A step-by-step guide to creating an iOS app


In 2023, the Apple App Store will contain that many apps. Without a question, that figure is astounding. The fact that developing an iOS app is no easy task, however, makes it much more astounding.

This nine-step method, along with a fantastic idea, a committed development team, and tonnes of tenacity, are necessary.

Research the market first

The most crucial—yet very frequently ignored—step in the creation of an app is market research. The problem is that many business owners and product developers believe they have developed a game-changing software idea. But it frequently ends up being the incorrect or unsuccessful one.

Consider the anonymous posting feature of the social media app Secret. Giving people a platform to freely express themselves was the goal. Only by conducting market research will you be able to confirm your app concept and steer clear of these pitfalls. There are several methods for doing this.

Just asking pertinent questions can help.

The first and second questions, “What problem is your software solving?” likewise, “Who will the app assist?” These can aid in your assessment of the viability of your app idea. There is no purpose for something if it doesn’t address anyone’s issue.

Asking your target market is the greatest approach to find the answers to these queries. Conduct a poll asking them about their problems and whether they would be interested in using your app concept to address them.

Also, you want to conduct a competitive analysis, which pushes you to consider both your direct and indirect rivals.

The objective is to assess their advantages (which you should build upon or incorporate) and disadvantages (which you should avoid). Yet performing product discovery is the easiest and possibly most efficient. To build a successful product, this meticulous approach refines an idea and prioritises important aspects.

But, it requires competence to pull off; therefore we advise enlisting the aid of a knowledgeable organization like IT Services India. The relevant questions must be asked in any market research project. Then, make sure you obtain good responses by getting them directly from end consumers.

Make a list of the software requirements.

A software requirements specification should be the first step in every project for any development team worth their salt (SRS). Without doing so is equivalent to a builder of homes without a set of blueprints. An SRS document provides all pertinent information about your app project, including its specifications, features, and limitations.

It acts as the only reliable source of information for stakeholders and the development team. It makes sure everyone is aware of and in agreement with the project’s specifics.

In the course of the development process, an SRS provides clarity to assist prevent misunderstandings. The SRS also serves as the foundation for all other project documents, including the statement of work (SOW) and outsourcing agreements. You should always work with the client to create an SRS. The following components must be present in the document at a minimum.

The goal and summary give a general overview of your app idea. If you’ve done your market research, filling out these areas shouldn’t be difficult. The functional and non-functional requirements are the next and most important section of the SRS. Functional requirements are the things that the app must be able to do. They go over the specific features that will assist in meeting user wants and achieving the goals of the app.

One illustration is the ability for ride-hailing apps to calculate the fare automatically. Finally, the SRS should go over the software’s constraints and limitations so that the developers may make up for them when developing.

Additionally, it guarantees that their labour stays within the parameters of the project. On the other hand, non-functional requirements concern how the software works. This includes measurements for load time, latency, and crash frequency. For instance, any financial app should have protection against hackers and fraudsters as a non-functional need.

Choose your technology platforms.

Once you have your SRS, it’s time to consider your technological stack, or the tools you’ll employ to complete the task. Since there is rarely a one-size-fits-all solution, choosing the technologies and third-party libraries to utilize with care is essential.

Every project has unique requirements and constraints that must be met with particular tools. Your development will take longer or cost more if you use the wrong tools, and the quality of your software will suffer. Fortunately, Apple’s native technology stack has you covered if you’re creating iOS apps.

Apple’s integrated programming environment (IDE), XCode, contains all the tools an iOS developer might possibly require. It has a robust build tool, a source code editor, and even a simulator to test your programme on simulated Apple devices.

Swift and Objective-C are other programming languages that are part of this stack. For the majority of tasks, it’s recommended to stick with the former because it can create iOS apps quickly and easily.

Most legacy apps are handled via Objective-C. iOS also works with C++. For computationally demanding apps like banking or 3D mobile games, this complicated but quick language works best.

In addition to this, you can employ excellent third-party tools in particular circumstances. For instance, the excellent networking package Alamo fire makes HTTP requests in iOS programming simpler.

For managing the databases in your project, you can alternatively utilise Realm or Core Data. The former is excellent if you have cross-platform applications because it serves as a single, system-wide data store.

Build the app’s wireframes.

A wireframe is a two-dimensional design that approximately depicts the appearance of your programme. It’s a validation tool that enables you to alliteratively improve your app design by getting user input. A wireframe is fantastic because it can be put together quickly, allowing you to iterate your design swiftly.

