Install iOS Qt5.13.0 binaries (snapshot 5.13.0-201902010707) and launch Creator 4.8.1, open any of the projects and build. Build fails with:

Error while building/deploying project addressbook (kit: Qt
5.13.0 for iOS)
The kit Qt 5.13.0 for iOS has configuration issues which might
be the root cause for this problem.
When executing step "Make"
13:29:41: Elapsed time: 00:11.
If the .xcodeproject file created (by Creator) for the project is opend in Xcode and build there, Xcode will say there is issues, dialog is opened (see attachment) and if the 'Perform Changes' is clicked xcode is able to build and launch the appliation in iOS simulator.
Apparently has something to do with the code signing
