[Xcode] Meaning of flags in Network Instruments trace

Hi all,

I've collected a trace in order to understand deeper a problem that occurs in my application.

After completing the trace I've noticed few flags above the timeline (see attachment).

Are you able to tell me the meaning of those flags? What are the events they are related to?

Thank you very much, Lorenzo

Hi Lorenzo,

you should be able to click on the flag to get more information on what kind of event the flag marks. Usually, it's about state changes like your app going the background or your app being terminated. Clicking on the flag should tell you more.

Hi Joachim,

thank you very for your answer.

This question relates to https://developer.apple.com/forums/thread/696762?page=1#698464022 since I was trying to verify the problem is related to background state.

For sure, as you described in the other thread, I could take advance of Time Profiler. It could take me some time to replicate.
