We do not need to use the option in this book. You may notice there is an option for source control. Xcode then asks you where to save the "HelloWorld" project. You do not need any tests for this simple project.Ĭlick "Next" to continue.

Include Tests: – Do not select this option.

We'll explain Core Data in later chapters. You do not need Core Data for this simple project.

Use Core Data: – Do not select this option.As this book is about Swift, we use Swift to develop the project. Language: Swift – Xcode supports both Objective-C and Swift for app development.If you want to learn SwiftUI, you can refer to our new book ( ). Interface: Storyboard - Xcode now supports two ways to build UI.Xcode automatically generates it for you. Bundle Identifier: - It's a unique identifier of your app, which is used during app submission.Fill in the organization identifier as "com.pikachi". If you have a domain, you can use your own domain name. Organization Identifier: com.appcoda – It's actually the domain name written the other way round.Product Name: HelloWorld – This is the name of your app.You can simply fill in the options as follows: This brings you to the next screen to fill in all the necessary options for your project.

We will talk about the code in the next chapter.

Just focus on the exercises, and get yourself familarized with the Xcode environment. Even though you now have some basic knowledge of Swift, I'm quite sure that you will find some of the code difficult to understand. When you're building your first app, I want you to keep one thing in mind: forget about the code and keep doing. To give you a sneak peak, figure 3-2 is your final deliverable. After going through the challenges in this chapter, you will keep improving your first app to make it more interesting. Extremely simple but it helps you kick off your iOS programming journey. When a user taps the button, the app shows a welcome message. Your first app, as displayed in figure 3-1, is very simple and just shows a "Hello World" button. I don't want to scare you away from learning programming.

Lastly, it makes you think programming is not difficult.

It also gives you a basic introduction to the Xcode environment.

Let's follow the programming tradition and create a "Hello World" app using Xcode.ĭespite its simplicity, the "Hello World" program serves a few purposes: It's a tradition in the programming world. It's a very simple program that outputs "Hello, World" on the screen of a device. Hello World is a program for the first-time programmer to create. You may have heard of the "Hello World" program if you have read any programming book before. You need to have Xcode 13 installed in order to work on all exercises in this book. If you have skipped the first two chapters, please stop here and go back to read them.
