Localizable strings in Swift Package Manager

I recently migrated my libraries into a SPM. My libraries contains also a UI stuff and pre-defines loclaized strings e.g.:

titleLabel.text = NSLoclaizedString("onboarding.page1.title", comment: "Blah blah blah")

I'm using a BartyCrouch for automating localization which ignores my libraries (expected). The real issue for me tho, is that when I put these in Localizable.strings manually, they're being ignored too

My question is: Is there any way how to localize those?

What I've tried, with no luck:

Inside my Swift Package:

public class LocalizableBridge {
    public static let shared = LocalizableBridge()
    public var bundle: Bundle = .main
}

final class MyViewController: UIViewController {

   // some code...

   private func setupLayout() {
        loadingLabel.text = NSLocalizedString("plugin.loading-state.title", tableName: "Localizable", bundle: LocalizableBridge.shared.bundle, value: "plugin.loading-state.title", comment: "LOADING")
        loadingLabel.textColor = .lightGray
        activityIndicator.startAnimating()
    }

    // some code...
}

Inside my project:

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?
    var appCoordinator: AppCoordinator?

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {

        // some code...

        LocalizableBridge.shared.bundle = Bundle(identifier: "my.projects.bundle.id")!

        // some code...

        return true
    }
}

Thanks guys in advance
