Levure Framework - testing app with xcode simulator

[nicoloose]

This is my first submission to the App Store. I have built my app with Trevor's Levure application framework and sqlYoga. I have installed and tested my app on my iPhone X (everything works well). I must test on simulator and take screen shots for app submission. I have installed the app on the simulator but the app does not run, no errors, nothing. Just shows the splash screen and then seems to close.

Running
MAC Mojave 10.14.1
xCode 10.1
Livecode 9.3
IOS 10 and Up for the simulator.

I have quite xCode and simulator and removed any reference in memory "sudo xcrun simctl erase all". This does not fix the issue.
I have also packaged the app with development and distribution provisioning profiles but still the same.

Is there any log I should be looking at or anything that can help me track down why the app wont run on simulator?

Not actually solved but just found a workaround and apple have accepted my screenshots.
