First, thanks for your time !
I'm trying to code my own app, she had to link 2 iPhone with Bluetooth. The first iPhone had to send live camera flow to the other with Bluetooth link when the app is running in sender mode. The second iPhone had to show the live, and offer the possibility to take instant photos when the app is running in receiver mode.
I don't want to install an app because I want to include other special actions in the future.
First question : May I use swift or C ?
If you need more details, don't hesitate!
