Swift package testing

[bddq]

Thanks for your great product.

I'm using PostHog package as a dependency of another package. The other package has basic Swift tests that are run with swift test command on CI.

With the PostHog dependency, I got an error because your package references UIKit. So I cannot test anymore my package.

Is it possible to split the PostHog package to have core classes in one target and UI classes in another?

Let me know if I can help more.

@bddq what can be done is to check if UIKit is available with compile flags and only then allow the code to be run, do you where exactly this is happening?

When I run swift test I got the following output:

I think we can use compile flags to ignore referenced files.

We're currently rewriting the iOS SDK as well and will take care of that in the next major.

Closed because of the new major version that should have addressed this use case https://github.com/PostHog/posthog-ios/pull/75
