Static Library error

Can you give more details about how you added CareKit? Did you add it as a SPM package or a Xcode subproject?

@fmigsystems Is this still a problem for you? We have not been able to reproduce this in Xcode 12.0 beta 4 or beta 5.

@eric-apple, I have also encountered this problem and have a use case that should be reproducible. I was working on refactoring my application to create SPM packages to collect reusable CareKit functionality. I created a Package, e.g. CareKitUtil, that imports CareKit via SPM. I then import CareKitUtil (using SPM) into my application that also imports CareKit. This scenario should produce a similar static library error as described by the original issue.

After some research, it appears that it's recommended to define Package libraries as .dynamic instead of .static

products: [

    .library(

        name: "CareKit",

type: .dynamic,

        targets: ["CareKit"]),

This change resolves my static library build error for this scenario. However, I still get a similar error if I import only CareKitStore into my CareKitUtil reusable package, instead of importing CareKit. Can/should all three of the framework packages be defined as type: .dynamic? Unsure if this will create issues for existing user configuration.

Thanks for an awesome CareKit framework!! Dave
