I followed this post when my project was complaining about not being able to find Crashlytics. It worked fine, and now the project actually compiles, but it now states:
ld: warning: directory not found for option '-F/pathtoproject...'
What exactly am I doing wrong? All I have in Framework Search Paths is $(inherited), $(SRCROOT) and the path to the project.
All I could think of was that I duplicated the project in order to test solutions and now the project folder is called "formerprojectname copy" but I tried adding copy to the project path in Framework Search Paths but it then couldn't find Crashlytics again.
How do I solve this issue? It's rather annoying.

I have a Objective C project and I want to add AdMob to it. Been following https://developers.google.com/admob/ios/quick-start#objective-c
I get the linker error
ld: warning: Could not find auto-linked framework 'FBLPromises'
Undefined symbols for architecture arm64:
"_OBJC_CLASS_$_UIScene"
I'm adding the frameworks manually. I dragged them in.
The tutorial doesn't say anything about the promises framework, but it comes in their download. And if I don't add it, I get a linker error saying a function is missing.
All of the frameworks are in the project and in Link With Binary Libraries list.
I tried deleting them and re-adding them, and quitting Xcode and clean build.
I tried adding framework search paths $(inherited) and $(TOOLCHAIN_DIR)/usr/lib/swift/$(PLATFORM_NAME) and the folder they are in with recursive $(PROJECT_DIR)/Frameworks and all of their exact paths individually also.
I tried adding a new swift file to the project so that it becomes hybrid.
I added -ObjC linker flag to Other Linker Flags, and $(inherited)
The tutorial says to add "GoogleUtilities.framework" But what I downloaded has "GoogleUtilities.xcframework" folder. So I tried adding the folder both as a group and as not, and I tried adding the framework files in the folder only.
I tried making a new project with nothing else.
Can anyone get AdMob to work on an Objective C project with adding frameworks manually?
I have agreed to the latest terms from apple and have a paid developer account.
I had a similar error in a Swift project.
Undefined symbol: _OBJC_CLASS_$_JSContext
In my case the solution was to add the JavaScriptCore.framework to the project.
Figured out the issue for a hybrid project!
The project I was linking to used an ObjC Bridging Header, so I simply needed to import Firebase in the header file:
// ObjC-Bridging-Header.h
#import "Firebase.h"
Not sure if this relates to a pure ObjC project, but you might be able to add a dummy Swift file to make it a hybrid project and use the bridging header.
I had the same error. I had forgotten to add the following libs: nanopb.xcframework, PromisesObjC.xcframework, UserMessagingPlatform.framework - included in GoogleMobileAdsSdkiOS.. I just added the missed libraries and now everything is OK.
Try to add libz.tbd, libc++.tbd, libsqlite3.tbd and StoreKit libraries in Link Binary With Libraries at the Build Phases tab.
I have managed to get react-native-fbsdk (core, login and share) all working in my project. I can build to devices without issue but if I try to create an archive from Xcode I get the error
Lexical or Preprocessor Issue
'RCTBridgeModule.h' file not found
I have followed the install instructions and create a virgin project and done it again to ensure nothing else could be causing this.
Similar Xcode related questions have come up blank for me too:
Xcode 4 can't locate public header files from static library dependency
When archiving app Xcode complains about missing files
Xcode 4 and nested projects -- header files not found
This makes me wonder if there's something else to to with FBSDK specifically that I need to do to get it to archive properly.
Has anyone got a project to archive with react-native-fbsdk? If so, how?
Note: I skipped the step regarding explicitly naming the path for static libraries as I do not know what the name should be; I do not know which the static library would be fbsdkcore (etc) or react-native/react.
I appears that the repo had an error in its header search paths in 'release' distribution. The fix was to correct the xcodeproj in the plugin (A PR is currently going through for this) as outlined here
The following line is present in the debug distribution but not in release for any of the required xcodeproj's
"$(SRCROOT)/../../node_modules/react-native/React/**",
Adding this fixes the error.

