I have recently open sourced my OBD2 library for iOS & macOS that abstracts the transport protocol (WiFi, BTLE, CaptureFile), vehicle protocol (CAN, KWP, PWM, ...) and more into a set of reusable classes. Check out https://github.com/mickeyl/LTSupportAutomotive which might help you creating an own OBD2 application.

I would highly recommend going through the stream programming guide on the iOS developer library as this has code that does exactly what needs to be done for talking to a ELM wifi device.

It's really not much more than that, be sure you have the right IP and Port when connecting.

It depends on OBD device you are going to use. There are devices on WiFi, accesible by IP-address (using TCP or UDP protocol), by bluetooth, works like RS-232 port, and some other devices, which can directly be connected by cable.
