Xcode 9 "could not build module ‘Foundation’"

Question

When I archive an iPhone project, it returns a failure:

Could not build module "Foundation".

However, when I debug on the iPhone, it runs successfully.

I tried to set ‘Enable Modules’ to No and it seems normal, but another 3rd party library I'm using requires modules be turned on.

What do I do in that case? How do I import social now?

Answer 1

Set to YES target's Allow Non-modular Includes in Framework Modules in Build Settings.
