xpc_connection_set_peer_lightweight_code_requirement(_:_:)
Sets a requirement that the executable for the peer process has a valid code signature that matches the lightweight code requirement.
Declaration
func xpc_connection_set_peer_lightweight_code_requirement(_ connection: xpc_connection_t, _ lwcr: xpc_object_t) -> Int32Parameters
- connection:
The XPC connection.
- lwcr:
The lightweight code requirement to test for the peer process’s executable. Create an object of type Xpc_type_dictionary Swift.var that represents the requirement, using keys and values from Defining Launch Environment And Library Constraints.
Return Value
On success, 0. Otherwise, a value from Errors.
Discussion
When you set this requirement on a connection, the operating system checks that peer process satisfies the requirement every time it sends a message to your process. If the peer process initiated the connection and its executable doesn’t satisfy the lightweight code requirement, then you don’t receive a message and the operating system doesn’t call your event handler. If your process sent a message to its peer expecting a reply, and its executable doesn’t have the requested entitlement, then you don’t receive a reply and the operating system delivers XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT instead.
