Step-by-Step Guide: How to Develop an iOS App

Listed below is a thorough summary of the complete app development process, from idea to App Store delivery.

1. Start With a Strong Idea

• All great apps begin with a validated strong idea. Ask yourself:
• What problem will your app solve?
• Who is your target user?
• What features will differentiate you?
• What is your budget for long-term development?

Do market and competitor research to validate your idea has true value and growth potential. 

2. Configure Your Mac System

To develop iOS applications, you are required to have a Mac computer that is using the latest version of macOS. A Mac Mini is frequently requested because it is portable and inexpensive for beginners. It supports Xcode and runs efficiently for development. 

3. Create an Apple Developer Account

To launch apps and access development resources, you have to sign up with the Apple Developer Program.
You will need:

• A valid Apple ID
• Two-factor authentication enabled
• An iPhone or iPad for verification
• Updated developer tools

Once the application is completed, you gain access to app distribution, certificates, and app testing tools.

4. Install Xcode Your Primary Development Tool

Xcode is an integrated development environment (IDE) from Apple, and has anything and everything you need to create an iOS application.

• Interface builder
• Code editor
• iOS simulator
• Debugging tools
• App Store submission support

How to install Xcode:

• First open the Mac App Store
• Search "Xcode"
• Then click install
• And last launch Xcode and set up your workspace

While there is an editor built in with Xcode, it can sometimes be easier to use separate editors like TextMate or JEdit for large code files. 

5. Use a Vector Graphics Tool for App UI Elements

To create application icons, illustrations, and any user interface elements you will need a vector tool. Some of the more popular are:

• Adobe Illustrator
• CorelDraw
• Xara Designer
• Inkscape
• DrawBerry ( beginner-friendly & free )

6. Quality visuals will give your application a professional look and feel. 

Learn Objective-C or Swif
To implement many of the features of your app, you need some programming knowledge. While many developers still use Objective-C, Apple’s current professional language is Swift. Swift is the modern, beginner-friendly programming language that you’ll enjoy coding in.

Not into coding?
You could hire iOS app developer experts who can create a professional-level app on your behalf.

7. Design the User Interface (UI)

Clean UI design is necessary for user satisfaction. Apple company focus heavily on:

• Simple design
• User clarity
• Minimalism
• Intuitive navigation
• Easy to use

To guarantee the ideal user experience, UI designers employ wireframes, mockups, prototypes, and Apple's Human Interface Guidelines.

8. Create Your App Project in Xcode

You can start your app construction with the following steps:

• Launching Xcode
• Initiating a new project
• Picking an iOS template
• Giving a name to your app
• Determining device compatibility

Then, opt for Storyboard for the layout of your app's screens. 

9. Build Screens Using Storyboards

The Storyboard is a visual representation that links all the app screens and their transitions. In this space, you are allowed to:

• Incorporate buttons, labels, input fields
• Design app workflows
• Administer ties between pages

Apply the ViewController.swift file for controlling the reasoning of every page. 

10. Set Up the Main Interface

As soon as your Storyboard is prepared:

• Navigate to the settings of your project
• Reveal the General section
• Beneath Deployment Info, pick Main.storyboard as your main interface

This way the application is aware of the place to start its routing.

11. Add Your First Screen Using a View Controller

A View Controller handles the content and organization of what’s on each screen. You can drag and drop it from the Object Library and start designing your first interface. 

12. Add Objects and Custom Elements

Add the following to every screen:

• Navigation bars
• Buttons
• Text fields
• Switches
• Labels
• Custom components

Choose the appropriate fonts, colors, and layout for an attractive and finished appearance. 

13. Add Navigation Controller

Navigation controllers provide seamless page transitions.
Navigate to:
Editor → Embed In → Navigation Controller

Your application is now prepared for multi-screen navigation. 

14. Test Your App (Crucial Step)

Testing is a process that assists in the detection and elimination of bugs, crashes, and UI errors before the submission to App Store.
Use:

• Xcode’s iOS Simulator
• Debugging tools
• Real iPhone testing

Different screen sizes should be utilized for the app running to check its compatibility.
