How to get data from an OPC server into my iPhone Xcode project? I have an OPC server and I want to communicate with it to send and receive data from it. I really have no idea where to start. Thank you!
I see that Unified Automation's C++ SDK does mention XCode support in this document
While not for Xcode, I have had success with these SDK's that use Xamarin to build apps that run on iOS and Android.
