Error typically occurs in Xcode when you try to build or run a target that is not present in the specified Xcode project (runner.xcodeproj in this case). The error message suggests that the target runnertests could not be found, but it did find a target named runner.

Error: Unable to find target named `runnertests`

If you encounter the error "Unable to find a target named `runnertests` in project `runner.xcodeproj`, did find `runner`," it indicates that the specified target is not present in the Xcode project. Here's how you can resolve it:

  1. Verify Target Existence: Open your Xcode project (`runner.xcodeproj`) and check if the target named `runnertests` exists. If it doesn't, you may need to add it or correct the target name specified in your build configuration.
# Example Xcodeproj structure
├── runner.xcodeproj
│   ├── project.pbxproj
│   ├── runner
│   └── other_files
  1. Update Build Configuration: Ensure that your build configuration specifies the correct target name. This could be in your build script, Xcode scheme, or any other configuration file where the target is referenced.
# Example build script or Xcode scheme
xcodebuild -project runner.xcodeproj -target runnertests
  1. Check Project File Integrity: Sometimes, Xcode project files may become corrupted. In such cases, you can try cleaning and rebuilding the project, or manually editing the project file to ensure the target is correctly defined.
# Clean and rebuild the project
xcodebuild clean

After making these adjustments, try building or running your project again. Ensure that the specified target (`runnertests`) is present in the Xcode project and is correctly referenced in your build configuration.

If you're experiencing persistent issues with your iOS folder in your existing Flutter project, you can try the following steps to resolve them:

  1. Delete the existing iOS folder from your project directory.
  2. Create a new Flutter project.
  3. Copy the iOS folder from the newly created Flutter project.
  4. Paste the copied iOS folder into your old project directory, replacing the deleted iOS folder.

This approach can help ensure that your iOS configuration is up-to-date and aligned with a freshly created Flutter project.

As a newcomer to Flutter, you may encounter errors like the one you described. Upon inspecting the Podfile, you'll notice the reference to a target named "RunnerTests". However, this target might not exist, leading to the error.

To address this, you can comment out the reference to "RunnerTests" within the Podfile, as shown below:

target 'Runner' do

  flutter_install_all_macos_pods File.dirname(File.realpath(__FILE__))
#   target 'RunnerTests' do
#     inherit! :search_paths
#   end

Although it's unclear why the "RunnerTests" target is referenced there, commenting it out resolves the issue.

I encountered the following issue:

"Unable to find a target named Runner Tests in project Runner.xcodeproj"

To resolve it, I had to delete the ios folder (Note: This is not recommended if you have made any changes to native iOS code). Then, I recreated the ios folder using the following command:

flutter create --platform ios .
