What Is an iOS Developer?
An iOS developer thoroughly understands iOS, which includes how the ecosystem works across different Apple products such as iPads, iPhones, Apple Watches, and Apple TVs.
They must learn how to create and customize iOS apps.
Learn how to become an iOS Developer
If you search around, you'll find an iOS skill matrix like this one. The iOS skills matrix below is a collection of skills one needs to have to become a senior iOS Developer.
This matrix gives you a good idea about the iOS developer abilities you should have. Still, it is vague enough not to canonize any particular area. It is meant to supplement your path-finding process.
This article will cover the fundamental iOS skills you need to learn to be an iOS developer, get hired or create your own iOS app development services.
Step 1: Learn Swift
Programming is a vital skill for iOS developers. The skills you need to become an iOS app developer can be very different depending on what you know or the ones that are most effective for you to acquire.
You can use Java to build iPhone Application Development and develop Android, Mac OS, Linux and Windows apps.
You can prepare for the Java certification exam if you have a limited budget or time and anticipate you will eventually move from iOS to another platform or ecosystem. If you are passionate about software development, have time and money, and still expect to explore other ecosystems, then back-end or front-end developer training could be the better choice.
For example, you could learn how to create an iOS app that uses Angular, a MEAN stack component.
Using the languages designed for iOS or the Apple ecosystem is best. Swift is the best programming language for those just learning how to code or wanting to concentrate on iOS development.
It is best to start with Swift basics and then move on to advanced concepts before moving to iOS. This approach was developed because most iOS developers try to learn Swift and iOS simultaneously but need clarification.
The best way to proceed is to study the following.
- The basics. Include variables, numbers and strings.
- Collections. Include dictionaries, arrays and other data.
- Control flow statements. Include for/while, if-else and switches.
- Interfaces and types. Included are structures, enumerations and functions.
- Learn the basics of object-oriented programming. Include inheritance, polymorphism, and classes.
Step 2: The iOS Platform
The next step after learning Swift is to explore the iOS platform, which comprises many different frameworks and technologies, as well as design patterns.
You must know how the iOS ecosystem works even if you use a foreign programming language other than Swift.
It is important to learn the basics before you can master anything. You will need the ability to utilize more advanced technologies, such as augmented reality or artificial intelligence.
You can only build popular apps or find employment if you know the basics.
Some of the basic concepts that you need to know about the iOS platform are:
- Overview of Apple Developer (formerly the Apple Developer Connection or ADC). Apple Developer is a collection of resources you'll need to create software for iOS and macOS.
- Learn Xcode, Interface Builder and more in-depth. Xcode, or the integrated development environment (IDE), is what you will need to create software for iOS. You will require macOS to run Xcode. Interface Builder allows you to design iOS interfaces with a GUI.
- Auto Layout. Learn to use Auto Layout in Xcode.
- Table views. The table view is another important component that helps you navigate long scrolling lists within iOS apps.
- Storyboards and containers. Storyboards and containers are both useful for creating navigation flows in iOS apps.
Refrain from being concerned if these tools and concepts sound foreign to you. You can start with a basic understanding of tools and models.
SwiftUI has recently replaced the UIKit framework, which Apple introduced in 2019 at its Worldwide Developers Conference.
Step 3: Learn the Essential iOS Developer Skills
It's time to broaden your horizons. After learning how to code and using the right environment to create your iOS app, you can now expand your knowledge in other fields that will help you polish your apps.
You can grow in your skills by understanding these topics.
You can explore many different areas. You can get an overview of what you should know by looking at the iOS skill matrix.
Understanding the following knowledge areas will also greatly impact your iOS journey.
Databases
- Most modern apps, including iOS applications, rely heavily on databases to store and retrieve data. Knowing how databases function (and query languages used to manipulate the data) is a valuable skill that can help you advance in iOS development.
Networking
- Modern iOS apps often require data to be sent back and forth over the internetInternet. An iOS developer needs to understand the internetInternet. iOS simplifies the process by offering SDKs with several APIs to perform network requests. You will need to know the DNS, URLs and general networking concepts in addition to these SDKs.
iOS Developer Skills
Many other skills, besides Swift and Objective-C, are required for iOS developers.
Engineer's Perspective
Expert says, "Knowing the best way to tackle and approach a problem that you do not know how to fix has been a valuable skill I have had to use constantly at work." Meta's size and reach may have unique problems you have never encountered.
Knowing how to break these down into smaller parts and solve them is essential to make an impact at the company.

Skills that are not Technical
iOS developers should be able to work in a group. Other developers and employees from different departments, like marketing, can be included in the team.
It's essential that iOS developers at any level:
- Patient
- You can also use flexible payment methods
- Organized
- Self-driven
- Communication skills
- Ability to perform well under pressure
Techniques
You can develop the following technical skills as an iOS entry-level or mid-level developer.
