(a.) Objective C

Objective-C was the first programming language used to develop iOS-based mobile applications for Apple. This language is derived from the C language and incorporates object-oriented programming techniques. Although it is an older language, it is still in use, and many developers continue to use it for iOS app development.

(b.) Swift

Swift is a modern programming language that has gained popularity for developing iOS mobile apps. It was introduced in 2014 and has since become the preferred choice of many iOS developers worldwide.

2. Hybrid Apps


Hybrid mobile applications are apps that are developed once and can be installed and used on both iOS and Android platforms. They are also known as cross-platform mobile apps. There are several technologies available that enable developers to create hybrid applications. Let’s take a closer look at them.

i. React Native

React Native is a framework that enables developers to build hybrid apps for Android and iOS using JavaScript. Apps developed using React Native have nearly identical code for both platforms but may require minor modifications due to platform-specific limitations. This open-source framework is owned and maintained by Facebook.

ii. Flutter

Flutter is a powerful tool for developing hybrid apps that utilizes the Dart programming language. It is a Software Development Kit (SDK) developed by Google, and with Flutter and Dart, developers can create impressive and backward-compatible hybrid mobile applications.

Mobile App Development Process Flow: An Overview

Although there is no one-size-fits-all approach to mobile app development and different companies may have their unique process, we will present a comprehensive overview of the typical flow of activities in the mobile app development industry. Let’s explore the process in more detail.


1. Research & Information Gathering

The initial step in developing a mobile app is conducting comprehensive research and gathering relevant information. During this phase, brainstorming sessions are held to identify and document all ideas and concepts related to the app’s functionality, business model, budget, resource allocation, and more. It is also important to study customer behavior and market gaps while closely monitoring competitors, if any.


2. Defining End Goals and Objectives

Once all ideas and possibilities have been documented, the next step is to filter them and select the goals and objectives for the app. It is important to define the scope of the project before proceeding to determine other functionalities of the system.


During this phase, it is crucial to identify the target audience and the value that the app will add to their lives. This information can aid in allocating the budget for development and other necessary resources.


3. Wireframe & UI-Design

Following the completion of the second phase, the UI design stage can commence. The project’s assigned designers will receive a briefing and create visually appealing yet easy-to-navigate designs that will define the app’s overall appearance.


Wireframing is then performed to establish a roadmap and screen linkages within the app, as well as to test the frontend functionality. Although wireframing does not provide any functionality in the final product, it is crucial in identifying potential flaws and laying the design structure before development work begins.


4. Backend Development

The next stage is the backend development process, which can be regarded as the system’s backbone, as it houses all data that can be retrieved upon request using Application Programming Interfaces or APIs.


During the project’s development, it is possible that changes may need to be made to the wireframe design or backend files, which is perfectly acceptable. In fact, it is common practice in the industry to embrace changes rather than resisting them.


5. Integration of Frontend & Backend


After the completion of backend development, the integration of frontend and backend takes place. Any issues or errors can be addressed promptly, and if the design is sound, the likelihood of significant problems arising is reduced.


6. QA Test


Continuous testing is an ongoing process, but before completing a project, a final test is conducted to ensure it aligns with the project scope and use cases. This comprehensive test covers various parameters such as design, frontend-backend integration, functionality, loading times, memory usage, and more.


7. Beta Release


Once all aspects of the app have been completed, it is released to a limited audience for real-world testing in actual scenarios. This allows for the identification of any errors that may have gone unnoticed, which can then be addressed promptly before the final release.


8. Final Release


After conducting all the necessary checks, the app is ready to be released to the market. However, during the initial release, close monitoring is required to ensure any issues are promptly addressed. Following this, routine support and maintenance checks are conducted according to the schedule while users enjoy the app.


Required Resources:


Developing a mobile app requires a range of skills, which can vary depending on the scale of the project.
