'unarchiveObject(with:)' was deprecated in macOS 10.14: Use +unarchivedObjectOfClass:fromData:error: instead

The unarchiveObject(with:) method in macOS 10.14 has been deprecated. It is recommended to use the unarchivedObjectOfClass:fromData:error: method instead.

Here is an example of how to use the new method:

if let data = UserDefaults.standard.object(forKey: "myDataKey") as? Data {
    do {
        let object = try NSKeyedUnarchiver.unarchivedObject(ofClass: MyClass.self, from: data)
        // Use the unarchived object
    } catch {
        // Handle error
    }
}

This example assumes that you have stored an archived object with the key "myDataKey" in UserDefaults. The unarchivedObject(ofClass:from:error:) method will try to unarchive the object of the specified class from the given data. If successful, you can use the unarchived object. If there's an error during unarchiving, you can handle it accordingly.
