Communicate for what purpose, exactly? Just notification? Data transfer/exchange? With what level of security? Chat? Game? Video call? ...?
Hi Shri-Tam you can try Real-Time Communication with Streams
app A and app B are not from same developer.
That significantly limits your options. iOS doesn’t have a lot of IPC support to begin with, and a lot of that is restricted to apps coming from the same team.
Please explain more about the IPC you need. Are you just trying to notify of an event? Or do you need to supply a payload with that notification? Or do you need something more complex?
Share and Enjoy
