iOS Simulator not opening (Qt 5.13.0-beta1)

Environment:

macOS 10.14.3 

Xcode 10.1 (Build version 10B61)

Steps to reproduce:

1. Install Qt 5.13.0 beta1 iOS via online installer from staging 
2. Build any iOS example for iOS Simulator (tested with calendarwidget, wiggly)
3. Run the example

Expected result:

The example opens up in the iOS Simulator

Actual result:

The example does not open in the iOS Simulator

Application Output doesn't show any error. Just: "

09:28:15: Starting remote process.", but nothing happens despite it.

Works from Xcode.
