How to Develop an iOS App [A Complete Guide]

Looking to develop an iOS app?

In this guide, we will show you how to develop an iOS app and the prerequisite you need to know before developing an iOS app.

Being a leading iOS app development services providing company, we know how to develop iOS apps easily. So, here is a brief comprehensive guide for you. To write this guide, we have contacted app development consultants and the head of the iOS team who has built over 2800 iOS apps.

Let’s understand this further.

Basic Requirements to Develop iOS Apps

Before diving into iOS app development, you must understand the basic requirements and programming languages like Swift and Objective-C to build iOS apps.

1. Mac System

   To answer your question about how to build an ios app, start working with the current version of Xcode, you need a Mac Computer with an Intel processor running on the latest Mac OS version.

   You can purchase a Mac Mini. After you get the Mac Mini, attach it with your monitor screen and you are ready.

   Mac Mini comes with a 3.0 GHz Core i5 processor and 8 GB memory.

   Since the better hardware configuration will allow seamless iPhone application development. As you have understood in and out of the Mac system, it is time for registering yourself for an Application Developer account.

2. Register for an Application Developer Account

   Registering for an Apple Application Developer account is free. After successful registration, you will have permission to download Xcode, and access iOS SDK and development videos along with technical resources.

   Now is the time to register yourself at Apple’s developer website. In case of doubt, there is a step-by-step guide on Apple’s official website or iOS platform. You just require to create an Apple ID (if you don’t have one) and mention all the information in your personal profile.

   Now, let’s check to set up Xcode by following the step-by-step method.

3. Installation of Xcode

   The only tool you need initially to develop iOS apps is Xcode. Xcode is Apple’s Integrated Development Environment (IDE) for iOS and Mac Apps.

   When you will start building your apps, you will use the graphical interface of Xcode to perform seamless iOS programming. Xcode consists of frameworks, compilers, tools, and iOS SDK. You will need all these for designing a user interface, software development, and debugging purposes.

   As you have familiarized yourself with Xcode, an IDE, it is time that you get acquainted with the installation procedure of Xcode:

   Step 1: Launching of Mac App Store. You can find the Mac App Store icon in the dock if you are using the latest version of Mac OS. Upgrade your Mac OS if you are unable to find it.

   Step 2: Search “Xcode” in the Mac App Store and click on the FREE button to download it.

   Step 3: As the download will complete, the Xcode folder will be found on the launchpad.

   That is it. Now, you can easily open Xcode and start building your apps for iOS.

How to Develop an iOS App in 5 Steps

Here is a step-by-step guide to developing an iOS app

1. Setting Up Your Development Environment

   To develop an iOS app, you first need to set up your development environment. This begins with acquiring the essential tools. The primary tool for iPhone app development is Xcode, Apple’s official integrated development environment (IDE). You can download Xcode directly from the Mac App Store. Once installed, take some time to familiarize yourself with its interface, as it’s where you’ll be spending most of your development time.

   

2. Registering for an Apple Developer Account

   Next, you’ll need to register for an Apple Developer Account. This account is crucial if you wish to test your app on an actual device or eventually submit it to the App Store. While there’s a free tier available, to access all features, including app distribution, there’s an annual fee.

3. Designing Your App’s User Interface

   With your environment set up, you can start developing your app. Launch Xcode and create a new project. This will give you a basic template to start with. From here, you can start UI design of your app. Xcode provides a visual interface designer where you can drag and drop various UI elements like buttons, labels, and images. This visual representation is known as the storyboard.

4. Coding and Functionality with Swift

   However, an app isn’t just about its appearance; it’s about functionality. This is where the Swift programming language comes into play. Swift is Apple’s recommended language for iOS development. Within Xcode, you’ll find Swift files associated with different parts of your app. Here, you’ll write the code that dictates what happens when a user interacts with the elements you placed in your storyboard.

   The programming should be done in the ViewController.swift file. Moreover, you can always check other files as well. Main.storyboard file is UI, but we will talk about it in a later section. Leaving appDelegate we will jump right on to programming.

   • Open ‘ViewController.swift’
   • In ViewController.swift we define the outlet of a label and assign text “Hello World”.

   

5. Testing Your iOS App

   Xcode offers a simulator that mimics the behavior of various iOS devices. This allows you to see how your app would run on an iPhone or iPad without needing the physical device. However, it’s always a good idea to test on a real device if you can.

6. Deploying to the App Store

   Once you’re satisfied with your app’s functionality and design, and after rigorous testing, you can think about deploying it. Before submitting to the App Store, ensure your app adheres to Apple’s guidelines. Prepare your app’s listing with engaging screenshots, a compelling description, and any other required metadata. After submission, Apple will review your app, and if it meets their standards, it will be published on the App Store.

How to Shorten the Learning Curve of iOS App Development

1. Set Clear Objectives:
   Before diving into iOS development, outline your goals. Whether you’re aiming to develop a specific app, secure a job, or just acquire a new skill, having a clear objective will guide your learning journey and keep you motivated.
2. Master Swift

   Swift is Apple’s programming language for app development for iOS. Begin with the basics of Swift, understanding its syntax, and core concepts. A strong foundation in Swift will make the subsequent stages of iOS app development smoother.

3. Interactive Learning Platforms

   Platforms like Swift Playgrounds offer an interactive environment where you can write Swift code and see immediate results. Such platforms are excellent for beginners as they provide instant feedback, making the learning process engaging and effective, and makes user interaction easy.

4. Prioritize Hands-on Experience

   Theory is essential, but practical application solidifies knowledge. Start by building small, simple apps to practice what you’ve learned. Over time, challenge yourself with more complex projects. Replicating existing apps can also be a great way to understand the development process.

5. Utilize Templates

   There are numerous iOS app templates available online. These templates can give you a head start by providing a pre-defined structure for your app, allowing you to focus on customization and functionality rather than starting from scratch.

6. Online Courses and Tutorials

   Websites like Udemy, Coursera, and RayWenderlich offer structured courses tailored for different skill levels. These platforms often provide a mix of video lectures, reading materials, and hands-on projects. Additionally, Apple’s official documentation and tutorials are invaluable, offering insights directly from the source. If you want to know about the courses in detail, here is a blog on the best iOS app development courses.

7. Join Bootcamps

   Bootcamps are intensive training programs designed to take you from beginner to proficient in a short time. While they require a significant time commitment and often come with a cost, the focused curriculum and expert guidance can drastically shorten the learning curve.

8. Engage with the Developer Community

   The iOS developer community is vast and active. Engaging in forums, attending local developer meetups, or participating in online platforms like Stack Overflow can provide support, answer queries, and offer opportunities for collaboration.

9. Master Debugging Early

   Debugging is a crucial skill. Familiarizing yourself with Xcode’s debugging tools early on will help you identify and rectify errors efficiently, saving time and frustration in the long run.

10. Stay Updated

    The tech world, especially mobile app development is ever-evolving. Subscribing to iOS development blogs, podcasts, or YouTube channels ensures you’re always informed about the latest trends, tools, and best practices.
