No target specified for emulator. Deploying to iPhone-6s, 10.0 simulator
The simulator opens up, the Preflight app tries to load right after start-up but fails and I'm back on the home screen.
The following is added to the mytest.sim.console.log:
Oct 24 22:00:07 --- last message repeated 1 time ---
Oct 24 22:00:07 Ms-MacBook-Pro com.apple.CoreSimulator.SimDevice.E036ABB1-B4AE-43CA-B858-1C9D027E7989.launchd_sim (UIKitApplication:com.adobe.dps.preflight[0xc1da]): Service exited due to Trace/BPT trap: 5
Oct 24 22:00:08 Ms-MacBook-Pro assertiond: notify_suspend_pid() failed with error 7
I googled "Service exited due to Trace/BPT trap: 5" and found a post saying this might be a problem of the app itself:
Possible reason for your trap 5 error is because you have not provide TeamID for your project.
Since XCode8 and iOS10 , Apple had made some changes and now deploying on real device with Xcode8 and iOS10 is allowed only after provided team id.
Am I doing something wrong or do we really have a missing TeamID in the app com.adobe.dps.preflight?
The user has upgraded to Xcode 8. Since our methods to suppress code signing in Xcode 7 don’t work in Xcode 8, the tool is trying to sign the framework. As a result, the Team ID field is required, but the tool doesn’t currently have a way to deal with it.
One (verified) workaround is to use xcode-select  to change back to an installation of Xcode 7.x .
Another (unverified) workaround is to open <Your AEMM project>/platforms/ios/CordovaPlugins.xcodeproj in Xcode 8 and set the Team ID in the General page of the CordovaPlugins project, then try building again.
