App crashes while Recording in Instruments

I am trying to run Instruments on my app, as soon as I click record the app launches and crashes with following error:

-[__NSCFString _stringByResolvingSymlinksInPathUsingCache:]: unrecognized selector sent to instance

But when runs fine when installed and run using Xcode directly (without Instruments).

It is happening on Simulator as well as iPhone.

Xcode version: 10.2

MacOS: 10.14.4

RESOLVED: Upgraded to Xcode11 and not facing this issue anymore.

I do believe it is something related to the Certificate signing it seems that you are running on Xcode that you didn't configure the provisioning profile on

After trying many things, switching to an iOS 12.0 simulator was ultimately what got things working for me. I never figured out the root cause though, so YMMV.

I was originally using Xcode 10.2.1 and building for an iOS 12.2 simulator when I ran into this issue. I first tried cleaning the build folder, erasing the simulator, and updating to Xcode 10.3 but got the same error each time. If simply switching to a 12.0 simulator doesn't work for you, try some of those options!
