And what prevent you to simply declare the ivar in the interface
instead of letting the compiler generating it ?
I second Andreas. For most cases, the correct place to declare instance variables should be the .m file as they are an implementation detail and not part of the contract with the outside world using the class.

As long as the ivar is declared @private, it is not part of any contract.

The symbol visibility on 64bits runtime will be set to hidden, and so the ivar cannot be referenced from an external binary (even if someone rewrite the .h file using @public instead of @private).
