Unified logging updates

Unified logging updates were discussed in several sessions at WWDC 2024. Here are some key points:

1. Structured Logging with Swift:

   • Swift log supports structured logging by adding metadata to log messages, which provides additional context when troubleshooting problems. This was highlighted in the session Explore the Swift on Server ecosystem.

2. OSLog in Xcode:

   • Instead of using print statements, it is recommended to switch to OSLog, which provides a debug level for each message. This allows filtering by text or message type and includes metadata such as error info, debug timestamp, and library. This was discussed in the session Xcode essentials.

3. Debugging with OSLog:

   • OSLog allows you to jump directly to the line in your source where the log message is coming from, which is not possible with print statements. This feature was also mentioned in the session Xcode essentials.

4. CloudKit Console Logging:

   • The CloudKit Console allows for detailed exploration of logs, including customizable table views and exporting logs for historical comparison. This was covered in the session Use CloudKit Console to monitor and optimize database activity.
