问题
Whenever I run my iOS 12 app, the launch screen shows, and it closes immediately. I've tried creating a new project and run it on my device via USB, it crashes as well. However, if I run it on iOS 12 simulator, everything is working fine.
Below is the details of my build properties and environments:
OS: 10.14 macOS Mojave
Appcelerator Studio: build 5.1.1
Titanium SDK: 7.4.1.GA
iOS SDK Version: 12
Xcode: 10.0
The iPad that I am using has iOS version 12.0.1.
It's not an issue with provisioning profiles, because I've tried to generate new apps id, new profile with a new project, however it still doesn't work on the device.
Appreciate if anyone has any clue what is the cause of the crash, or any clues how to get the log file for the crash.
I tried connecting the iPad to my Mac, sync it through iTunes, and try to find the log file, but I couldn't find a way to do that either.

- Apple Worldwide Developer Relations Certification Authority
- Developer ID Certification Authority
- iPhone Developer
