28 February 2025 Stephan Petzl Leave a comment Xcode

Understanding which version of Swift your Xcode project is utilizing is crucial for maintaining compatibility and harnessing the latest language features. Whether you’re developing a new project or maintaining an existing one, knowing the Swift version can help you manage dependencies and align with project requirements effectively. Here’s a comprehensive guide to determining the Swift version in your Xcode project.

Using the Terminal

The Terminal provides a straightforward method to check the Swift version installed on your machine and the one being used by Xcode:

• Open Terminal and execute the following command to see the installed Swift version:

xcrun swift -version

xcrun --find swift

Checking the Swift Version in Xcode

For a more integrated approach, Xcode’s build settings offer insights into the Swift version used by your project:

1. Open your project in Xcode.
2. Navigate to Project ► Build Settings.
3. Search for Swift Compiler – Languages.
4. Under this section, you will find Swift Language Version, which lists available Swift versions. The active version is marked with a check.

This method is particularly useful for projects with specific Swift version requirements, allowing you to quickly verify and adjust settings as needed.

Programmatic Verification

For developers who wish to programmatically verify the Swift version, the following code snippet can be utilized within your project:

#if swift(>=5.10)
print("Hello, Swift 5.10")
#elseif swift(>=5.9)
print("Hello, Swift 5.9")
// Continue for other versions...
#endif
