iOS 11 error message: Could not build Objective-C module 'CommonCrypto'

[alijaza]

It looks like my module.map is pointing to iOS 10.3 SDK, which is not found:

module CommonCrypto [system] {
	header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS10.3.sdk/usr/include/CommonCrypto/CommonCrypto.h"
	header "/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS10.3.sdk/usr/include/CommonCrypto/CommonRandom.h"
	export *
	}

@sgl0v first, thanks for providing this library – it's been quite handy for the past several months of use!

I integrate into my project via Cocoapods and find that when I explore the Pods/SCrypto/Frameworks/iphoneos/CommonCrypto.framework/module.map file, I too see the same as above.

I also notice the modulemap.sh and other scripts used to build this project. Initially, was there a specific reason to point at a particular SDK's crypto vs using the symlink?

In other words, would the following always be valid (example only for iPhoneOS below)?

/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonCrypto.h
/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS.sdk/usr/include/CommonCrypto/CommonRandom.h

@alijaza @skreis There is a module.map file generated by the next script. Unfortunately the module map file is not updated on pod install. Please, remove the Pods folder & run the pod install from command line.

@sgl0v thank you. I could have sworn I followed those very steps when I initially bumped into this without success.

On subsequent attempt, I followed your instructions again and it worked as expected. 👍

@sgl0v I still get the wrong version of iphonesimulator in my module.map file, even when deleting the Pods folder and re-installing (I see iPhoneSimulator11.0.sdk instead of iPhoneSimulator11.1.sdk). Can you explain where the script grabs this version number when constructing module.map?

[rredpoppy]

Same here, still the wrong version of simulator

[sgl0v]

@alijaza here is the command used to get the SDK path: xcrun --sdk iphonesimulator --show-sdk-path

I got the same issue by updating Xcode from 9.3 to 9.4 but simply deleting pods folder and running pod install worked for me :D

Deleting Pods file and re-running pod install didn't help in my case.

So Guys, i know its bit late but i got this issue and i have resolved this.
This error was coming due to the wrong path in Xcode. Recently i have downloaded Xcode and it was located in download rather than in Application. The error in Module.modulemap was showing the Path from Application/Xcode which was not available, i just moved the Xcode from Downloads to Application and ran the application and it worked!!!!. Hope this helps someone....
