Swift Framework: Umbrella header '[…].h' not found

Question

In a custom framework containing both Objective-C and Swift code, the Swift compiler throws the following error:

[build_pat         


        

Answer 1

If you're using Xcode 7.1 and CocoaPods 0.39, there seems to be a swift compiler change that affects some CocoaPods (Nimble, Quick, etc.) Try some of the solutions specified in the this thread: https://github.com/CocoaPods/CocoaPods/issues/4420 however, if neither of them work, try using Xcode 7.0.1 or 7.2 beta. You can get both of them here: https://developer.apple.com/downloads/.

Edit: In my case, to fix the issue, I also had to downgrade CocoaPods to 0.38.2.

Later edit: It seems not to be related to Xcode 7.1. Just downgrading CocoaPods to 0.38.2 should help:

sudo gem uninstall cocoapods -v 0.39
sudo gem install cocoapods -v 0.38.2

Answer 2

make sure "import paths" in Build Settings includes the file you're trying to include...

Answer 3

I fixed it by making the Compilation Mode of the problematic framework build settings to Incremental.

Answer 4

In my case problem was caused by remove headers script in Build Phases

function removeHeaders() {  
    find $BUILD_ROOT/...  -name '*.h' -exec rm -f {} \;  
}  
removeHeaders

Deleting this script fixed the problem.

Answer 5

One more solution: After renaming a folder, the old location might still be listed in the project file for the .h file, even if you updated the location via Xcode's side-bar. This old location causes the umbrella-header error.

Simple solution: Remove the reference to the .h file, and re-add. (and then remember to make it public again!)

Answer 6

Your header file needs to be in the [Build Phases/Headers/Public] section.

If your header file is already in the [Build Phases/Headers/Public] section, many times doing the fallowing solved my problem:

1. clean the project
2. move the header file to the "private" or "project" section
3. move the header file back to the "public" section
4. rebuild everything again