- Xcode is Apple's integrated development environment. The IDE helps developers write code and build apps for different operating systems and devices. Xcode helps developers design, develop, test and debug apps before they submit them to Apple's App Store.
- Apple has guidelines for design and human interface. Apple has specific requirements for apps that appear in the App Store.
You'll have to become familiar with the following once you reach the position of Senior iOS Developer:
- Software Architecture
- Concurrency
- Reactive programming
- Animations for deployment
- Tests of User Experience
iOS Programming Languages
As an iOS Engineer, I had to know Xcode and Swift, Objective-C, and many of Apple's iOS proprietary frameworks and tooling.
Swift was designed by Apple in 2014 as the most popular programming language available for developers.
Swift also includes the following features:
- This is one of the most efficient programming languages for creating iOS apps.
- Swift apps can run on iOS devices as old as iOS 7.
- Swift and Objective-C are compatible. Objective-C is the most common language used to create iOS apps.
Objective-C, like Swift, is a general-purpose programming language. Objective-C introduced in 1984, based on the C programming language, was Apple's primary language before Swift was created.
It still represents a large portion of Apple code. Upwork's rating of Objective-C, based on its versatility and popularity among freelancer developers, reflects this.

What are the other requirements for becoming an iOS Developer?
To prepare for an iOS developer position, iOS programmers should also learn Swift and Objective C.
- Spatial Reasoning: Successful iOS developers need to be able to think in 3D and see the spatial relationships between objects. This means knowing the controls and inputs available on the various platforms and the users.
- Design Guidelines: iOS applications must adhere to strict guidelines and be user-friendly. Developers must learn how to create Model-View-Controller (MVC), delegate patterns, and notifications.
- Networking: Most apps interact with the internetInternet in one way or another. iOS developers need to know how to send data over the network using JavaScript Object Notation (JSON).
- Core Data: This framework is used to store data on Apple products. It's an important component of any app.
- Grand Central Dispatch: This allows app developers to implement concurrency, allowing them to perform multiple tasks simultaneously without affecting performance.
- Git & GitHub: The Git & GitHub platforms help version control of longer projects and team projects.
The development of iOS apps will continue to be a hot topic in 2023. New OS functionality will allow for new creative levels.
Apple also updates features for developers. In addition, technology trends such as 5G, VR, and AR also provide additional opportunities. We will explore these trends and their implications for developers in the following sections.
High-Level Technology Trends
Let's first talk about the development landscape. All app developers should be aware of the following technologies.
- 5G- Mobile connectivity's fifth generation (5G), which offers faster data transfers and lower latency, is the standard for mobile technology. Apple and all other mobile brands will adopt 5G technology by 2023. The adoption of 5G enables higher-quality apps and more features.
- AI & ML- Machine learning and AI (or artificial intelligence) are related technologies that enable prediction, personalization and other things. These technologies allow app developers to develop new apps faster and easier and boost performance.
- Beacons- Small wireless devices can gather important data at retail locations, allowing connected apps to provide useful information to consumers who choose to receive it, such as coupons.
- IoT- The Internet of Things allows ordinary objects like smart thermometers to transmit information to custom mobile application development. This gives users more control over their environment.
- Mobile Commerce- Many people prefer to shop through apps on their mobile devices rather than via websites. This phenomenon is known as "m-commerce". App developers will have new ways to enhance the shopping and boost revenue.
- AR and VR- AR and VR allow users of apps to be immersed in different experiences. These new technologies offer new possibilities for apps in all categories, such as gaming, retail, and travel.
- Wearables- Apps can be used to perform various tasks on watches, rings and clothing. Technology advances quickly in many industries, including finance for quick payments and health care for monitoring the physical condition.
New Tools for Team Development
App developers should look for these features to maximize the technology listed.
- Xcode 14- Xcode 14, new improvements to improve productivity. This application is compatible with multiple devices and includes an App icon feature. It also has language and editing enhancements.
- Xcode Cloud- This cloud-based continuous integration service is built into Xcode. It allows Apple developers to create apps automatically in the cloud. They can then test and deploy them more quickly.
- Metal 3 has new gaming features- Metal 3 represents the latest version of Apple's graphics framework. Metal 3's characteristics improve performance. These include MetalFX upscaling and a fast resource-loading API.
- SwiftUI and enhancements to Swift- New features that streamline development. These include package plugins for custom commands and layouts that create different app layout versions. This video will explain the importance of Swift.
- The WeatherKit- With this feature, developers can integrate weather forecasts into their apps. The API is accessible through native Swift APIs and REST-based APIs. It also includes calls to APIs with Apple Developer Program membership.
- SKAdNetwork Api- The API contains features that help advertisers measure app performance while protecting user privacy. Developers can also get more conversion information for smaller campaigns.
