When I go to rebuild my app, the generated swift/objective C bridging header file (i.e. Module-Swift.h) for one of my modules (included as an external Xcode project with source and framework) is suddely not found by Xcode and my build fails. The only recovery seems to be a clean and rebuild (obviously not ideal).
Is this an indication I have an issue with my setup, or is this an Xcode bug?
My XCode is Version 8.3.3 (8E3004b)
UPDATE:
It seems to be happening when I edit the swift files in the module itself. It was not happening, I went to lunch, and then it started. It seemed random initially, but it appears to be when editing source of the module in question.
UPDATE 2:
It's actually 100% now. Any code change results in this issue.
FINAL UPDATE:
Seems after build finishes, the header is flagged by IDE as not found. So seems as soon as build finishes, the generated file cannot be found.
