Antoine IPA: View OSLog System Logs in Real Time


If you need a reliable and user-friendly real-time viewer for OSLog System Logs that allows you to view system logs in real-time and filter them by various parameters, such as process, message, type, and more, Antoine is definitely worth considering.

What is Antoine?

Antoine, a real-time viewer for OSLog System Logs developed by Serena, which is better known for creating the Santander File Manager. OSLog provides a powerful and flexible logging system that helps developers diagnose issues and optimize performance in their iOS apps.

OSLog is a logging system introduced in iOS 10 that allows developers to collect and analyze diagnostic information about their iOS apps at runtime. It is part of the larger Unified Logging and Tracing (ULT) system provided by Apple. Antoine was released as an app for TrollStore that can be installed without jailbreaking and as a package for jailbroken devices on iOS 13 – iOS 16.

With Antoine, you can easily view System Logs in real-time and filter them by process, message, type, and more. Additionally, Antoine provides various stream options to enhance your viewing experience. Antoine works by using a private System framework, LoggingSupport.framework, a mixed C & Objective-C framework to stream system log messages.

Antoine provides a user-friendly interface for streaming logs in real-time. You can easily filter logs by various parameters, including message, process, category, subsystem, and pid. Additionally, Antoine allows you to view a range of information related to a log, such as its type and timestamp. The app can also be set to stream logs continuously in the background, although this feature requires always-on location authorization.

Once you set up the activity stream to start in the real-time viewer for OSLog System Logs, the user interface is automatically updated. You can easily pause the activity stream by calling 'os_activity_stream_cancel' on the activity stream whenever needed.

By accessing the app preferences page, you can modify the refresh rate of streaming logs from the default 1 second to as long as 10 seconds. You can also enable logging in the background mode, but it's important to note that this feature requires location services to be enabled. Additionally, you can change colors for different log types, such as info, debug, fault, and error.

OSLog provides a centralized and structured way to log events, errors, and performance metrics in an iOS app. It uses a hierarchical structure to organize logs, where logs are grouped into categories, and categories are further organized into subsystems.

In addition to organizing logs, OSLog also provides various features to help developers analyze and diagnose issues in their app. For example, it allows developers to filter logs based on specific subsystems or categories, or to search for logs that contain certain keywords.

Antoine was released as an open-source project on the GitHub repository, with source code written in multiple programming languages such as Swift (92%), C++, and Objective-C.