- APIs- Developers can now access new APIs, including live text on the lock screen, collaborative tools, mapKit, focus filter, automatic shortcuts, and watchOS 9.
What Are Some Of The Most Promising Opportunities For New Ios Developers?
We believe the most exciting iOS project iOS developers could find at this time would be one that allows them to try out new Apple approaches, like Swift UI."
Experts suggest that iOS developers learn about AR development, particularly with the reports of Apple releasing an AR headset in 2019.
"It's also very interesting to work in the AR field because Apple puts more and more effort into its AR technologies. Working with AR Developers can be part of developing promising technology."
Experts says that joining an organization with many applications in active development and a strong team of developers can accelerate your career.
You will only have an opportunity to develop and grow as a developer if you work for a company that is just maintaining its existing applications. Working closely with strong developers can accelerate the learning process for any developer.

What are the skills that you believe new developers need to focus on?
Experts advise junior developers to focus on mastering their trade. Take a critical look at your architecture or code.
Is there a simpler way to complete a particular task? Does the code read easily and without any comments? Is your code able to handle large volumes of data or transactions? "These questions will help you to think about more than just doing the code work.
Know your basics. To achieve the overall team goal, you must produce good code, know how to comment, and have "soft skills" (i.e.
your ability to interact with others).
Developers need to focus on improving their critical and abstract thinking. They should learn how to read other people's code, use documentation, and create small prototypes to grasp a complicated technological issue.
The developers should develop 'engineering pragmatics', which will allow them to choose a useful design approach for users and businesses. Soft skills include the ability to communicate clearly and without hesitation, as well as being able to accept help when needed.
How would a 30-day, 60-day or 90-day period look for an iOS developer starting a job?
Experts said that new iOS developers are initially overwhelmed with information. They will also be learning the theory of iOS development and how it is applied in practice.
After a few weeks, the new iOS developers will be able to breathe and relax. After that, there will still be much work to do in other iOS areas, followed by an overload. "This is the best way for any developer to grow."
Many newbie iOS programmers must be flexible due to the speed and pressures of many software development companies.
Buchniev says, "I do not think that the first days of iOS development are any different than what engineers at other companies have to deal with." "During this time, developers have to balance two important and balancing tasks. First, developers need to get to know each other, build contacts, find themselves on a new team and understand the processes.
The second is to understand the product, including its features, technical style, and pull requests.
Experts said the first 30 days are usually spent getting to know your role. Start by understanding the domain and the architecture of your application.
Also, get familiar with all tools and applications used in the company. You will also start to build relationships with the other developers.
The next month or so is usually spent going beyond the simple software changes to feature development." This involves digging deeper into code and the system's architecture to better understand it.
At this point, a deeper look into the domain is also recommended. This will inform the developer how the code and architecture match the discipline.
What is the day-to-day work of a junior iOS Developer?
Experts explain that junior developers tend to be assigned bug tickets and simple application features. Most of the time spent on a project is on understanding the structure and workings of the app, followed by debugging and stepping the code to find or address edge cases.
The tasks should be brief, and there will always be new challenges.
What Are The Skills That You Believe New Developers Need To Focus On?
We believe the most important skill for a brand new iOS developer would be building a UI using standard UIKit components." Experts say it is important to listen to and accept mentors' suggestions and be willing to take on board their amendments.
Junior programmers should learn their craft very well. Be critical of your architecture or code. Is there a simpler way to complete a particular task? Does the code read easily and without any comments? Is your code able to handle large volumes of data or transactions? "These questions will help you to think about more than just doing the code work.
It is important to use critical thinking, particularly when studying documentation and concepts written by other people.
You should learn how to read other people's code, use documentation and create small prototypes in order to grasp a complicated technological concept. Newer iOS developers must adopt an "engineering pragmatic" mindset. This will allow them to choose a design approach that will benefit users and businesses.
What is the minimum time a junior programmer should work before they seek promotion to a senior position?
Experts said that promotions shouldn't be based on time, even though some employers may view junior-level roles this way.
Promotions should acknowledge that someone has performed at a level higher than their current role. It could mean performing at an exceptionally high level, including writing excellent code quickly or going above and beyond the expected duties.
If a junior programmer is making well-informed comments about the regulation of other members, this would be considered high-level performance.
We believe that reviews help to determine when it is time for a promotion: "Performance Reviews will help us understand if a novice is ready." Start with two annual reviews, then reduce the number to just one.
"The outcome of the evaluation should be based on how well you performed during your work period."
Experts say it is not time-sensitive, but you must give yourself six months of rest before worrying about the future.
It depends on the engineers' knowledge, motivation and entry-level skills. Developers can only expect to be promoted a half-year after working in their new position. It depends entirely on how much responsibility they can handle and their ability to do so.
Promotion is about the complex maturity of the specialist, not just the knowledge of a specific technology.
