I had this same issue now and found that my sub-projects 'Public Header Folder Path' was set to an incorrect path (when compared with what my main project was using as its 'Header Search Path' and 'User Header Search Path').

e.g.

My main project had the following:

Header Search Paths
- Debug "build/Debug-iphoneos/../../Headers"
- Release "build/Debug-iphoneos/../../Headers"

And the same for the User Header Search Paths

Whereas my sub-project (dependency) had the following:

Public Header Folder Path
- Debug "include/BoxSDK"
- Release "include/BoxSDK"

Changing the 'Public Header Folder Path' to "../../Headers/BoxSDK" fixed the problem since the main project was already searching that folder ('../../Headers').

PS: I took some good screenshots, but I am not allowed to post an answer with images until I hit reputation 10 :(

Spaces in a folder name in your header search path can cause this problem  Make sure the folders in your project do not have spaces in their names

I know this is old  but I m gonna chime in anyway because it may be useful to someone  If you can still see the file in Finder  then click on the file in your project and delete it  selecting  remove references  and not  move to trash    Once the reference is removed  drag and drop the file from finder into your project again and it should sort itself out

For what it s worth  my problem was completely unrelated to the error Xcode was giving  I stumbled onto a solution by deleting the  h reference  compiling  adding the reference back and compiling again  The actual error then became evident

Just adding another thing that worked for me    react-native link   Evidently my ReactNative files were no longer there  I could figure that out by clicking on      Build Phases -  Link Binary with Libraries -     Then right clicking a file I knew was responsible for React  and clicking Show In Finder    But nothing opened  So assuming the library went missing  I just ran the above command which relinked everything again   Also if you havn t  try    rm -rf node modules   amp  amp  npm install

My project was building fine until I updated to Xcode 10 1  After the Xcode update  started getting Lexical or preprocessor Issue errors on build  Some XCDataModel header files could not be found   This fixed the issue   Go to Build Settings  Header Search Paths Change the appropriate value from   SRCROOT  non-recursive to recursive   This ensures that subfolders are also searched for headers during build

This happened to me after I renamed a file   For some reason it was still looking for the file with the old name   What I did was create the file that it was complaining about and added to the project   Then I did a Project- clean  then Project- Build and verified the error was gone   Then I selected the newly added files and deleted them  This removed all references and I no longer see the error

Few things to try  Ensure the Framework and all it s headers are imported into your project properly   Also in your Build Settings set YES to Always search user paths  and make sure your User header paths are pointing to the Framework   Finally  Build- Clean and Restart Xcode   Hope this helps    UPDATE  According to SDWebImage s installation  it s required you make a modification to Header Search Path and not User header paths  As seen below     Have you done this as well  I suggest slowly  re-doing all the installation steps from the beginning

In my case I was developing a framework and had a test application inside it  what was missing is inside the test application target -  build settings -  Framework Search Paths    The value needed to be the framework path  the build output -  framework  which is in my case       FrameworkNameFolder    -  the 2 points indicates to go one folder up      Also  inside the test application target -  Build Phases -  Link Binary With Libraries    I had to remove the framework file  clean the project  add the framework file again  compile and this also solved the issue
