Undefined symbols when integrating a package containing FirebaseAnalytics into a Tuist project with a target containing FirebaseAnalytics

[TheInkedEngineer]

What happened?

While migrating to Tuist we faced a problem where when we add a package containing FirebaseAnalytics to our main project containing a target that depends on FirebaseAnalytics the project will not build due to Undefined Symbols

How do we reproduce it?

1. clone https://github.com/YAtechnologies/tmp-testing-ios
2. run tuist generate
3. build the project and you will get the errors

You are consuming the internal swift package as a tuist project. This is not the way to consume swift packages with Tuist.
I suggest on following this guide on how to consume external dependencies.

You can also look in the fixtures folder for examples on how to setup a project that is structured like yours.

[TheInkedEngineer]

@danibachar that was just an example, in the actual project, the package in an external dependency. that being said, I will check those links out and get back to you later today, thanks.

@danibachar
If the suggested approach is to use the Tuist's XcodeProj-based integration then it doesn't work for all external packages.. as some of them is not compatible with this method, (e.g. XMPPFramework , previously reported by someone here)
So only Xcode's default integration works for these packages.
