App crashes while Recording in Instruments

Question

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.

Show the code only error won't help because there are lots of questions on SO related to this error — Wings, May 14 '19 at 11:26

Exactly the same. Any updates? It crashes when I run Allocations — Gabriele, Jul 30 '19 at 12:52
RESOLVED: I am now using Xcode11 and not facing this issue there. — iOS Monster, Sep 24 '19 at 09:55

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!

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
