Refactor project which uses GRDB into local packages

[yqiang]

I have a project which currently uses GRDB, and I am trying to re-organize the project by following this guide: https://developer.apple.com/documentation/xcode/organizing-your-code-with-local-packages.

My current plan is to move all the models to a separate package. The main motivation behind doing this is the hope that Xcode Previews will become faster.

Has anyone had success doing this? How would one add GRDB both as a dependency of the local package, as well as the main project?

This is what Package.swift looks like of the local package I'm trying to add:

let package = Package(
    name: "FitBeeModels",
    products: [
        // Products define the executables and libraries a package produces, making them visible to other packages.
        .library(
            name: "FitBeeModels",
            targets: ["FitBeeModels"]),
    ],
    dependencies: [
        .package(url: "https://github.com/groue/GRDB.swift.git", from: "6.27.0"),
    ],
    targets: [
        // Targets are the basic building blocks of a package, defining a module or a test suite.
        // Targets can depend on other targets in this package and products from dependencies.
        .target(
            name: "FitBeeModels",
            dependencies: ["GRDB"]
        ),
        .testTarget(
            name: "FitBeeModelsTests",
            dependencies: ["FitBeeModels"]),
    ]
)

After fighting Xcode for a while and many Clean Builds, I've got it working. Closing for now.
