To make the first iOS application, double-click the XCode icon to start a new project in XCode. This will launch XCode, and we'll need to select Create a new project from the window's left pane. The window that appears after that will be opened. XCode gives us a variety of project types to pick from. Select the Single View App from the drop-down menu.

Now press the Next button. The following window will display, prompting us to fill in the project-related data. Fill in all of the product's details, such as name, team, and organisation name.

It's worth noting that the team's default selection is None. You can choose the developer name here, but you must first check-in with our Apple ID. However, I've left it blank.

You can put in the organisation's name to construct the application in the Organisation name. This proposal has been submitted to Apple Inc.

In the organisation identifier, you must fill in the identifier inverse of the organisation's domain name. For example, we'll type com.javatpoint for the company Javatpoint.

Concatenating the organisation's identity and the product name will yield the bundle identification. The bundle identifier is a one-of-a-kind identification for an application on a given platform, such as Firebase. You can't install two iOS apps with the same bundle identifier on the same iPhone.

Select the language for which you are considering development in the language drop-down menu. Swift will be our programming language in this session.

At the bottom, we're asked to select one of three possibilities. You shall not choose any of them at first. When using CoreData in iOS applications, however, the parameters are essential.

It will now ask you to choose where you want to save the work in the system. Choose where you want to save the project and then click Create. However, it will prompt us to choose a version control tool and whether or not you need to keep the Git repository on your machine. We'll leave it unchecked, and press Create. It will result in the successful creation of our first iOS application. 

Let's create our first iOS app, which will display a notification to the user on the screen. We'll start with the iOS application Hello World.
