Open Source Objective C Networking Software

BlueCove is a JSR-82 implementation on Java Standard Edition (J2SE) on BlueZ Linux, Mac OS X, WIDCOMM, BlueSoleil and Microsoft Bluetooth stack on WinXPsp2 and newer. Originally developed by Intel Research and currently maintained by volunteers.

LuLu is a free, open-source firewall for macOS developed by Objective-See. It blocks unauthorized outgoing network connections, allowing users to monitor and control which applications can transmit data externally. Designed for privacy and security, LuLu provides real-time prompts, rule-based filtering, and an intuitive interface, making it a valuable tool for Mac users seeking visibility over their system’s network behavior.

JPFPSStatus is a simple and lightweight tool that displays the frames per second (FPS) of an iOS app in real-time. Designed for performance debugging and optimization, it provides a floating overlay that shows the current FPS, helping developers monitor app responsiveness and rendering performance.

YTKNetwork is a high level request util based on AFNetworking. It's developed by the iOS Team of YuanTiKu. It provides a High Level API for network request. YTKNetwork is used in all products of YuanTiKu, including: YuanTiKu, YuanSoTi, YuanFuDao, FenBiZhiBoKe. YTKNetowrk is suitable for a slightly more complex project, not for a simple personal project. YTKNetwork is helpful if you want to cache requests, manage the dependences of requests, or validate the JSON response. And if you want to cache requests based on request version, this is one of the greatest advantages of YTKNetwork. YTKNetwork provides YTKRequest to handle every network request. You should inherit it and override some methods to define custom requests in your project. Your code is decoupled to detail network request framework, it's easy to replace it. Actually, YTKNetwork is originally based on ASIHttpRequest, we just spent two days to switch to AFNetworking.

DotNetOpenServer SDK is an open source lightweight fully extendable TCP socket client/server application framework enabling developers to create highly efficient, fast, secure and robust cloud based smart mobile device and desktop applications. Why? Unlike most application server frameworks, which are implemented over slow inefficient stateless protocols such as HTTP, REST and SOAP that use bulky ASCII data formats such as JSON and XML, DotNetOpenServer has been built from the ground up with highly efficient stateful binary protocols.

This project will work on developing ad hoc network capabilities for Apple's iPod Touch and iPhone with goals of developing a chat program.

A Cocoa utility application to display information about the clients of Apple Airport Extreme & Express Base stations

Authenticating proxy server software for Mac OS X. The front-end is written in Obj-C using the Cocoa framework, but the actual proxy daemon application is written in C using plain BSD sockets.

This project aims to discover discoverable and non-discoverable devices, connect to services device, create a fingerprint based on the BT addr, use serial port to send sms and other stuff

A Cocoa-based server for general purpose. The server manage multiple connections and connect to MySQL databases. Can be used as a start point for developers to do more complex server applications. Try it using telnet ;)

CocoaAsyncSocket provides easy-to-use and powerful asynchronous socket libraries for macOS, iOS, and tvOS. The classes are described below. The project is currently configured to build for iOS, tvOS and Mac. Simply add the package dependency to your Package.swift and depend on "CocoaAsyncSocket" in the necessary targets. You can also include it into your project by adding the source files directly, but you should probably be using a dependency manager to keep up to date. GCDAsyncSocket is a TCP/IP socket networking library built atop Grand Central Dispatch. Automatically accept incoming connections over both IPv4 and IPv6 with a single instance of this class. No more worrying about multiple sockets. Secure your socket with ease using just a single method call. Available for both client and server sockets. It runs entirely within its own GCD dispatch_queue, and is completely thread-safe. Further, the delegate methods are all invoked asynchronously onto a dispatch_queue of your choosing.

Turns EDGE data transfers over mobile carrier on and off on the iPhone (by changing the APN name and quickly rebooting)

FTPClient is a simple FREE FTP client written using Cocoa for Mac OS X.

GeoTracker is a native cocoa Mac OS X program that is able to plot the path packets travel over the internet from one host to another.

Cocoa Hesinfo GUI for MacOSX. Includes port of Hesiod 3.0.2 library as a MacOSX Framework.

isectd is a middleware daemon that provides many-to-many client-to-server connectivity. Supports multiplexing requests to multiple server processes over IP networks.

MACMonitor is a Mac OS X Cocoa application that displays AirPort connection information in convenient manners. Most useful for testing roaming Wi-Fi setups it can display both the SSID and the MAC Address and more via a menu bar extension.

Graphical User Interface for the configuration of the Mac OS X version of Synergy. Both client and server configurations are supported. You can find the current release of Synergy at http://synergy2.sourceforge.net

MacLimiter is a NetLimiter like network traffic control and monitoring tool designed for OS X.

The MacOS X Network Management Extensions (MacNME) project is an effort to extended the MacOS X Client and Server administration capabilities provided by Apple's OpenDirectory system.

A Prism/Prism2 driver for use with MacOS X and/or the Darwin operating system from Apple. This includes some UserClient interfaces to set network and encryption parameters.

A set of VNC servers and viewers which have been stripped down and run only from the commandline. The applications have a consistent, albeit minimal, UI on all platforms. Designed to be used as components in group collaboration products.

Graphical configuration editor for visual host status maps produced by Nagios (a host monitoring tool)

OHHTTPStubs is a library designed to stub your network requests very easily. It can help you test your apps with fake network data (stubbed from file) and simulate slow networks, to check your application behavior in bad network conditions, and write unit tests that use fake network data from your fixtures. OHHTTPStubs headers are fully documented using Appledoc-like / Headerdoc-like comments in the header files. Instead of writing the content of the stubs you want to use manually, you can use tools like SWHttpTrafficRecorder to record network requests into files. This way you can later use those files as stub responses. OHHTTPStubs is split into subspecs so that when using Cocoapods, you can get only what you need, no more, no less. OHHTTPStubs supports Swift 2.2 (Xcode 7), Swift 2.3 (Xcode 8), Swift 3.0 (Xcode 8+) and Swift 3.1 (Xcode 8.3+).

This project started because I wanted to learn how to use the libpcap library with Objective C. Would like to include something like this: http://drdobbs.com/showArticle.jhtml?articleID=199102239&queryText=networking+computers
