Xcode – How to add configurations to Xcode

For Python 3.5+ use:

import importlib.util
spec = importlib.util.spec_from_file_location("module.name", "/path/to/file.py")
foo = importlib.util.module_from_spec(spec)
spec.loader.exec_module(foo)
foo.MyClass()

For Python 3.3 and 3.4 use:

from importlib.machinery import SourceFileLoader

foo = SourceFileLoader("module.name", "/path/to/file.py").load_module()
foo.MyClass()

(Although this has been deprecated in Python 3.4.)

For Python 2 use:

import imp

foo = imp.load_source('module.name', '/path/to/file.py')
foo.MyClass()

There are equivalent convenience functions for compiled Python files and DLLs.

Is your Debug configuration's Base SDK set to a missing SDK? Xcode gets the specs for what flags the compiler supports from the configured base SDK. If it's missing, then Xcode doesn't know what compiler to show flags for.

Your Debug configuration might build correctly if you're using the Overview popup to set an override SDK. But since that's an override setting, the build setting inspector doesn't know about it. You have to set the base SDK to something valid, even if you're overriding it with the Active SDK popup.
