Xcode Previews throw errors when using SPM with a multi-module setup

Question

I am using Swift Package Manager (SPM) with a multi-module setup in my Xcode project. However, when trying to use Xcode Previews, I am encountering errors.

Could anyone help me troubleshoot this issue or suggest a workaround? I would greatly appreciate any advice or insights.

I rewrote the bundle like this for Previews but it did not work.

import class Foundation.Bundle
import class Foundation.ProcessInfo

private class BundleFinder {}

extension Foundation.Bundle {
    /// Returns the resource bundle associated with the current Swift module.
    static var current: Bundle = {
        let bundleName = "StudyLegends_Generated"

        var candidates = [
            // Bundle should be present here when the package is linked into an App.
            Bundle.main.resourceURL,

            // Bundle should be present here when the package is linked into a framework.
            Bundle(for: BundleFinder.self).resourceURL,

            // For command-line tools.
            Bundle.main.bundleURL,
        ]

        // FIX FOR PREVIEWS
        if ProcessInfo.processInfo.environment["XCODE_RUNNING_FOR_PREVIEWS"] == "1" {
            candidates.append(contentsOf: [
                // Bundle should be present here when running previews from a different package
                Bundle(for: BundleFinder.self).resourceURL?.deletingLastPathComponent().deletingLastPathComponent().deletingLastPathComponent(),
                Bundle(for: BundleFinder.self).resourceURL?.deletingLastPathComponent().deletingLastPathComponent()
            ])
        }

        for candidate in candidates {
            let bundlePath = candidate?.appendingPathComponent(bundleName + ".bundle")
            if let bundle = bundlePath.flatMap(Bundle.init(url:)) {
                return bundle
            }
        }
        fatalError("unable to find bundle named \(bundleName)")
    }()
}

SPMs autogenerate a `Bundle` named `.module`. use this one for accessing any Resources in that package. why the linker fails is hard to tell without more info: - are all dependencies correctly declared in package manifest? - are you building Previews in the correct Xcode scheme? the linker error clearly states what files are missing (LoginFeature). check if it is built. — tim, Apr 23 '23 at 18:41

For some reason this is not alway needed, but also add the target as a product in the manifest so:

.library(
    name: "LoginFeature",
    targets: ["LoginFeature"]),

Then when you are in the file with the preview make sure the "LoginFeature" Scheme is selected. (it looks like a building icon, not the pink stack icon). Not sure if this is your issue or not, but worth trying.
