Can't compile because "Nimble/Nimble-Swift.h" can't be found

[inket]

I'm using CocoaPods to include Quick & Nimble, but it seems that Nimble can't compile anymore.

This is the error I'm having with xcodebuild. (same with Xcode)

I'm getting this too with Nimble 4.0.0 installed via CocoaPods. I was able to temporarily work around it by editing the generated umbrella header and commenting out CurrentTestCaseTracker:

#import <UIKit/UIKit.h>

//#import "CurrentTestCaseTracker.h"
#import "DSL.h"
#import "NMBExceptionCapture.h"
#import "NMBStringify.h"
#import "Nimble.h"

FOUNDATION_EXPORT double NimbleVersionNumber;
FOUNDATION_EXPORT const unsigned char NimbleVersionString[];

After this, I get warnings
/Users/david/src/EasyShiftIOS/Carbon/Example/<module-includes>:1:1: Umbrella header for module 'Nimble' does not include header 'CurrentTestCaseTracker.h'
but my tests are successfully run.

Looking for a more permanent solution as this clearly won't work for automated builds.

Hey, I was having the same issue and I've opened a pull request on Nimble to fix it: #283

In the meantime, you can use my fix immediately by using this in your podfile:

pod 'Nimble', :git => 'https://github.com/ashfurrow/Nimble.git', :branch => 'podspec-update'
