Recommended Skills Tests for Assessing iOS Developers

Skills tests are a great way to evaluate iOS developers objectively. They help you assess candidates' practical abilities beyond what's listed on their resumes. Here are five key tests we recommend for screening iOS developers:

iOS Developer Test: This iOS online test evaluates a candidate's proficiency in iOS development fundamentals. It covers topics like Swift programming, UIKit, and iOS app architecture, which are core to building iOS applications.

Swift Test: Swift is the primary programming language for iOS development. A Swift skills assessment helps you gauge a candidate's ability to write clean, efficient code for iOS apps.

UI/UX Design Test: iOS developers often need to understand design principles. A UI/UX design test can help you identify candidates who can create user-friendly and visually appealing iOS interfaces.

Git Test: Version control is important for any development project. A Git skills test assesses a candidate's ability to manage code versions and collaborate effectively with other developers.

React Native Test: For companies developing cross-platform apps, knowledge of React Native can be valuable. A React Native assessment helps identify developers who can work on both iOS and Android platforms using a single codebase.

Structuring Technical Interviews for iOS Developers

After candidates pass initial iOS developer skills tests, it's crucial to conduct technical interviews to assess their practical abilities. While skills tests help filter out unqualified applicants, technical interviews are key to identifying the best fit for your iOS development role. Let's look at some sample interview questions to help you evaluate candidates effectively.

Consider asking: 1) 'Explain the difference between strong and weak references in iOS.' 2) 'How do you handle memory management in iOS?' 3) 'What's your experience with Core Data?' 4) 'Describe your approach to implementing push notifications.' 5) 'How would you optimize an iOS app's performance?' These questions help assess a candidate's understanding of iOS fundamentals, data management, user engagement features, and performance optimization techniques.

What's the difference between an iOS Developer and an iOS Architect?

It's common to confuse the roles of an iOS Developer and an iOS Architect, as both contribute to creating mobile applications. However, their responsibilities, experience levels, and focus areas differ significantly.

An iOS Developer typically has 1-5 years of experience and focuses on app development and implementation. Their skills are centered around languages like Swift and Objective-C, and they work on individual features or modules, making implementation-level decisions and ensuring code quality and feature completion.

In contrast, an iOS Architect has over 5 years of experience and is responsible for system design and architecture. They make high-level technical decisions, focus on the entire app structure and scalability, and ensure optimal system performance. Their role is more strategic and leadership-oriented, overseeing the technical direction of projects and typically working on app architecture and performance optimization.

What are the ranks of iOS Developers?

When hiring for iOS developer positions, many recruiters often confuse the different levels of experience and responsibility in the role. Understanding these ranks helps in finding the right candidate for your specific needs.

Junior iOS Developer: A junior iOS developer is typically new to the field, often with less than two years of experience. They possess basic knowledge of iOS development and primarily work under the supervision of more experienced developers.

iOS Developer: This role generally requires 2-5 years of experience. An iOS developer is expected to handle projects more independently, contributing to design and implementation with a solid understanding of the iOS ecosystem.

Senior iOS Developer: With over five years of experience, a senior iOS developer takes on more complex tasks and often leads projects. They guide junior developers and are responsible for architectural decisions and code quality.

Lead iOS Developer: In this role, the developer not only oversees the development team but also collaborates with stakeholders and ensures that the project aligns with business goals. They typically have extensive experience and are involved in strategic planning.

iOS Architect: An iOS architect is an expert in iOS development with a focus on system architecture. They are responsible for high-level design decisions and ensuring that overall system architecture is robust and scalable.

iOS Development Manager: This role combines technical skills with leadership. An iOS development manager oversees the entire development process, managing resources and timelines while ensuring the team adheres to best practices and project requirements.
