Hi

I want to prevent files stored in my apps applicationSupportDirectory from being transferred when a user sets up a new device. Is there any guidance, an event to subscribe to that can be implemented to handle this?

Thanks

I want to prevent files stored in my apps applicationSupportDirectory
from being transferred when a user sets up a new device.

On what platform?

And what’s your reason for this? For security reasons (you don’t want the files escaping from the original device)? Or because of the storage impact? Or migration time impact?

How strict is that requirement?

If you really don’t want a file to escape this device then a good option is to encrypt the file with a random key and then store that in the keychain with kSecAttrAccessible set to one of the TheDeviceOnly values.
