PCH was compiled with module cache path error

Question

I changed the name of my username and home folder for my Mac and now when I try building a new project I get an error during the compiling process. How would I correct this?

I already cleaned the build folder

:0: error: PCH was compiled with module cache path '/Users/edgarmartinez/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/2Y7VT4EKQOHHI', but the path is currently '/Users/hannibalmartinez/Library/Developer/Xcode/DerivedData/ModuleCache.noindex/2Y7VT4EKQOHHI'

:0: error: missing required module 'SwiftShims'

Answer 1

Deleting the build folder worked for me.

This happened with me when re-created my react-native project in a different folder and then moved to a different path. This answers helped me. – Jackpot

for me the build folder was inside the project's root folder, under the name .build. in order to see it I had to run ls -ld .?* at project's root folder to search for hidden files and folders – Misconceive

Answer 2

When i move the project ABAdressbook to another directory, I got the following error:

PCH was compiled with module cache path
 '/Users/guo/Desktop/Guo/ABAdressbook/DerivedData/ModuleCache.noindex/3D6110VGP95KX'
, but the path is currently 
'/Users/guo/Documents/Projects/ABAdressbook/DerivedData/ModuleCache.noindex/3D6110VGP95KX'

Its a bit different form @Hannibal but all look like the file path is the key.

As my error point to DerivedData, so i delete this folder and rebuild it. This error disappeared.

Answer 3

I found that changing the derived folder name like alyoshak mentioned in the answer I have linked to worked. If you go Xcode Preferences->Locations then change "DerivedData" to "DerivedData2" and switch the dropdown to relative that should make a new folder and then when you hit build it should fix your issue. https://stackoverflow.com/a/34188668

Answer 7

When i change my project path, i get the same problem. I deleted the flutter_project_name/build and flutter_project_name/ios/DerivedData, then it's working for me.

If you're working in a Kotlin Multiplatform project, don't forget to delete the YourProject/shared/build folder!
