I'm trying to run the "Time Profiler" instrument for my app from Xcode 7->Instruments against an iPhone 4 running iOS 7.1.2.

The instrument starts, and the clock starts ticking but everything else is blank. Nothing in the time track at the top, although it does scroll with the clock. Nothing in the sample list, or call tree panels below, both are completely empty. There are no errors shown in instruments, and the few messages in the console that might be related don't yeild any information from a google search.

Some other instruments do work on this device e.g. the Activity instrument, and every thing works fine on an iPad Air with iOS9,

Does this work for anyone else? Perhaps these old devices are not fully supported anymore?

(I was hoping xcode 7.1 would fix things, but that is the same. Reboots of the pc and device also dont help)

Thanks

It's a known issue that is being investigated--certain instruments are having trouble communicating with 7.x devices.

In the future, I would recommend filing a radar the next time you get unexpected behavior to ensure it is something we know about.

I've just encountered the same problem. I'm working with Xcode 7.1 and I'm trying to use the Time Profiler in Instruments with an iPhone 4, running iOS 7.1.2.

The Time Profiler and the app that i'm trying to measure works as it should be, but I can't see any logs in the detail pane while the clock is ticking. It sure looks like a communication problem between my iPhone and Instruments...

But I wonder if it's possible to downgrade my Xcode to a previous version or simply install an older version of Xcode beside the original? Would that fix the communication problem? Or is the issue already disolved in an other way?

Kind regards

Hi,

We would also like to use the Time Profiler on iOS7 devices.

Any update on this ? Is there going to be a beta of XCode soon that will address this issue ?

Have you given the Xcode 7.3 betas a try? It should be working there.
