Unable to run tests via Xcode (via make test they run perfectly)

[dcacenabes]

Hi!
I have a doubt. I am trying to run the test suite from Xcode on a freshly cloned Rugby repository and I get compilation errors:
@testable import Rugby line throws error: No such module 'Rugby'

Steps to reproduce:

1. Clone the project from Github
2. Open Package.swift in Xcode (I tried both 15.3 and 15.4 with same result)
3. Use command+u key combination (or select run tests on the Xcode menu)

Expected output:
Tests build and run

Actual output:
Compilation error.

I am sure there must be some basic setup that I am missing. Would love to be able to run the tests from Xcode to easily debug new tests that I am working on. Thanks in advance!

Small update, by editing the schemes and adding the scheme for RugbyTests and FoundationTests, I am now able of running FoundationTests correctly from Xcode, but RugbyTests still fails with the same compiler error.

@dcacenabes I have also encountered this issue and have not found a good solution at the moment.
The easiest way to resolve it is to comment RugbyTests in Package.swift file and then, after closing Xcode, uncomment it and run the make test command.

As I understand it, this may be a bug, or we may need to move all the code to a basic target (non-executable) and test it there:

• Allow unit test targets to import and link executable targets swiftlang/swift-package-manager#3316
• https://forums.swift.org/t/unit-testing-executable-targets-with-swift-package-manager/44860

Thanks for sharing! I might take a look at this at some point, although it is not a big blocker and currently has a workaround. Maybe the workaround could be added to the documentation of the project under a "known issues" section so that the entry barrier for contributors is lower.

Thank you! I've added it there: https://github.com/swiftyfinch/Rugby#-contribution.
