To measure pre-main time, you would typically use tools like Xcode Instruments, specifically the Time Profiler, to analyze the startup performance of your app. Pre-main time refers to the time taken from when the app is launched until the main function is called. This includes the time spent in dynamic library loading, static initializers, and other system-level initializations.
Unfortunately, the provided context from the WWDC sessions does not directly address measuring pre-main time. However, if you are interested in performance metrics related to media playback, you might find the session Discover media performance metrics in AVFoundation useful, as it discusses insights into AVFoundation playback sessions and related performance metrics.
