iOS localization value on swizzleMainBundle() doesn't work

[ghost]

I have the package set up, I can see the LingoHub SDK downloads the file but when I try to use it in the app there is no value.

NSLocalizedString("correct_key", comment: "") the output is the key, not value
LingoHubSDK.shared.localizedString(forKey: "correct_key") the output is the key, not the value

In the didFinishLaunchingWithOptions I call:

LingoHubSDK.shared.configure(withApiKey: apiKey, projectId: projectId)
LingoHubSDK.shared.isPreproductionEnabled = true
LingoHubSDK.shared.swizzleMainBundle()

LingoHubSDK.shared.update { result in
            switch result {
            case .success(let value):
                print("LingoHubSDK update: \(value)")
            case .failure(let error):
                print("LingoHubSDK error: \(error.localizedDescription)")
            }
        }

and in the ViewController I've tried both methods as shown above.
The LingoHubSDK.shared.update comes as true when I generate a new version of the package.

I've created a new project just to test the SDK and followed the steps in here:
