Share this narrative in your portfolio; it can speak volumes about your problem-solving skills, your creativity, and your resilience.

For each project, consider including a brief overview of the development process. Discuss the challenges you faced, how you overcame them, and what you learned along the way. If, for example, you built a weather app and had difficulty integrating the API that fetches real-time weather data, explain how you solved it. Did you find a new library? Did you optimize the code? This shows your ability to troubleshoot and persist through challenges, which are valuable traits in any developer.

If possible, include metrics or user feedback to validate the success of your projects. For instance, if one of your apps has over 10,000 downloads on the App Store, or has received positive reviews, be sure to highlight these achievements. It provides tangible evidence of the impact and usability of your work.

Building a strong portfolio is a continuous process. As you grow and learn as an iOS developer, so should your portfolio. Regularly update it with new projects and experiences, ensuring it remains a true reflection of your abilities and journey in the iOS development world.

The programming languages Objective-C and Swift are used to develop programs for iOS, iPadOS, tvOS, macOS, and watchOS devices. They are the main languages for writing iOS applications. These languages are object-oriented and give an opportunity to group similar tasks in the process of writing code, which greatly accelerates and simplifies the work of developers.

Objective-C programming language

Objective-C is an older language. It was first introduced in the 1980s. Gradually it was perfected and became basic for Apple devices, therefore using Objective-C you can create applications for any technique of “Apple” corporation. The advantages of this language include a high degree of code support, a huge base of training materials and a large community, similarity with the family of languages C, and compatibility with the “younger” language Swift.

Objective-C is also known as ObjC or Obj-C. It is a compiled object-oriented programming language from Apple, which is based on the C language and Smalltalk paradigms. The Objective-C language is fully compatible with C and C code compiles. The object model is built in the Smalltalk style, which means that objects are sent messages. The Objective-C compiler is part of GCC and is available on most major platforms. The language is used primarily for the two implementations of the object-oriented OpenStep interface – MacOS X (Cocoa) and GNUstep.

It is worth mentioning that this language is also message-oriented, unlike C++, which is function-oriented. In Objective-C, method calls are not interpreted as function calls, but as sending a message (with name and arguments) to an object, just like in Smalltalk. This system provides a number of advantages – any object can send any message. Thus, instead of processing a message, an object can delegate its authority to another object to do the processing. In this way, it is easy to implement distributed objects that are in different spaces. Messages are bound to the corresponding function right at runtime.

Swift programming language

In 2014, Apple introduced a new programming language called Swift. According to the developers, this language absorbed the best from the popular Objective-C and C, and at the same time received a more powerful and convenient functionality, more modern tools.

The main advantages of this language is the high speed of development of programs, reducing the code, better readability, support for dynamic libraries, improved security. Swift and Objective-C are compatible, so they can be used even within the same project.

Developing apps for iOS is done in a fairly standard yet unique way for each case. The process involves planning, research, and a clear focus. For an app to be successful, a number of steps need to be followed correctly during its development. Typically, the entire cycle consists of 7 steps.

Stages of Development

Planning and writing the Terms of Reference. Before getting down to work, it is necessary to know for what target audience an iOS-application will be developed, what problems it is to solve, and what functions will be required for the effective functioning of the program. Besides, it is necessary to carry out a complex research of the market, to understand whether the app will be competitive and in demand. This stage also includes the preparation of a technical specification for development.

Design and development. The next step is the prototyping and interface design – UX/UI. After the prototypes are agreed upon, the designer creates a visualization of the screens which the users will see on their mobile devices.

Front-end development. The user directly interacts with the external interface of the application, so at this stage the focus is on working with the different design elements. A well-designed interface allows the application to function effectively on screens with different characteristics and sizes. This allows it to display properly on both earlier iPhone versions and newer ones.

Back-end development. The initial development step, which is responsible for the functional iOS application. The stage includes server side development, specifically: authentication, functioning of user accounts, configuring the interaction with them, integration with social networks, push notifications, and much more.

API creation. An API or application programming interface links the internal and external interfaces of a mobile application. API is one of the most important elements for creating an iOS application.

Testing. After each stage of development the application is necessarily tested to make sure the application is fully functional without errors and crashes.

Launch and maintenance. Once testing is complete, the app can be published to the App Store. Adding it to the store does not mean that the work is complete. All software requires maintenance and support, as well as improving current features and adding new capabilities.

Before we get directly to the topic of development, we should talk about what applications are and why they are created. Applications can be divided into:

Native, which focus only on one specific Android or iOS platform. Such apps are quick to install, easy to work with and fully interact with the technical capabilities of the gadget without depending on an Internet connection. Developing a native app has a higher price tag and is considered a forward-thinking strategic move.

Cross-platform apps are created for multiple platforms at once. They use the JavaScript programming language and its frameworks, on which projects for different platforms can be implemented. Cross-platform development is suitable for non-customized projects and can be just as efficient, but less costly in resources.

In addition to the technical characteristics, it is necessary to mention the type diversity. Applications can be divided into many groups, such as:

  • Entertainment (games, image processing, audio and video formats).
  • Assistants (information search, weather applications, etc.).
  • Informational (news, events, etc.)
  • Social networks
  • Leisure (sports, hobbies, travel).
  • E-commerce – mobile online stores (the ability to buy through apps).
  • B2B applications in the structure (internal control systems and organization of processes within the company).

Each group has its own peculiarities and allows the full potential of business, entertainment or public projects.
