Ionic-cli: The executable was signed with invalid entitlements.

[EnguGH]

Description:
On a brand new generated ionic app, I can't deploy it on a real iOS device : the build passes, but in the end I get a pop-up saying

The executable was signed with invalid entitlements.

Steps to Reproduce:
Launch :

ionic start myApp tabs
cordova build ios --buildFlag='-UseModernBuildSystem=0'

Then try to launch it on an iOS device

Output:

The executable was signed with invalid entitlements.

The entitlements specified in your application’s Code Signing Entitlements file are invalid, not permitted, or do not match those specified in your provisioning profile. (0xE8008016).

This is linked to XCode 10 not being supported.
It can be solved by choosing "Legacy build system" in XCode project's settings, see here: https://github.com/apache/cordova-ios/issues/407
