macos NSUserDefaults swift

I need some guidance on I'm building a feature where I'm relatively new to this, so bear with me. I'm stuck on something that should probably be simple. I'm running into an scenario with `NSUserDefaults` where the values are not being updated as expected. I'm using macOS 13.6 and my application saves user preferences using `UserDefaults.standard`. After saving a value, I notice that when I try to read it back immediately, it often returns the old value instead of the updated one. Here’s the code snippet I’m using: ```swift let userDefaults = UserDefaults.standard userDefaults.set("New Value", forKey: "userPreference") let retrievedValue = userDefaults.string(forKey: "userPreference") print(retrievedValue ?? "No value found") ``` In many cases, `retrievedValue` prints the old value, which leads me to believe that the synchronization isn't happening instantly or there's some caching scenario. I even tried calling `synchronize()` after setting the value, but it seems deprecated and doesn't help in my case. I’ve also checked that I’m not running multiple instances of the application that might be causing conflicting writes. Is there a recommended approach to ensure that `NSUserDefaults` reflects the latest changes immediately? Any insights would be greatly appreciated! I'm working on a API that needs to handle this. What am I doing wrong? I've been using Swift for about a year now.
