  • Tech stack developers use
  • Roles programmers perform
  • Interpersonal skills for a smooth and timely project flow

Hire an iPhone App Developer: Technology Competencies

Let’s start with technology. Here are the competencies your candidates should have mastered:

1. Objective-C or Swift

Objective-C and Swift are two of the main programming languages needed to code an app. Swift is a newer language explicitly used for iOS devices. Nevertheless, iOS developers should know Objective-C as well.

Pros & Cons of Swift & Objective-C Programming Languages

2. Apple Human Interface Guidelines

Apple’s Human Interface Guidelines provide in-depth information on how to build user-friendly applications. To hire an iPhone developer that can create apps that match Apple’s rules and requirements, check your candidates on their knowledge of Apple’s guidelines.

3. Xcode IDE

Xcode IDE is a productive environment used for building applications for the whole ecosystem of Apple products, including iOS, macOS, Apple TV, and Apple Watch. Also, check if they are familiar with the benefits of Xcode IDE.

4. APIs

When hiring an iPhone developer, ensure that they know how to work with APIs; otherwise, you might run into problems in the middle of app development. Among the most popular iOS APIs are Google Maps, PayPal, Braintree, Facebook, MailChimp, etc.

5. Back-end support

The back-end application development for iPhone takes a lot of time and effort. You have two options: hire iOS programmers skilled in Linux, Apache, MySQL, PHP, Ruby, or Python, or use MBaaS or Mobile Backend as a Service. In any case, your candidate should be able to discuss both options.

6. UX & UI design and databases

Providing users with a seamless and intuitive interface and experience is a must. Although corresponding specialists usually handle UX/UI specifications, it’s great to have iOS developers that understand design language and can contribute to your app concept with valuable tech ideas.

7. Application security

Although iOS developers are not the architects of the app’s security, they should know the proper development guidelines and best practices to secure your code.

8. Scaling

Your app should scale seamlessly as your business grows, so it’s best to hire iOS app developers who know how to build scalable apps. An iOS developer makes many decisions that influence scalabilities like the database, architectural pattern, or cloud platform choice.

9. Code review

Quality verification is a complex process that requires knowledge of design, test cases, test plans, and more. It is recommended that you hire an iPhone developer that knows how to:

  • Run automated code reviews
  • Review code according to the standards and best practices
  • Check if the code meets non-functional requirements or NFRs
  • Find out if the code is vulnerable to security threats

This way, you can be sure that the deadlines and quality expectations are maintained as expected.
