Explanation:
When encountering the error “unable to find a target named ‘runnertests’ in project ‘runner.xcodeproj’, did find ‘runner'”, it means that there is an issue with the specified target in the given Xcode project.
In Xcode, a target refers to a specific application or framework within a project. Targets can have different configurations and build settings, allowing you to create multiple variations of your project.
In this specific case, the error message indicates that the target ‘runnertests’ could not be found in the project ‘runner.xcodeproj’, but a target named ‘runner’ was found.
To resolve this issue, you may consider the following steps:
- Verify the target name: Double-check the target name specified in your Xcode project settings. Ensure that it is spelled correctly and matches the target you want to build.
- Check the project configuration: Make sure that the specified target is included in the project configuration. Navigate to the project settings in Xcode and ensure that the ‘runnertests’ target is added and properly configured.
- Check for rename or deletion: If the error persists, verify if the ‘runnertests’ target has been renamed or deleted. This can often occur if the project has undergone changes or if the target was manually modified outside of Xcode.

You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again. Example:
git checkout -b
