Question

I am using Xcode 6   1  Firstly I am creating a dynamic library  CoreLibrary   This library contain RequestPoster h file   2  Then I create a Cocoa Touch Framework and added this dynamic library  CoreLibrary    3  Then this framework is add on my project and it gives error in RequestPoster h file  CoreLibrary    Error   Include of non-modular header inside framework module class    ifaddrs h  arpa inet h  sys types h   These file not found in the project

If you need this for CocoaPods targets add this lines in Podfile   post install do  installer    installer pods project targets each do  target      target build configurations each do  config        target build settings config name   CLANG ALLOW NON MODULAR INCLUDES IN FRAMEWORK MODULES      YES      end   end end

I came across this issue as well and originally thought it was a CocoaPods issue  but it was an issue in the apps build settings where someone  probably me  had set   PODS ROOT  in Header Search Paths and set it to be a recursive search   This was allowing it to find headers that were not intended to be used when building the app   Once I set this to use non-recursive everything was fine   using recursive search is a terrible hack to try to find the proper headers  Lesson learned

You can set Allow Non-modular includes in Framework Modules in Build Settings for the affected target to YES  This is the build setting you need to edit     NOTE  You should use this feature to uncover the underlying error  which I have found to be frequently caused by duplication of angle-bracketed global includes in files with some dependent relationship  i e      import  lt Foo Bar h gt     referred to in two or more dependent files   If setting Allow Non-modular includes in Frame Modules to YES results in a set of  X is an ambiguous reference  errors or something of the sort  you should be able to track down the offending duplicate s  and eliminate them   After you ve cleaned up your code  set Allow Non-modular includes in Frame Modules back to NO

Make sure the header files are publicly available as part of the framework s public headers    Goto Framework -  Target -  Build Phases and drag to move the relevant header files from Project to Public  Hope that helps

I was able to clear dozens of these errors by using Git clean   Here s the command   git clean -dffx  amp  amp  git reset --hard

In case if you are developing your own framework  WHY is this happening  If any of the public header files you have mentioned in your module modulemap have import statements that are not mentioned in modulemap  this will give you the error  Since it tries to import some header that is not declared as modular  in module modulemap   it breaks the modularity of the framework  HOW can I fix it  Just include the header that gave the error to your module modulemap and build again  WHY NOT just set allow non-modular to YES  Because it s not really a solution here  with that you tell your project  quot this framework was supposed to be modular but it s not  Use it somehow  I don t care  quot  This doesn t fix your library s modularity problem  For more information check this archived blog post or refer to clang docs

This was kind of an annoying issue for me  No suggestions seemed to help my particular case  since I needed to include the  non-modular  headers in my individual file header file  The work around I used was sticking the import call in the prefix header file

I ended up moving the Umbrella Header to bottom of the Headers list after checking the above solutions  and that worked in Xcode 9 3

the same problem make crazy finally  i find put the  import xxx h  in implementation instead of interface can fix the problem And if you use Cocoapods to manager your project you can add      s user target xcconfig      CLANG ALLOW NON MODULAR INCLUDES IN FRAMEWORK MODULES      YES      in your  xxx podspec  file

I had this problem when I added Swift source code to an existing ObjC static framework  dynamic framework with Mach-O type  quot Static Library quot    The fix was setting CLANG ENABLE MODULES   quot Enable Modules quot  in build settings  to YES

I solved it removing Modules folder from the framework    Browse to your framework location which is present in the App Project using finder  Go inside Test framework folder  In the above case it will be CoreLibrary framework   amp  Delete Modules folder   Clean and Re Build the app  it will solve the problem

I had the same problem and solve it by just making header file public     If you are working on multiple modules in your project  Then your header file needs to be public to be used in other parts of projects  What you need is to select that header file  and in project Utilities view  Change the file from Project Private to Public  See image below

If you see this error in an umbrella header when building a dynamic framework  make sure you import your file as    import  MyFile h   and not as  import  lt MyFramework MyFile h gt

I was having a similar problem  When running my app target  everything was working fine  but when changing to test target and trying to run the tests   quot Include of non-modular header inside framework module quot  error showed up  I tried all the solutions posted here but none of them worked  At the end I scrolled over all build settings and for each one that was related to headers I read the description  Switching USE HEADERMAP to NO did the trick  I hope anyone could find this helpful

I had the same issue and nothing from above helped me  So I hope my answer will be helpful for somebody  In my case the problem was in ALWAYS SEARCH USER PATHS setting  When it was set to NO project built and worked ok  But as far as one of the pod required it to be set to YES I was receiving an error     Include of non-modular header inside framework module   After couple cups of coffee and all day researching I found out that according to known issues of Xcode 7 1 Beta 2 release notes          If you get an error stating  Include of non-modular header inside   framework module  for a framework that previously compiled  make sure   the  Always Search User Paths  build setting is set to  No   The   default is  Yes  only for legacy reasons   22784786    I was using XCode 7 3 though  but seems like this bug hasn t been fixed yet

Include of non-modular header inside framework module   When you get this error the solution in some circumstances can be to simply to mark the file you re trying to import as  public  in the file inspector  Target Membership    The default is  Project   and when set this way it can cause this error   That was the case with me when trying to import Google Analytic s headers into a framework  for example

Try going  Build Settings under  Target  and set  Allow Non-modular Includes in Framework Modules  to YES   The real answer is that the location of the imports needs to be changed by the library owner  Those files ifaddrs h  arpa inet h  sys types h are getting imported in a  h file in a framework  which Xcode doesn t like  The library maintainer should move them to a  m file  See for example this issue on GitHub  where AFNetworking fixed the same problem  https   github com AFNetworking AFNetworking issues 2205

Actually an easier way to fix this is to move the  import statement to the top of the  m file instead  instead of having it in your  h header file   This way it won t complain that it s including a non-modular header file  I had this problem where Allow non-module includes set to YES did NOT work for me  so by moving it to the implementation file  it stopped complaining  This is in fact the preferred way of importing and including header files anyway  Once you ve done this  setting this back to NO should work   Ideally we should try and aim to have Allow non-module includes set to NO  Setting this to YES in most cases means you re doing something wrong  The setting translates to  Allow importing random header files on disk that aren t otherwise part of the module   This applies to a very few use cases in practice  and so this setting should always be NO  i e  the default value

Allow Non-modular Includes in Framework Modules only work in objc code  not work in swift    After a period of research  I found that swift can pass warning parameter to clang  so set OTHER SWIFT FLAGS to -Xcc -Wno-error non-modular-include-in-framework-module inhibit swift import error    just for someone who have same problem
