SwiftUI - Environment



SwiftUI is an interface toolkit introduced by Apple in 2019. It provides a modern way to develop user interfaces for various Apple platforms like iOS, macOS, watchOS, tvOS, etc. It supports declarative syntax, which means the developer can describe the user interface and its behaviors with the help of simple and concise Swift code.

To create a SwiftUI-base app we need to install Xcode in our system because SwiftUI is tightly integrated into Xcode, or we can say that Xcode is a primary environment for developing SwiftUI-based apps.

What is Xcode?

Xcode is an integrated development environment (IDE) which is developed by Apple to create Apps for all Apple's platforms such as iOS, iPadOS, tvOS, watchOS, macOS, and visionOS. It is free to use and provides all the tools to develop Apps. It supports various languages like Swift, Objective-C, Objective-C++, C++, Java, Python, etc. It is the only tool which is used for creating and publishing Apps on Apple's app store. It also supports cross-platform.

Xcode was first introduced by Apple in October 2003. The current version of Xcode is Xcode 15. It is very popular among Swift developers due to its features like, user-friendly interface, open source, provide good support for code completion, high-end application testing, provide simulator for all Apple devices so that developers can check how their app will look like on the actual platform, etc.
