[kaansariveli]

Xcode : 10.1
Swift : 4.2.1

Steps:
Create a dummy Single View App
build using :
xcodebuild -project BluepillCrashTest.xcodeproj -scheme BluepillCrashTest -sdk iphonesimulator -destination 'platform=iOS Simulator,id=<simulator_id>, OS=12.1' build-for-testing -enableAddressSanitizer YES
run bluepill using :
bluepill --xctestrun-path <path_to_xctestrun> -n 1 -d 'iPhone Xs' -v on

App crashes with error below:

It works well without addressSanitizer

I managed to reproduce this locally in the test suite by enabling the Address Sanitizer for the BPSampleApp and running the UI test for bp. I think the bug is that we're not honoring the DYLD_INSERT_LIBRARIES flag in the xctestrun file. I'll poke a bit more and come up with a fix. Thanks for reporting.

Any update on this? This error is causing problem in my application too. It would be great if you can fix it as early as possible.
