Unable to launch this sample project. Xcode says it cannot open the file. Building a custom peer-to-peer protocol I'm trying to build iPhone as a mouse. I am not planning on releasing it but more like a practice for myself. I have one other question, how to use a mac app to receive mouse data while it's in background as it's required by my app. Is Background Tasks the right way ? I am planning to use Network framework for networking but there is not much documentation available. Pardon me if it's a basic question.
