Describe the bug
When I compile the example project with Xcode 10, I get this error.
This is a known issue documented in Swift 4.2 Release Notes for Xcode 10
Compilation might fail without displaying the errors responsible for the failure. For example, you might see the message “Command CompileSwiftSources failed with a nonzero exit code” without an accompanying failure reason. (43033749)
Workaround: Disable batch mode by adding a user-defined build setting named SWIFT_ENABLE_BATCH_MODE and set it to NO.

Once you have added the build setting, the real problem will be revealed, PryntTrimmerView.h is missing.

To fix it, run carthage update, clean the build folder and then rebuild the example project.
Umbrella header 'PrynTrimmerView.h' not found. after carthage update.
How to fix?
thanks ! solved my problem
Yup, fixed it for me, now I can see the actual compilation error.
THANKS!
In my case I connect an actual iphone not simulator and run the app once on it, It solved the problem. But connect iphone firstly, then choose it from the menu of simulator, then press run button.
The problem will solve too.
