How to determine whether full disk encryption is enabled in ios

I want to know whether full disk encryption is enabled on the iPhone, and what I should do with code

Hello FancyHan

Yes, unlike macOS, all data on your iPhone is encrypted by default.

Macs with Apple silicon and Macs with Intel processors and T2 chips always use full disk encryption, irrespective of the FileVault 2 setting. Enabling FileVault 2 on a Mac with Apple silicon or with T2 changes (improves) how the keys are managed, but does not change the use of full disk encryption. Platform Security, page 92
