I like constructing simple network protocols from plist/json-safe dictionaries, and transmit them over a socket as json, with as little framing as possible. Easy to prototype with, easy to debug. Give Cerfing an AsyncSocket, and it:

• Will wrap the socket to send JSON-serialized dictionaries over it
• Has a simple request-response system
• Supports Arbitrary NSData attachments
• Has an automatic 'delegate dispatching' feature, where the correct ObjC method is called based on the contents of the incoming method (very simplistic RPC)

It can also:

• Support other serializations than JSON;
• Be interleaved with another network protocol
• Wrap other socket libraries than AsyncSocket using a 'transport' abstraction.

CoreDragon is a drag'n'drop library for iOS applications. Instead of using context menus, modal view controllers, share sheets and other "indirect manipulation" ways of moving data around, it's much more intuitive to just grab the thing you want to move, and drop it on the place where you want to move it to.

CoreDragon uses similar concepts as the drag'n' drop APIs on MacOS, and modifies them to work better in a world with view controllers. It works within a single application, and on modern iPads, between applications that are running in split screen mode.

Lookback is a tool and library for user experience research that you can integrate into your app. Lookback records the iOS screen, the front-facing camera, microphone, metadata, touches and active views, and uploads it all in near-realtime to lookback.io where you can study and dive into the data. Example use cases:

• Remote research. Invite testers to test your app with just a Participate link, and no additional setp.
• User testing sessions. Instead of mounting web cams in your testing lab to record both the screen and your tester's reactions, let Lookback do the hard work for you.
• Long-term usability study. Let a user record a week of using your app, and study trends, reactions and recurring problems.

NOTE: There used to be separate "Lookback" and "LookbackSafe" pods. This pod replaces both, and is AppStore safe. Lookback HD is no more.

• Quality assurance. Record videos of found bugs, complete with a trace of how the tester reached it.

This version of Lookback is safe to use on the Apple AppStore, but this safety has heavy performance penalties. If you just want to use Lookback for video bug reports and similar internally while developing your app, consider using Lookback HD (the "Lookback" pod).

MeshPipe is an IPC (inter-process communication) library for iOS using UDP networking. It allows multiple running applications on a single iOS device to send arbitrary data to each other. It:

• Automatically connects to all other MeshPipe apps that are configured with the same port
• Detects when other apps disconnect or disappear, giving you a list of available peers

Since it is based on UDP, there are some hard-wired limitations:

• Message must fit within a single UDP datagram. The current UDP datagram max size on iOS is 9216 bytes.
• Delivery is not guaranteed. Messages may or may not get through, may arrive from seemingly unavailable peers, or arrive out of order.
• You may receive malicious or unexpected data, as any app on the phone could craft a message and send it to your app.
• Communication is insecure, and any app on the device might listen in or even change messages.
