Cannot find module when Archiving in Xcode, but module is found during "Run"

Question

I installed Heap Analytics manually by copy and pasting the files over (and then added it to bridging header).

When I run on a device, everything builds fine. However, when I archive, the error is "No such module Heap".

Why is Archiving different than Running? Am I missing some configuration during the archiving process? As far as I know, nothing has been touched.

Answer 1

I work for Heap and want to pass along that the poster ultimately found that deleting the data in the DerivedData folder cleared up the error:

rm -frd ~/Library/Developer/Xcode/DerivedData/*

Answer 2

I could not compile the line: @import JavaScriptCore; and the error given was Module 'JavaScriptCore' not found. For me it was only necessary to delete the folder: ModuleCache.
The path was: ~/Library/Developer/Xcode/DerivedData/ModuleCache/

In Terminal: rm -rf ~/Library/Developer/Xcode/DerivedData/ModuleCache/*
