Treat Xcode warnings as errors and fail the build about apple-receipt HOT 5 OPEN

Like this:

from apple-receipt.

Which results in these types of project.pbxproj file changes:

+               GCC_TREAT_WARNINGS_AS_ERRORS = YES;
                GCC_WARN_64_TO_32_BIT_CONVERSION = YES;

                SWIFT_OPTIMIZATION_LEVEL = "-Onone";
+               SWIFT_TREAT_WARNINGS_AS_ERRORS = YES;
                TARGETED_DEVICE_FAMILY = "1,2";

from apple-receipt.

Note: Since we may do this as part of a general setting up of a new project. It may be good to know that it's better to do this when there is at least one swift file in the project. Before that Xcode does not show swift options and SWIFT_TREAT_WARNINGS_AS_ERRORS can be set only as User-Defined setting.

I also think we should make the setting project-wide (selecting a project in the list on the left instead of a particular target).

Ah! Absolutely! Good point.