A wireframe’s primary design principle is simplicity. Simple shapes like squares and circles should be the only elements in a wireframe. Images are substituted with placeholders, and colour is only ever utilised where it is essential to the design. The simplest method is often to just use a pen and paper because you can draw more quickly and easily without having to learn any new tools.

But, there are more that you may use to build wireframes if you don’t mind learning new design tools, such Justin mind and Adobe XD.

Create the user interface for the app.

The appearance of an iOS app is just as crucial as its functionality, so you should give it significant thought during development. That’s because a well-designed user interface has a big impact on the user experience (UX). People appreciate using your app when it is responsive, visually beautiful, and user-friendly.

Consequently, even if it had cutting-edge features, people would happily abandon it. According to a study, excellent UI design can boost conversion rates by 200%.  Fortunately, Apple’s Human Interface Guidelines are the ideal tool for iOS developers to use when building effective UI. This is a list of recommendations and rules put forth by Apple for the design of the iOS user interface. Everything is covered, including navigation and layout as well as colour and typography.

It contributes to the same look and feel of many iOS apps. The Human Interface Guidelines can be easily followed in order to implement excellent UX in your app. Also, it increases your app’s chances of getting approved by Apple for inclusion in the App Store.

Create a plan for the app’s architecture.

The internal wiring of your app—how the various components are set up and communicate with one another—is referred to as the app architecture. An application with a well-thought-out architecture ensures stability and scalability, much like how a properly wired electronic gadget operates without any problems.

Apple advises iOS apps to adhere to the Model-View-Controller (MVC) design. The MVC paradigm divides the app’s user interface, data, and logic into components called View, Model, and Controller, respectively.

By structuring the software in this way, it becomes more modular and is thus simpler to create and maintain.

MVC, however, could be too basic and constrained for bigger, trickier programmers. Fortunately, you can take into account alternative architectures. By adding data binders to the mix, the Model-View-View Model (MVVM) architecture becomes even more modular than MVC. Here at DECODE, it is the preferred architecture.

You can also take into account the VIPER model, which has five components, if you desire even more molecularity. Back-end and front-end development should continue. It’s time to start the main event—development—now that all the preparations have been completed. The code for the app will start to be written here.

This entails front-end and back-end development for the majority of apps.

The user interface, in this case the programme itself, is referred to as the front end. It requires programmers to code the user interface, navigation, and some logic for the app.

The majority of processing, however, takes place in the back end. The database and web server code are included. The application programming interface, or API, joins the two parts. For instance, when a user conducts a search within the app, the web server receives the request and processes it.

If additional data is required, it obtains it and delivers it back to the app front-end for user display. Your project’s essential stage, front-end and back-end development, can make or kill it. Because of this, you should only leave it to a knowledgeable development company like IT Services India, which has completed many fruitful projects.

Thoroughly test the application

An excellent app is differentiated from a good one by testing. By doing that, you can make sure the programme works as it should and has the fewest issues possible. Many functional and non-functional testing techniques can be used to achieve this. In order to completely analyse your software, both types are necessary.

Let’s now quickly go over a few of the tests you’ll take.

Smoke testing is a low-level method that you’ll frequently start with to see if the app or code is ready for additional testing. It serves as a gatekeeper method before additional, stricter testing.

Performance testing is the term for a group of techniques that assess how well the app is functioning. It involves evaluating its reaction time, scalability, and load capacity. Scalability testing, load testing, and stress testing are examples of sub-tests in this case.

Usability testing, a non-functional technique that evaluates the UX of your app, is the last thing I want to mention. End customers are frequently tested to see if the app suits their needs and preferences well.

Make sure the software complies with App Store requirements. The final step is to publish your software in the Apple App Store after it has been finished. It’s not as easy as uploading your app and selecting Publish, though.

One of the most thorough evaluation procedures in the business is employed by the Apple App Store. In 2017 and 2019, they only rejected about 5 million applications, or about 33% of submissions, annually. Make sure your software complies with Apple’s App Store Review Guidelines to increase your chances of success.

It would be beneficial if you additionally searched for and discovered methods to avoid the most typical causes of rejection.


You now know the straightforward nine-step procedure for developing an iOS app. You’ll undoubtedly run into a number of difficulties, obstacles, and problems along the way in practice.
