Xcode Instruments: Leaks - App crashes on launch

Xcode Instruments: Leaks - App crashes on launch

The app crashes on both, a device and in a Simulator.

What could cause the app to crash with the Instruments attached, while working correctly when installed using the cable or over the air via Fabric.

Update: Launching the "Allocations" instrument with the "Leaks" tab helps: enter image description here

I found my answer here, but only after discovering the "Console" view in Instruments, which included the following log message right after the app appeared to crash:

This copy of libswiftCore.dylib requires an OS version prior to 12.2.0

enter image description here

I used Xcode 10.2.1 and an iPad running iOS 12.4. So to reiterate the answer (credits to user msk):

If iOS >= 12.2, provide /usr/lib/swift as a first argument for Runpath Search Paths (under "Linking" in your Build Settings).

Actually I think this is a bug of Instruments. Try to use the Allocations template instead, then click + and add the Leaks tool.
