Hi @harryapps,  
good question but how are you planning to read that? via USB, serial port, wi-fi? It will all depend on the 3rd party libraries that you will use to communicate.

cheers,

Jayant

@harryapps,  
so you are running a web server on arduino and using a webview on iOS to request, is that correct?

If that is what you are after, then you need to look into URLSession ([Apple Developer Documentation](https://developer.apple.com/documentation/foundation/urlsession?changes=_3)) to get data from an URL as you mentioned.

cheers,

Jayant
