New Stytch Xcode project won't build `Could not find or use auto-linked library 'swiftXPC': library 'swiftXPC' not found`

A brand new SwiftUI Xcode project won't build if I add Stytch as a dependency. Error message: Could not find or use auto-linked library 'swiftXPC': library 'swiftXPC' not found

This project has literally zero changes. Only added Stytch.

Steps to reproduce:

Xcode > File > New Project > App > Storage (None), No tests > Save
File > Add Package Dependencies > https://github.com/stytchauth/stytch-ios > Add Package
Build Settings > Linking - General > Other Linker Flags > -ObjC (I did this for both the project and the target)

This happens if I add the -ObjC flag or not.

I tried several different versions of Stytch SDK, Everything since 0.18.0 doesn't work. Earlier ones do, for some reason.

I can add several other packages, like Firebase, Stripe, etc. and they work just fine. This issue only happens with the Stytch package.

stytchauth / stytch-ios
