Connecting Arduino with Feather M0 Bluefruit LE

Hello,

I have a project that requires me to connect an iOS application with Arduino Uno, and the connection is by Bluetooth. I need to send text data from the application to Arduino, So I brought (Adafruit Feather M0 Bluefruit LE), but until now I didn't find a clear way to connect Feather m0 with Arduino, I now this chip hasmore capabilities than what I need but I have no time to change it and order a new one.

Please if you can help I would really appreciate it. Thank you
