iOS - Build fails with CocoaPods cannot find header files

Question

I have an iOS project using CocoaPods  Everything was working smoothly until another developer started to work on the same project  He made some changes  only to code as far as I know  and made a new branch in the repo  I have checked out his branch and tried to build it  but I am getting an error  ASLogger ASLogger h file not found    Even if I delete the whole project and make a fresh copy and use  pods install    the build failure is still there  Do you have any idea where the problem can be  If you need some more infos  just ask

I was on the GM seed of Xcode 5 0 and I couldn t get any of these answers to work   I tried every single answer on SO on multiple different questions about header imports w  cocoapods   FINALLY I found a solution that worked for me  I upgraded to Xcode 5 0 via the Mac AppStore  installed on top of the GM seed  and now the header imports are working as expected     I also still had a beta version of Xcode 5 on my system and I deleted that as well   Maybe it was a combination of the two things  but hopefully this helps someone else

I have got the same problem  but the above solutions can t work  I have fixed it by doing this    Remove the whole project Run git clone the project and run the bundle exec pod install cd the peoject and run remote add upstream your-remote-rep-add git fetch upstream git checkout master git merge upstream master   And then it works

I found   PODS HEADERS SEARCH PATHS  is missing and it is not defined in my develop git branch  So I added     SRCROOT  Pods Headers   for Header Search Paths with recursive  That is ok for me

None of the answers helped me  I had my pods linked with all targets  build configurations setup properly  correclty set search paths    inherited    etc       Problem disappeared by itself after I updated cocoapods to the newest  debug version using standard install   update command      gem install cocoapods --pre   or      sudo gem install cocoapods --pre    if sudo was used during installation    It must have been cocoapods bug

Here s what worked for me   Go to the Target    Build Settings  tab and find the  User Header Search Paths  setting    Set this to    BUILT PRODUCTS DIR   and check the  Recursive  check box    Now the built target will search the workspace   s shared build directory to locate the linkable header files         UPDATE  I had a similar  although slightly different  problem recently  It turned out Xcode couldn t find the Pods because I had opened up the  xcodeproj file rather than the  xcworkspace file  Might help others in the future

The wiki gives an advice on how to solve this problem      If Xcode can   t find the headers of the dependencies       Check if the pod header files are correctly symlinked in Pods Headers   and you are not overriding the HEADER SEARCH PATHS  see  1   If Xcode   still can   t find them  as a last resort you can prepend your imports    e g   import  Pods SSZipArchive h

For me  what fixed it was the iOS deployment target for my Pods project was lower than my project itself  Once I made it the same as my project it was able to find the header file

I think an ultimate solution is to go to Build settings - gt  Search Path - gt  User Header Search Paths  find your library path and go through it in a Finder  Make sure that all path exists including your import path   For me my path was shorter than in a tutorial  In tutorial it was something like  import  lt SDK path to sdk File h gt   but turns out it is just  import  lt SDK File h gt

1 Check      build settings -  Search Path -  User Header Search Paths -        PODS ROOT     recursive          2 Check import style KEY POINT    if your s podfile have set  use frameworks   In yours File-Bridging-Header h the formatter should like this    import  MBProgressHUD h   else should be below   import  lt MBProgressHUD h gt   3 That must be work  trust me

If you had the building errors after a  pod install  or a  pod update   it may be that one of your pods have been built with XCode 6 3 while you are still using a previous version    In my case I had to update my OSX from mavericks to Yosemite to have Xcode 6 3 and solve the problem

User · Answer

for me the problem was in Other Linker flags value  For some reason I had no quotes in flags like -l xml2  -l Pods-MBProgressHUD

Both other answers didn t help here  I found 2 other problems that might fix it    The Project- Info- Configurations in the Xcode project  your project  should be set to  Pods  for Debug  Release  and whatelse you have   See  Headers not found     search paths not included  Maybe you have to link the target with the link with command  See  Unable to find headers in Static Library project    EDIT  You can check a symlink this way  create a textfile named  check  without an extension  copy these lines into it   file  Users youUserName XcodeProjectName Pods BuildHeaders SVProgressHUD SVProgressHUD h if      -e  file  amp  amp   -L  file     then   echo   file symlink is  broken   else   echo  symlink works  fi   Then go to the terminal  change to the folder where your check file is located and type  bash check

One simple workaround is   1  Delete Pods folder and Podfile lock file  But don t delete Podfile 2  Run following command in your project root folder   pod install

I had to download the zip from git hub and drag the missing files into the Finder at corresponding paths in Pod

Have a try to comment this line for your target     use frameworks    Or you can refer to my another answer  added unit testing target to xcode - failed to import bridging header won  39 t go away

