macOS swift - 将数据保存到本地存储 - 最佳实践

Question

I'm a newbie in macOS development. I have an application where I need to save a string (for example a token) to some local storage, and after closing and opening app I want to retrieve this string back.

Is it somehow possible that only my app would be able to retrieve this string?

Is it better to write it to the txt file or there are some other possibilities?

Thank you.

It depends on the security of the data.

• If security matters save the string in the keychain.
• If security does not matter save the string in UserDefaults
