How do I record and inspect signposts in Instruments in Swift/Xcode?

Recording and inspecting signposts in Instruments allows developers to monitor performance and debug issues in their Swift applications. By using the signpost feature, you can gain insights into specific code executions and their timing, which can be crucial for optimizing your app's performance.

Learn how to effectively use signposts in Instruments to track execution time and inspect performance bottlenecks in your Swift applications.

Here is an example of how to use signposts in your Swift code:

import os let signpostID = OSSignpostID(log: .default) let signpostLog = OSSignpostID(tracing: .default) // Start a signpost os_signpost(.begin, log: .default, name: "Processing Data", signpostID: signpostID) // Your code that you want to measure performance for processData() // End the signpost os_signpost(.end, log: .default, name: "Processing Data", signpostID: signpostID)
