Connecting devices with Bluetooth and Multipeer Connectivity

Mike Strand, with the help of several others, wrote a comprehensive tutorial on Multipeer Connectivity introduced in iOS 7.

The application created in the post:

– Has a view showing two colored shapes – called “bubbles”.
– When another device running the same application is in range,
a Bluetooth connection is enabled.
– When either user drags a bubble with their finger,
other connected devices show the same movement.
