Xcode 15 NSCocoaError 513

[Velin92]

When I try to run my tests on Xcode 15 with the PrefireTestsPlugin I get the following error:

I am using a custom prefire config file where I write the tests in an internal folder of the project tests

Xcode 15 does not give plugins permission to write to the project directory 🥲

As a quick solution, I can recommend writing in DerivedData.
To do this, remove the test_file_path parameter from the .prefier.yml file.

Now I'm trying to find another solution, but so far there are difficulties with this. To be honest, I'm not sure that it can be possible now: swiftlang/swift-package-manager#6814

I see, thanks for the suggestion, however I just tried it by removing the test_file_path and the UnitTests do not build since multiple commands seem to be produce the UnitTests product.

Do you know what might be causing this issue?

Could you try the latest release?

[Velin92]

Tried, and it now works thanks!
However having the code in the DerivedData has some downsides (sometimes the code does not preview, you cannot directly change it to play around with it, which makes editing the stencil a bit more painful, it does not render immediately until you run the tests if you use a project file builder tool like xcodegen and other small things).

Not a bid deal, but was wondering instead of generating the code through the plugin, would be possible to instead expose/use a command that we may run during the Build Phase of the app?
I guess this should allow for changes inside the project directory itself.

Btw great work, this package is amazing, will close the issue, hope this suggestion might be of help!
Thanks again.
