Question Why LifeGoalsClient uses async method?

[YugoMatsuda]

Thank you for sharing such a wonderful project! I would like to ask why you're using async in the LifeGoalsClient of the project. Since CRUD operations in Core Data can be executed synchronously, I felt there might be no need to use async. I'm not very familiar with Core Data myself, so if there's a reason behind this, I would greatly appreciate it if you could explain it to me 🙏
