How to Create an iOS App

Before you dive into app development, it is important to understand the basics of building iOS apps.

Mac System

You will need a Mac Computer running the most recent Mac OS version with an Intel processor to answer your question on how to build an ios application.

A Mac Mini can be purchased. Once you have the Mac Mini, you can attach it to your monitor screen.

The Mac Mini is equipped with a Core i5 processor of 3.0 GHz and 8 GB RAM.

The better hardware configuration will enable seamless iOS development. Now that you are familiar with the Mac system, it’s time to register for an Application Developer account.

Register to create an Application Developer Account

Apple Application Developer Account is free. After registration is successful, you will be able to download Xcode and access iOS SDK, development videos, and technical resources.

Register now at Apple’s official developer website. If you have any questions, the Apple official website has a step-by guide. If you do not have an Apple ID, create one and then add all relevant information to your personal profile.

Let’s now follow the step-by-step process to install Xcode.

Installation of Xcode

Xcode is the only tool that you will need to start developing iOS apps. Xcode is Apple’s Integrated Development Environment for iOS and Mac Apps.

To create seamless iOS programming, you’ll use Xcode’s graphical interface to build your apps. Xcode includes frameworks, compilers and tools as well as the iOS SDK. All these are required for software development, user interface design, and debugging.

After you’ve familiarized yourself with Xcode as an IDE, you can now get to know the installation process of Xcode.

Step 1: Launching the Mac App Store. If you’re using the latest Mac OS version, the Mac App Store icon can be found in your dock. If you cannot find the Mac App Store icon, upgrade your Mac OS.

Step 2: Search for “Xcode” on the Mac App Store, and click the FREE button to get it.

Step 3: Once the download is complete, the Xcode folder can be found on your launchpad.

This is it. You can now open Xcode to start building iOS apps.

Let’s now discuss how to set up an iOS environment.

Preparing Your Environment for iOS Development

We’ve already talked about setting up Xcode. Let’s now assemble everything needed to create apps for iOS.

Step 1: Once Xcode has been successfully installed and set up, it’s time to learn more about Xcode.

Step 2: Launch Xcode to create a new project

.Step 3: Get familiar with Xcode’s interface. There are five sections to the interface.

  • Toolbar
  • Editor Area
  • Utility Area
  • Navigator Area
  • Debug Area

These sections will assist you in your development phase.

Step 4: Now it’s time to begin building your application. In the next section, we provided a step-by-step.

iOS Development Tools

Apple app developers need to be aware of the free tools available for app development. We have listed the top iOS development tools below.

  • GitHub: This is code sharing and publishing site. It is a social network site for programmers.
  • Bitbucket is a platform similar to GitHub.
  • Stackoverflow: A forum for developers and coders
  • Google is a great way to get answers

Let’s now learn more about Apple’s design guidelines and development, so you don’t get into any trouble.

Understanding Apple’s Design and Development Guidelines

Apple has specific guidelines for launching new apps. Before launching an App Store app, every coder must follow certain guidelines. Before you start creating iOS apps, it is important to be familiar with Apple’s design guidelines and development guidelines.

App Store Review Guidelines Overview:

Safety is essential before any app is installed on a user’s device. Apple has a strict policy that bans apps that have offensive or disturbing content. Apple expects seamless performance from any app that you publish. Before you submit the app, it should be running perfectly.

Business: Get a clear understanding of the monetization strategies for your application. You can explain your business model in metadata or review notes if you aren’t sure.

Design: Apple users love applications with a clean and innovative design. Its all depend on how you design your apps.

Legal: Before you begin the process of app development, it is important to comply with all applicable laws.

Avoid common app rejections

Your app will be rejected if it has bugs, crashes, placeholder content or broken Links. Apple has identified some issues that can save your app from being rejected to avoid this.

Apple Design Guidelines

Apple expects consistency from their App Store. This does not necessarily mean your app must have rich design interfaces. The app must also contain the basic UI design elements.

This should be your sole goal in order to provide the best class application. We will be discussing three key points from Apple’s Human Interface Guidelines.

Clarity: Text, icons, and ornaments should be used in conjunction with the design’s functionality.

Respect: This is all about how you present the content. This is where the key lies: Keep your interface simple and prioritize the content.

Depth: To create an everlasting experience, you need to be able to distinguish visual, touch and transitions.

App Design: This guide explains all about app design.

User Interface Design: The latest iOS version allows you to use the built-in tools in Xcode to create a beautiful interface. This guide will help you.

Here is a step-by–step guide for starting your app development project.


How to Start Your App Development Project

Are you looking to learn how to create an iOS app? You will need Xcode and Mac to create Apple apps. This is the best time to create an iOS app.

  • Download Xcode

  • The first step is to download Xcode. It is available in the Mac Store. You will need patience as it is a long process (it may take 20 minutes to download, and one hour to install).
  • It is crucial to properly set up your project. Follow these steps.
    • Start Xcode
    • Click File > New > Project
    • Click on “App” and then click “Next”.
    • Name the project according to your preference.
    • Select SwiftUI or Storyboards
    • You can also choose between Objective C or Swift
    • Click on “Next”
    • Click create and choose the location where you want your file to be saved.
  • Writing the Code
  • Programming should be done in ViewController.swift. You can also check the other files. The Main.storyboard file contains UI. We will discuss it in a later section. We will move on to programming after we have finished with appDelegate.
    • Open ‘ViewController.swift’
  • ViewController.swift allows you to define the outlet for a label and assign text “Hello World”

    Go to ‘Main.storyboard’Under @implementation ViewController add @synthesize label; and in the viewDidUnload function add [self setLabel:nil];In viewDidLoad, add the following code: lblHello?.text = “Hello World”;
    We are done with the programming.Connecting the UI

    • Open “Main.storyboard”
    • Drag a label from the search results to the view as shown in the image.
    • To resize the Label, click on it and drag the corners squares.
    • Navigate to the ‘Attributes inspector.
    • It should be in the middle. Then, choose the font and size. We will recommend the system font and increase its size to 25.
    • Right-click on ViewController to connect Label to Storyboard
  • It’s time to run the app

That’s it. Once you have checked everything, click the Run button. Your app will start to speak its first words. This is “Hello World!”
