Classification:Developer Tools Reproducible:
Xcode Project which uses a Swift Package with a Binary Dependency fails at displaying an Xcode Preview from the SwiftUI Swift View. 

Here is the error message:
Missing package product 'CairoSVG-dynamic' (in target 'SpeculidKit' from project 'SpeculidKit')


SchemeBuildError: Failed to build the scheme "Speculid"

Missing package product 'CairoSVG-dynamic' (in target 'SpeculidKit' from project 'SpeculidKit')

Build target SpeculidKit:
error: Missing package product 'CairoSVG-dynamic' (in target 'SpeculidKit' from project 'SpeculidKit')

Speculid is the macApp. SpeculidKit is the Swift package dependency. CairoSVG is a binary dependency of SpeculidKit.
