What Does an iOS Developer Do?
In simple teams, an iOS developer is a developer who designs, builds, and tests applications for iOS-based devices such as iPhones and iPads. Some of their key responsibilities are as follows:
- Prototype, code, and optimize applications to be used in the iOS ecosystem
- Implement applications updates
- Remove any coding bugs
- Collaborate with designers and other developers throughout the application development process
Typically, they are a part of the product or engineering teams within an organization and generally report to a senior iOS developer or a senior software developer.
An iOS developer has a solid understanding of iOS and how the operating system interacts with different Apple devices. They also are an expert at tailoring their apps to the needs of the customers or the company.
Why is the Demand for iOS Developer Skills Increasing?
Today, there are more than one billion Apple devices in the market running on the iOS operating system. After Android, it is the most widely used mobile operating system. As a result, in recent years, the demand for skilled iOS developers has skyrocketed.
According to Apple, there are 1.8 million mobile applications. These applications are created by iOS developers with a strong knowledge of the Apple ecosystem and its operating system.
The company is paying more attention to developing high-quality, robust, and reliable applications that provide a seamless experience to the users.
Now, let’s look at the key technical iOS developer skills that you must possess to excel in this role.

Top Technical iOS Developer Skills in 2024
Technical iOS developer skills are essential because Apple follows strict quality standards for a mobile application to be listed on its app store.
The following are some of the main iOS developer skills that can help you create an efficient and reliable mobile application for the app store:
- Swift
- Xcode IDE
- Core Data
- Memory Management
- Spatial Reasoning
Let’s understand these iOS developer skills in detail.
1. The Core of iOS Developer Skills: Swift
Swift is the primary language used in iOS app development. This programming language is popular because of its efficiency, safety, and modern syntax. In the hands of a skilled iOS developer, this language becomes immensely powerful.
iOS developer skills in Swift allow the developers to write clean and readable code with very high-performance potential. An iOS developer is expected to know Swift’s features like optionals, closures, generics, etc. which are crucial for writing robust mobile applications.
Mastering Swift as an iOS developer skill will help you keep current with the latest updates and features introduced by Apple.
2. The Powerhouse of iOS Developer Skills: Xcode IDE
iOS developer skills in Xcode integrated development environment (IDE) are essential for developing mobile apps for Apple devices. It is a must-have iOS developer skill that employers look for when hiring iOS developers.
Xcode is a platform where developers can write, test, and debug their code. This makes it a key tool in the iOS development process.
iOS developer skills in Xcode include knowledge of its different features like the Interface Builder which allows developers to visually design the app’s user interface. This way the developers can create functional and aesthetically pleasing apps for iOS-based devices.
This IDE also offers several powerful debugging tools, making the iOS developer skills in this area essential for quickly identifying and resolving issues.
iOS developer skills in Xcode involve using the simulator to test the applications on different Apple devices and different versions of the operating system to ensure compatibility and optimum performance.
Mastering Xcode is considered a fundamental iOS developer skill that helps developers streamline their workflow and write high-quality mobile applications.
3. A Vital iOS Developer Skill for Data Management: Core Data
It is another very important iOS developer skill that helps in the development of data-driven applications. It simplifies the management of model objects and their relationships. With this iOS developer skill, the developer feels at ease with routine tasks associated with the object life cycle and graph management.
The Core Data provides a solution for handling large amounts of data within the app. This enables the developers to store, retrieve, and manage data efficiently.
In addition to basic data storage, iOS developer skills in Core Data include optimizing performance by focusing on efficient memory management and handling large datasets.
Mastering the Core Data iOS developer skill helps developers build scalable applications that are capable of accurately and efficiently handling large data sets.
4. A Critical iOS Developer Skill for Performance Optimization: Memory Management
iOS developer skills in memory management are the key to building functional and efficient mobile applications. It ensures that the app uses the device’s resources efficiently, avoiding memory leaks, and minimizing the app’s footprint.
iOS developer skills in this area help developers prevent application crashes and slowdowns, which otherwise can hamper the user’s experience and lead to negative reviews on the app store. In this regard, an understanding of automatic reference counting (ARC) is key iOS developer skill that helps in effective memory management.
5. An Essential iOS Developer Skill for UI/UX Design: Spatial Reasoning
iOS developer skills are essential for designing intuitive and engaging user interfaces. It involves the ability to visualize and manipulate objects in a 3D space.
This iOS developer skill allows the developers to anticipate user’s reactions and how they interact with the application. With this iOS developer skill and knowledge, the developers can optimize the app’s performance and ensure its navigation is smooth and intuitive.
This iOS developer skill is considered essential for building apps that stand out in the crowded marketplace.
