Xcode 9 “could not build module ‘Foundation’”

问题:

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?

回答1:

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

回答2:

Only reinstalling Xcode worked for me.

回答3:

This happened to me after trying to build a third party library. It made a symbolic link in the iPhoneOS.sdk/usr/include to a non-existent header file in iPhoneSimulator.sdk/usr/include.

After deleting the bad symbolic link, Xcode started building correctly again.

what you could try is :

1. Remove your pod.lock file
2. Remove your node_modules
3. yarn install in root dir
4. cd ios
5. pod install
6. clean build folder
7. build