I ve found that including the library as a pod install directly helps dynamic libraries  For example  for Firebase   pod  RNFirebase    path   gt   path to node modules react-native-firebase ios    Or for ASLogger   pod  ASLogger    path   gt   path to node modules aslogger ios     path to header files   Changing or hardcoding HEADER SEARCH PATHS did not help me  If the error ever recurs  it s not necessary to rm -rf node modules nor delete the pod file etc  I found it useful to clear the cache   For react-native  I run       rm -rf  TMPDIR react-native-packager-cache-      rm -rf  TMPDIR metro-bundler-cache-      rm -rf  TMPDIR metro-       rm -rf  TMPDIR react-       rm -rf  TMPDIR haste-      rm -rf    getconf DARWIN USER CACHE DIR  org llvm clang ModuleCache      npm start -- --reset-cache   For Xcode I remove folders in   Library Developer Xcode DerivedData

I will update the below things in my Build settings and I did not get any errors  To check these are the things while updating your cocoapods   Build Settings     Enable Bit code - YES if you are using bitcode       Macro preprocessor -   inherited       Other linker flag - objc  -lc      inherited    Build architecture only     Debug - Yes      Relese - No   Search Path     Framework search path -   inherited    PROJECT DIR       Library search path -   inherited       Header search path -   inherited

Update  I ve updated this since my original answer  that got the downvote  so I hope this helps  And if it does  hopefully it will get my vote back   If the headers aren t being imported  you probably have a conflict in the HEADER SEARCH PATHS  Try and add   inherited  to the header search paths in your Build Settings to make sure that it pulls in any search paths included in the  xcconfig file from your CocoaPods   This should help with any conflicts and get your source imported correctly

What worked for me was selecting the Pods project  finding and selecting the target framework with the missing header in the Pod project s target directory and setting  Build Active Architecture Only  to  No  under  Architectures  in the target s build settings

Here s another reason  All the header paths seemed fine  but we still had an error in the precompiled   pch  file trying to read a pod header    i e   import  lt CocoaLumberjack CocoaLumberjack h gt      Looking at the raw build output  I finally noticed that the error was breaking our Watch OS Extension Target  not the main target we were building  because we were also importing the  pch precompiled header file into the Watch OS targets  and it was failing there   Make sure your accompanying Watch OS target settings don t try to import the  pch file  especially if you set that import from the master target setting  like I did

I was the only developer in the team experiencing this same issue  it worked perfectly for everybody so I realized it had to be my environment  I tried a git clone of the same project in another directory and it compiled perfectly  then I realized it had to be Xcode caching stuff for my project path somewhere  that  somewhere  is the DerivedData folder  just remove it and do a clean build of your project  it worked for me   You can get the path and even open the folder in finder by going to   Xcode -  Preferences -  Locations -    DerivedData

Header files  you ll be the death of me     Finally got it to work by adding  including quotes       PODS ROOT  BuildHeaders    to the User Header Search Paths entry  and checking  recursive

Update  Make sure your Podfile includes link with on targets missing a config file  Cocoapods only sets the first target by default otherwise  e g   platform  osx   10 7  pod  JSONKit            gt  1 4   link with  Pomo    Pomo Dev    Pomo Tests    ------ End Update    Note  Please do note that you have to look into Project- Info- Configurations for steps below     I had similar symptoms and found that the pods xcconfig file was not being included in the specific target I was trying to build   Some of the other suggested solutions worked for me  but this one seemed to address part of the underlying issue     The simple solution was to change set the configuration file for the targets that didn t have one set

If none of the above worked for you and you are finding this error because you just switched to use frameworks  in your Podfile  read on    I tried all the solutions above and a lot more before learning that it isn t about search header paths at all in my particular case  it s that when you switch to use frameworks  in your Podfile you no longer need to include frameworks in your bridging header  and in fact Xcode will throw the very unhelpful  unable to find header  error    What you need to do is remove all imports from your bridging header file  and instead use the Swift import Module in your individual Swift files as needed  just like you would for Swift frameworks    AND if you are using any of the framework headers in your Obj-C classes  in my case we have a convenience class that used the FBSDK  you need to change it from a local to global import  this means change  import  Module h  to  import  lt Module Module h gt   which should autocomplete for you when you begin to type the framework name  In my case it was  lt AFNetworking AFHTTPRequestOperationManager h gt     Edit  I ve since learned that doing an  import Module uses the umbrella file which is even safer

This was the answer for me  I updated cocoapods and I think that made the PODS HEADERS SEARCH PATHS go away  My solution was similar to this but I used    PODS ROOT  Headers       Andrew Aitken   Thank you so much for this answer  I had a hard time looking for ways to fix my problem  Thank you very much
