How to Make an iOS App

Want to create the next big iPhone app and publish it on the Apple App Store? With over 1.8 million iOS apps in the App Store, the market for great apps is huge.

Whether you’re an experienced developer or a complete newbie, this guide will take you through the process of how to make an iOS app from start to finish.

The iOS App Development Landscape

Before we get into the meat of iOS app development we need to understand the landscape.

The App Store and iOS

The App Store is a crowded marketplace but it’s also a huge opportunity for developers. With millions of users across all Apple devices like the iPhone, iPad and Apple TV your iOS app can reach a massive audience.

To ensure your app stands out among nearly 2 million apps in the iOS App Store, it is crucial to have a structured marketing plan before the app’s launch and employ various strategies to enhance its discoverability.

iOS Tools and Resources

To start developing iOS apps, you’ll need to get to know the essential tools and environments required:

  • iOS SDK (Software Development Kit): This is the base of iOS development, the tools and interfaces.
  • Xcode: Apple’s integrated development environment (IDE) for building iOS apps.
  • Swift or Objective-C: The programming languages for iOS development.

Planning and Research

Planning and research are crucial stages in the development of a successful iOS app. Before diving into the development process, it’s essential to validate your idea, conduct market research, and create a solid plan for your app.

How to Make an iOS App

Step 1: App Idea

Every app starts with a great iOS app idea, and it’s crucial to validate and refine your concept before proceeding. Consider:

  • What problem will your app solve
  • Research existing apps in the same space
  • Who is your target audience
  • What will make your app unique

Validate Your Idea

Validating your idea is the first step in the planning process. This involves researching your target audience, analyzing your competition, and determining the feasibility of your app. You can use tools like SensorTower, Apptopia, and Appfigures to gather data on your competitors and identify gaps in the market.

To validate your idea, ask yourself the following questions:

  • What problem does my app solve?
  • Who is my target audience?
  • What are the key features of my app?
  • How will I monetize my app?
  • What is the unique value proposition of my app?

By answering these questions, you can determine whether your app idea is viable and worth pursuing.

Design and Prototyping

Design and prototyping are critical stages in the development of an iOS app. A well-designed app can make a significant difference in user engagement and retention.

Create a Wireframe and Mockup of Your App

Creating a wireframe and mockup of your app is an essential step in the design process. A wireframe is a low-fidelity sketch of your app’s layout and user interface, while a mockup is a high-fidelity visual representation of your app.

You can use tools like Sketch, Figma, and Justinmind to create wireframes and mockups of your app. These tools allow you to create interactive prototypes that can be tested with real users.

When creating a wireframe and mockup of your app, consider the following:

  • User flow: How will users navigate through your app?
  • User interface: What will the layout and design of your app look like?
  • Features: What features will you include in your app?
  • Branding: How will you incorporate your brand’s identity into your app?

By creating a wireframe and mockup of your app, you can test your idea with real users and gather feedback before investing in development.

Step 2: Learn the Basics

If you’re new to becoming an iOS developer, start by understanding the essentials:

  1. Downloading Xcode onto your Mac
  2. Learning Swift or Objective-C
  3. Getting to know the iOS SDK and development tools

There are many online resources, tutorials, and courses to learn iOS development from scratch.

Step 3: App Architecture

Before you write any code plan out your app’s structure:

  • Create wireframes and mockups of your UI
  • Design your data model
  • Plan the navigation flow

Step 4: Get Set Up

To develop iOS apps:

  1. Download Xcode from the Mac App Store
  2. Create an Apple ID if you don’t have one
  3. Sign up for the Apple Developer Program (required to submit to the App Store)

Step 5: Build Your App

Now let’s get started to build iOS apps using various development tools and methodologies:

  1. Open Xcode and create a new project
  2. Choose a template
  3. Start building your app’s features using Swift or Objective-C
  4. Test your app on the iOS Simulator

Advanced iOS Development Techniques

In-App Purchases

In-app purchases can be a great way to monetize your iOS app. Learn how to add them to your app’s UI.

Universal Apps

iOS Features

Use iOS features like:

  • Face ID / Touch ID for authentication
  • ARKit for AR experiences
  • HealthKit for health and fitness apps

Testing and Debugging

iOS Simulator

The iOS Simulator, included with Xcode, lets you test your app on multiple virtual iOS devices without the hardware.

TestFlight

Before you launch use TestFlight to distribute beta versions of your app to testers for feedback and bug reports.

Xcode Debugging Tools

Get to know Xcode’s debugging tools to debug your code quickly.

Submitting to the App Store

App Store Optimization (ASO)

Optimize your app’s metadata, title, description and keywords to get more visibility in the App Store.

App Landing Page

Create an app landing page to show off your app’s features and get downloads.

Required Assets

Gather all your App Store assets:

  • App icon in different sizes
  • Screenshots for different devices
  • App preview video (optional but recommended)

Prepare Your App for Launch

Preparing your app for launch involves several steps, including testing, optimization, and submission to the App Store.

To prepare your app for launch, consider the following:

  • Testing: Test your app thoroughly to ensure that it is stable and free of bugs.
  • Optimization: Optimize your app’s performance and battery life to ensure that it runs smoothly on a variety of devices.
  • Submission: Submit your app to the App Store and ensure that it meets Apple’s guidelines and review process.

By following these steps, you can ensure that your app is ready for launch and set yourself up for success in the App Store.

Submit to the App Store

App Store Review Guidelines