So, I've tired everything to get this to work after I've archived the application, but it keeps failing to open with the error message:
Dyld Error Message:
Library not loaded: /Library/Frameworks/RNCryptor.framework/Versions/A/RNCryptor
Referenced from: /Users/USER/Desktop/Project.app/Contents/MacOS/Project
Reason: image not found
I've added the Framework to the Copy Files Build Phase, I've changed the Runpath Search Paths to #loader_path/../Frameworks and the Framework Search Path to #executable_path/../Frameworks and it still doesn't want to open.
It opens fine in Xcode itself, but as soon as it's archived, it complains and doesn't run.
Any help is much appreciated :)
Ok, so I was able to fix it.
So the application was actually looking for the Framework in /Library/Frameworks/ on my Mac, I originally had thought it was looking for a reference in my actual .app file.
To fix it I opened up Terminal, cd' into the folder containing a copy of RNCryptor.framework and used this command
install_name_tool -id #executable_path/../Frameworks/RNCryptor.framework/RNCryptor RNCryptor.framework/RNCryptor
Then removed the old framework from the Xcode Project and re-inserted it using the Framework I just used from the directory I cd' into, and added the new Framework to the Copy Files Build Phase.
And voila, it worked :)
Working on my iPhone app and trying to build for debug and I get "106 duplicate symbols for architecture armv7"?
I am using the .workspace file because I am trying to use CocoaPods. If I don't use the .workspace and instead use the .xcodeproj I don't get the error, but then I get missing -lPods .
In my project I have the following targets in the Project Navigator.
Pods (blue icon)
MyProject (blue icon)
Restkit.xcodeproj (blue icon)
... all my files
The issue is that Restkit is making reference to "AFHTTPClient.h" and all the other AF code, but I included it via CocoaPods. I tried deleting the AFNetworking folder from the RestKit library, but apparently the Restkit library can't find the Pods version of AFNetworking?
Is there a way to get RestKit to use the Pods version? If not how do I go about removing Pods from my project?
There is a line in one of your .h files where your wrote
#include "___.m"
instead of
#include "___.h"
So I fixed it. After removing the RestKit version of AFNetworking, from the vendor folder, I added it back by dragging into Xcode. It asks which project I want it used/copied to and this time I selected RestKitTest (or whatever the RestKitTesting is named). It works now. Maybe I selected both RestKit and RestKitTest before, which was wrong?
I also came up with same error. Generally this kind of error occurs due to duplicate classes and xibs in project folder. For Example in my project I had these classes twice ServiceRequest.h/.m. Get rid of duplicate ones and you are good to go.
In Build Phases -> Compile Sources, make sure you don't have the same file added twice.
"Duplicate symbols for architecture" issue occurs in two situations:
You added a .m file twice into your project
You're using a static library (.a file) which already includes some classes that you include into the project.
For fixing any of those cases, check the linker error and look for the .o files that are duplicated (sample: Reachability.o).
Then go to the build phases -> compile sources and search the specified files, if any one appears twice delete one of them, if only appears once it means that the file is also included in one of the static libraries added to your project. Delete it from your list of sources to be compiled and try again.
I saw this error when, I did drag and drop my calabash framework onto xcode and selected add to targets option in the window thats shown. Basically there were two references to files added
I had to remove the calabash framework manually
Right way of doing it
copy to calabash framework to project directory
then go to xcode project
Choose target -> Build phases -> Link Binary With Libraries and add the frame work using + button
I have noticed that duplicate symbols are caused for Google analytics after installing cocoaPods as well. Once I removed one of archives, either libGoogleAnalytics_debug.a or libGoogleAnalytics.a duplication has gone. But obviously if I removed debug one I will not be able to run os simulator and vica versa. I know its not the solution, but at least it could give an idea what could be a solution. Will come back to this thread if I will figure out how to have both a files in this case.
Edit:
I was able to solve the issue by upgrading from G analytics version 2 to 3. It has only one library file and I guess this is the reason why we don't get duplicated symbols anymore. I hope it makes sense.
This question has evolved over the past several weeks to cover more general issues with xcode4 (and upgrading projects form older xcodes).
However many of the issues can be solved by following the same set of instructions.
