Example-Swift.h not found

Question

I'm developing an iOS framework that mixes Objective C and Swift code. Build fails at the #import "Example-Swift.h" line with 'Example-Swift.h' file not found.

The header file does get generated, I can find it at:

DerivedData/Example/Build/Products/Debug-iphonesimulator/Example.framework/Headers/Example-Swift.h

I tried all of the upvoted solutions on Stack Overflow, none worked. The only fix is manually adding the directory to User Header Search Paths in build settings.

I must be doing something wrong though if other people don't have to manually add the header path. Also, when users of this framework include it as a pod, they need to do update the build settings as well, which I really want to avoid.

So, is there a solution to this that's not an ugly hack? I'm using XCode 9.0.1. I wish Xcode / iOS had a normal build system... coming from Linux/Android, I like many things about the iOS ecosystem but the build system is just ridiculous.

I've seen this problem in a mixed Objective-C/Swift framework and my solution was to include the module name as the directory part of the include. In your case it would be

#import "Example/Example-Swift.h"

instead of

#import "Example-Swift.h"

This is actually documented in the Importing Swift into Objective-C subsection of Importing Code from Within the Same Framework Target at https://developer.apple.com/library/content/documentation/Swift/Conceptual/BuildingCocoaApps/MixandMatch.html
