No such module 'UIKit'

8 min read

The error message "No such module 'UIKit'" usually occurs when you are trying to import the UIKit framework in a non-iOS project or when there is an issue with your Xcode project settings.

To resolve this error, follow these steps:

  1. Make sure you are working on an iOS project, as the UIKit framework is specific to iOS development. If you are working on a macOS project or a command-line tool, you should import the appropriate framework for that platform (e.g., AppKit for macOS).

  2. Check your Xcode project settings to ensure that the UIKit framework is included correctly. Here's how to do it:

    • Open your Xcode project.
    • Click on your project/target in the Project Navigator.
    • Go to the "Build Phases" tab.
    • Under "Link Binary With Libraries", ensure that UIKit.framework is listed. If not, click the "+" button and search for "UIKit" to add it.

  3. Clean and build your project. Sometimes, Xcode may have cached build results, leading to this error. Cleaning the project helps in such cases. You can do this by going to Product -> Clean Build Folder and then building the project again by going to Product -> Build.

If you have followed these steps and you still encounter the error, it could be due to a Xcode configuration issue or an issue with your installation. In such cases, try restarting Xcode or reinstalling Xcode to ensure that it is set up correctly for iOS development.
