Open Source Objective C Logging Software

NSLogger is a high performance logging utility which displays traces emitted by client applications running on macOS, iOS and Android. It replaces traditional console logging traces (NSLog(), Java Log). The NSLogger Viewer runs on macOS and replaces Xcode, Android Studio or Eclipse consoles. It provides powerful additions like display filtering, defining log domain and level, image and binary logging, message coloring, traces buffering, timing information, link with source code, etc. Accept connections from local network clients (using Bonjour) or remote clients connecting directly over the internet. Online (application running and connected to NSLogger) and offline (saved logs) log viewing. Buffer all traces in memory or in a file, send them over to viewer when a connection is acquired. Define a log domain (app, view, model, controller, network…) and an importance level (error, warning, debug, noise…).

LogNotifier is a Cocoa/PyObjC application that uses Growl to notify changes to log files (and shows the user the added lines). Later a PyGTK/PyQT frontend.

USRBAC is a kernel patch and userspace daemon that allows role based access control to be mitegated in userspace. The goal is to allow a secure way to impliment RBAC compliant security systems using a daemon in userspace

Log4Cocoa is an Objective-C based port of the popular Java based logging package Log4J. Additionally, Log4Cocoa plans to provide pure C based bindings as well. Log4Cocoa is not affiliated with the Apache Jakarta project in any way.
