How to hire offshore iOS developers? Skills to look for, interview questions, and more

The demand for offshore iOS developers has gone up significantly and today an increasing number of startups and enterprises are looking for highly skilled developers. But finding top-level offshore iOS developers in such a saturated market can be tricky, as there is a limited supply of elite-level developers. However, with Turing, you can hire the best pre-vetted offshore iOS developers within 4 days.

If you want assistance hiring offshore iOS developers, we have put together an excellent resource to help you hire the best developers. This resource will help you find the right offshore iOS developers with the most relevant skills and provide you with the most essential interview questions to assess the caliber of the developers. Let’s get started!

Skills to look for when hiring offshore iOS developers

Proficient offshore iOS developers should have the following skills in their repertoire:

1. Expertise in Swift and Objective-C

Swift and Objective-C are the main programming languages used for developing iOS applications. Swift is a modern, powerful language designed for safety and high performance, while Objective-C is a more traditional language that is still used for developing or maintaining iOS apps. Deep knowledge of both languages ensures developers can work on any iOS project effectively.

2. Proficiency in iOS frameworks

UIKit and SwiftUI are essential frameworks that enable developers to create visually appealing and responsive user interfaces on iOS devices with ease. UIKit, the foundation of iOS app design before iOS 13, offers an extensive array of UI-building components like views, controls, and navigation for crafting custom interfaces.

On the other hand, SwiftUI, introduced in iOS 13, revolutionizes UI development with its declarative syntax and approach, making it easier to build consistent, adaptive, and accessible interfaces.

3. Understanding of core data

Core Data is a robust framework that manages data storage and persistence in iOS applications, allowing for efficient organization, querying, and retrieval of data. Through its powerful object graph and persistence features, Core Data facilitates developers in creating high-performing apps that maintain data consistency and integrity.

A highly-skilled offshore iOS developer should have an excellent grasp of core data and its functioning along with other essential skills to manage different project requirements.

4. Good grasp of UI/UX skills

A well-designed user interface (UI) and user experience (UX) play a critical role in an app's overall success, as they directly impact user satisfaction, engagement, retention, and conversion rates. An offshore iOS developer with a strong grasp of UI/UX design skills can create aesthetically appealing, intuitive, and accessible interfaces that cater to the specific needs and preferences of the target audience. This is why it is essential to look for offshore iOS developers who are adept at UI/UX.

5. Experience in version control systems

Git is a powerful and widely-used version control system that simplifies managing source code revisions, enabling developers to work on multiple versions and features simultaneously. Familiarity with Git streamlines teamwork by consolidating changes from different team members, addressing conflicts, and maintaining a complete history of code modifications.

Having an offshore iOS developer with excellent knowledge of version control systems will lead to a more streamlined development process.

6. Excellent communication & collaboration skills

Effective communication is the key to success in any team-oriented project, especially when working with offshore developers who may be in different time zones and have different cultural backgrounds.

An offshore iOS developer with strong communication and collaboration skills can articulate their ideas clearly, understand project requirements, identify potential challenges, and proactively seek clarification when needed.

They can efficiently communicate with both technical and non-technical team members, offering valuable insights, discussing concerns, and collectively steering the project toward success.

Create a hiring funnel

Creating a hiring funnel will provide you with numerous benefits, like assisting you in identifying the top skills and identifying an offshore iOS developer who will fit into your company's culture.

Top interview questions to hire offshore iOS developers

If you are a hiring manager looking for proficient offshore iOS developers, it is critical to evaluate their technical proficiency in iOS development. Here are some iOS interview questions to help you get started with the evaluation process.

In Swift, let and var are used to declare constants and variables, respectively. The key differences between using let and var are as follows:

  • Mutability: let is used to declare a constant, which means its value cannot be changed once it has been assigned. In contrast, var is used to declare a variable, allowing its value to be modified after the initial assignment.
  • Assignment and Initialization: Constants declared with "let" must be assigned a value at the time of declaration and cannot be left uninitialized. Variables declared with "var" can be assigned a value at the time of declaration or left uninitialized if their value will be assigned later.
  • Code Readability: By using "let" for constants, you can indicate to other developers that the value will not change. This can improve code readability and make it easier to understand the intent of the code.
  • Compiler Optimization: The use of constants declared with "let" can enable the Swift compiler to perform optimizations. Since the compiler knows that the value won't change, it can make certain assumptions and optimize the generated code accordingly.

Model-View-Controller (MVC) is a widely used design pattern in iOS development that helps to organize code promoting code reusability, maintainability, and modularity. The pattern divides the app's architecture into three interconnected components: Model, View, and Controller.

  • Model: The Model represents the app's data, business logic, and domain-specific rules. It encapsulates the core functionality and state of the application.
  • View: The View is responsible for the presentation layer and handles the app's user interface (UI). It presents the data from the Model to the user and receives user interactions.
  • Controller: The Controller acts as an intermediary between the Model and View. It receives input from the View, such as user actions, processes it, updates the Model if needed, and accordingly updates the View to reflect any changes in the data.

Grand Central Dispatch (GCD) is a low-level concurrency framework in Swift and Objective-C, developed by Apple to simplify the process of managing multiple tasks concurrently. GCD is built on top of system-level threads and provides an efficient way to handle concurrent operations in your iOS applications without needing to manage threads directly.

In iOS development, frames are a crucial property of UIView, representing the position and size of the view within its superview's coordinate system. The frame is a CGRect struct that consists of an origin (x, y) point and a CGSize (width, height), describing a view's rectangle in the coordinate system of its superview.

While the frame is often used for positioning and sizing, it is recommended to use Auto Layout and constraints to build adaptive and responsive interfaces that perform well across different screen sizes and orientations.

When two objects strongly refer to each other, they can never be deallocated. And this strong reference also enables them to keep each other alive. When objects hold strong references to each other, it means that each object has strong ownership of the other, which creates a cycle, and this cycle is referred to as a circular reference.

Protocol-oriented programming (POP) is a programming paradigm in Swift that emphasizes the use of protocols and protocol extensions to build flexible, reusable, and modular code. POP is an alternative to the traditional object-oriented programming (OOP) approach, which relies on class inheritance and subclassing.

Unlike OOP, where you define base classes with shared functionality and create subclasses that inherit those behaviors, POP promotes defining protocols to encapsulate shared functionality through methods, properties, and associated types.
