9 min read

The error "Linker command failed with exit code 1" is a generic error message that can occur for various reasons during the build process in Xcode. To pinpoint the specific cause of the issue, you will need to look at the more detailed error messages in the build log.

Here are some general steps you can follow to resolve the issue:

  1. Clean the build: In Xcode, select Product > Clean Build Folder. You can also use the keyboard shortcut Shift + Command + K. Then try building the project again.
  2. Check for duplicate symbols: Look for any "duplicate symbols" error messages in the build log. If you find any, identify the duplicated symbols and resolve the conflict. This issue can arise if you have imported the same package or library multiple times or if you have different versions of the same library.
  3. Update the Podfile: If you're using CocoaPods, check your Podfile for any outdated or conflicting packages. Update the package versions if necessary and run pod install in the terminal.
  4. Update Xcode and Flutter SDK: Ensure you have the latest versions of Xcode and the Flutter SDK installed. Update them if necessary.
  5. Examine the build log: Look for more detailed error messages in the build log to help identify the specific issue. The error message might contain information about a missing library, an issue with the architecture, or other build configuration problems.
  6. Check build settings: Examine the build settings in Xcode for any misconfigurations, such as incorrect architectures, build flags, or linker flags.
