Build succeeds but execution fails on kill-app

[kpranavk]

I managed to finally build using Xcode 10.3 however on execution the kill-app feature, I get this error. I don't find any folders by name /usr/lib/swift. I thought Swift was installed as part of Xcode.

all I want to do is kill an app on iOS. I am using the syntax
iOSDeviceManager com.apple.Maps -d <device_id>
and it doesn't work and I get Abort trap: 6

I have seen suggestions to embed swift libraries, fix run search paths etc but none of those changes helped.

iOSDeviceManager is trying to load private libraries and failing. This is not uncommon with new versions of Xcode. We will eventually have a fix for this. You are welcome to try to fix by pulling the calabash/FBSimulatorControl fork and experimenting with the FBControlCoreFrameworkLoader loadPrivateFrameworksOrAbort method.

Hi there, any update on this? Is there an ETA on the fix?

[jmoody]

This is definitely fixed now on develop and master.
