About Swÿp

Pronounced 'Swipe.' The goal of Swyp is to allow any two apps to communicate with each other with a simple gesture bridging two touch screens.

Interoperability

The core principal of Swyp is "if you export data, you support png."

• Swyp apps will have native file formats, and usually support many formats, but they must export PNG.
• Swyp supports streaming-data pathways for music, video, or multiplayer games.
  • This is not an excuse not to support PNG export
  • Get creative! Send album art, a frame from the video, or user's game stats
  • iOS tip-- (just render a special UIView layer into an image context, then into a PNG!)
• View the protocol outline included in 'SwypProtocol.md'

Implementation

• Everything in Swyp built on bonjour, sockets and streams
  • Though this is iOS code, there's no reason it can't be brought to Android and OSX
• Swyp is peer to peer
  • Swyp supports Wifi and Bluetooth pan (in supporting devices like iOS devices) -pending @ iOS 5
  • Swyp visually presents the user with all enabled Swyp pathways (so that users know to connect to the same WiFi, for example, or turn on bluetooth)
  • Swyp could eventually be extended to support connections over cellular connections, providing a service (like Bump's) was created by some future party
• Swyp currently is as secure as the host network
  • If the feature is widely requested, we can implement a tls certificate system as an extension
  • Insecure networks will have insecure file transfer, making Swyp about average in security
