We normally override the entrypoint to _qt_main_wrapper via the -e flag
to the linker, but if a Swift file is added to the Xcode project, Xcode
does some magic, building the app as a shared library, and wrapping it
with the Swift code into a custom executable. The -e flag will then be
a noop when linking our shared library.
To work around this we set the custom LD_ENTRY_POINT Xcode build setting,
which triggers Xcode to pass -e when linking the wrapper-executable.
This works in practice, but produces a warning on the console that the
entrypoint is not found, which has been reported as FB16519113.
