Swift 5.2 has partial implementation of this proposal where SwiftPM is able to skip dependencies that are not exported via any product.

@neonichu @aciidb0mb3r Any updates on this when to release this support? We are getting a bunch of test target dependencies and they are conflicting with the host app.

The 5.2 partial implementation should take care of test target dependencies, but only for transitive dependencies, not for root packages.

@neonichu Thanks for the feedback, i'm not sure if i understood correctly, our Swift version for the packages is 5.7 but when we integrated SDK which depends on testing framework(Quick, Nimble) and the same testing frameworks are linked to main app using SPM, so the conflicts still happens, do you mean this issue is addressed as well in Swift 5.2?

Do you have an example you could share? AFAIK, this scenario should work, the test-only dependencies of a dependency should not matter at all.

@neonichu I have attached sample code, when you try to build the app you get following error

Failed to resolve dependencies Dependencies could not be resolved because 'mylibrary' depends on 'quick' 5.0.0..<6.0.0 and root depends on 'quick' 7.3.0.

The issue here is that "MyLibrary" is actually not a dependency but another root package in which case all of its dependencies need to be resolved.

You could fix this by instead adding "MyLibrary" as a local dependency:

• Remove the existing reference to it from the Xcode project
• Use File => Add Package Dependencies => Add Local... to add it as a local dependency instead (I believe this may need Xcode 15 or at least 14.3)

After doing this, your package will show up as a local dependency instead and the Quick/Nimble dependencies won't matter anymore. The drawback is that you cannot run tests of dependencies, though.

@neonichu Cool, looks like it's working. But the option you mentioned Use File => Add Package Dependencies => Add Local is only available from Xcode 15, but with older version of xcode still it has conflicts issue
