The initial error from Xcode was this before I changed the home folder's name:
<unknown>:0: error: invalid virtual filesystem overlay file '/Users/Mage's_Machine/Library/Developer/Xcode/DerivedData/Clima-flpmhdjedajchpfzcevzpufjznko/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/SwiftyJSON.build/unextended-module-overlay.yaml'
<unknown>:0: error: clang importer creation failed
I changed the name of the home folder of my mac after knowing through some research that Xcode does not accept nonalphanumeric characters on folder names (see: Mage's_Machine)
After doing that, I got this error:
error: PCH was compiled with module cache path '/Users/Mage's_Machine/Library/Developer/Xcode/DerivedData/ModuleCache/2RH9SWJYJWLH7', but the path is currently '/Users/Mage/Library/Developer/Xcode/DerivedData/ModuleCache/2RH9SWJYJWLH7'
Is it correct that I changed the name of the home folder? If yes, how do I compile PCH with a different module cache path to fix this error?
I'm using Cocoapods (Alamofire, SVProgressHUD, SwiftyJSON), after changing the home folder name, I got more errors. One example of these errors:
While building module 'UIKit' imported from /Users/Mage/Desktop/Clima-iOS11-master2/Pods/Target Support Files/SwiftyJSON/SwiftyJSON-prefix.pch:2:
In file included from <module-includes>:1:

I experienced this error after moving my DerivedData
location, but it equally makes sense that it would happen when changing the name of a parent folder.
Find your DerivedData
location (listed in Preferences > Locations
, as pictured below), and visit it in Finder by pressing SHIFT + ⌘ + G.
Delete the ModuleCache
folder and rebuild your target; if it still fails, you may also need to delete the ModuleCache.noindex
folder, too.
As far as I understand, this process rebuilds the module cache for all built modules. There's likely no need to clean all of DerivedData
; just these particular files.
