Why do i get xcodebuild fatal error module map file not found from command line

I have a project which uses SPM (and does not use cocoapods). It compiles and runs fine.

I can run SwiftLint autocorrect from the command line and that works too.

However, when I try to run jazzy on it, I am getting this error:

fatal error: module map file '/Users/Alex/Library/Developer/Xcode/DerivedData/Answers-akfeigwudbzjrkewvufnejnpluej/SourcePackages/checkouts/realm-cocoa/buil d/GeneratedModuleMaps/iphoneos/RealmCore.modulemap' not found

I went through many "fixes" for similar problems: I updated system preferences to allow terminal access to Developer Tools, etc.

The jazzy command works for my other projects, some of which use the SPM, which baffles me a bit. As a workaround, I will remove SPM and use carthage to create the Realm and RealmSwift frameworks I need.

For completists:

Does anyone recognize these symptoms?

First of all, whoever just upvoted this - thank you! (it reminded me to come back to this and resolve it)

The solution (now) is simple - use the latest version of RealmSwift

Notice the url in the "Location" column. That's all you need.

Delete whatever you are using that doesn't work.

Starting fresh, use the url:

"https://github.com/realm/realm-cocoa.git" 

and accept the defaults
