Warning with Xcode 16

Hello,

We're seeing a warning (that could become an error) when we use the Swift implementation in Xcode 16:
```
JuiceboxSdkFfi.JuiceboxRecoverError:5:16: warning: stored property 'guesses_remaining' of 'Sendable'-conforming struct 'JuiceboxRecoverError' has non-sendable type 'UnsafePointer<UInt16>?'; this is an error in the Swift 6 language mode
```

Is it something on your radar?

Thanks!
