Just use iOS build-in Data Protection and the encryption and decryption will be done by iOS automatically on writing the file and reading the file.

Set completeFileProtection when writing the data:

static var completeFileProtection: NSData.WritingOptions { get }

The file is stored in an encrypted format and may be read from or written to only while the device is unlocked. At all other times, attempts to read and write the file result in failure.

See iOS Security Page 11: Encryption and Data Protection, File Data Protection.