If you have any of the following issues, try the methods in the accepted answer:
Xcode 4 fails to archive an App
Xcode 4 creates an unusable archive
Xcode 4 does not create an .ipa
Xcode 4 fails to compile due to preprocessor errors
Xcode 4 cannot find headers
Xcode 4's code complete is not working
Project dependancies won't compile
Adding a dependancy causes any of the above issues
Original Question
Title: "lexical or preprocessor issue file not found" in Xcode 4
I have a project in Xcode 4 that will build fine and run on the device and simulator but when trying to Archive it errors when looking for headers files associated with a static library:
In file included from /Volumes/Development/Path/LBProject/LBProject/LBProject-Prefix.pch:15:
In file included from /Volumes/Development/Path/LBProject/LBFDefines.h:23:
In file included from /Volumes/Development/Path/LBProject/Classes/LBProjectAppDelegate.h:11:
In file included from /Volumes/Development/Path/LBProject/LBProject/../FKNDirectory/FKNDirectoryManager.h:10:
/Volumes/Development/Path/LBProject/LBProject/../FKNDirectory/FKNDataModel.h:11:9: fatal error: 'Merchant.h' file not found [1]
#import "Merchant.h"
^
1 error generated.
Xcode gives the error
lexical or preprocessor issue file not found
Much Googling has show many people are having this issue but no solution. Anyone got a fix or even a clue.
Update: The user header search paths are set to ${BUILT_PRODUCTS_DIR} in all configurations. It builds fine using any configuration except when archiving.
Update 2: Merchant.h is a Core Data class that is auto-generated and therefore inside .xcdatamodeld package, however the headers are all copied to the public headers directory when the library is built.
NB: The steps below will solve 90% of your Xcode archive issues
however, from the comments it is suggested you try quitting Xcode
first. This may save you hours of setting tweaking.
Check the "user header paths" are correct (Add "" to paths for spaces, both in your project and dependencies)
Set "Always search user paths" to YES
Create a group call "Indexing headers" in your project and drag the headers to this group, DO NOT add to any targets when prompted. This includes any headers inside your .xcdatamodeld, you'll need to right-click and view package contents to find them.
For all dependencies set "Skip Install" build setting to "Yes"
Moving any "Public" headers in Build Phases to "Project"
Set the Build Setting "Installation Directory" on your Target to $(LOCAL_APPS_DIR)
Change the target build setting "scan all source files for includes" to YES. (link)

Manually delete the project.xcworkspace files form all referenced projects
I had the same problem in XCode 4: "Lexical or preprocessor issue MyFile.h not found". However, MyFile.m was not a static library, just a standard class. And MyFile.m and MyFile.h were included properly and indexed in the project.
So ... I quit XCode and the Simulator, then restarted them and the problem disappeared.
I found that the problem went away when I changed the target build setting "scan all source files for includes" from no to yes.
I was able to resolve this issue without any changes to any of the build settings by simply copying the .h files into the Project's directory in the finder. I did NOT add them to the project at all. Just having them in the project's filesystem directory seemed to be enough to allow Xcode's implicit linking to work properly. More details here.
I had a weird issue like this. Changing "Scan all resource files..." to Yes didn't help. I took a look at the Framework Search Paths and noticed that I had
$(inherited)
"$(SRCROOT)"
"$(SRCROOT)/my/correct/path"
It seemed right but was still failing. I then tried rearranging the order of 2 & 3 and all of a sudden it built fine. So not sure why that was the hickup, but wanted to add it to the list of things to try in case it helps someone else.
My solution was to change my
#import "HeaderFile.h"
to
#import <FrameworkName/HeaderFile.h>
and everything started working again.
What was unusual was that it had stopped working suddenly after building
a few times.
The problem resolved itself when I set
Build Settings->Project->Search Paths to Yes
I had the same — 2 targets in my project (Project and ProjectTest of GHUnit). When my scheme was set up to Project, the import of <GHUnitIOS/GHUnit.h> was problem of “lexical or preprocessor issue file not found”. But when I set as a scheme ProjectTest, everything was OK. So, I have added GHUnitIOS.framework in Project too.
Looks like your header search paths are incorrect not configured properly in your build settings for the active scheme. Verify them and update your question with the current setting.
I'm having similar issues on the simulator but not the device and my header search path fields are empty (Seems to be default). But changing Workspaces seems to have solved the issue. Maybe you could try creating a new Workspace, add your project to it and see if that helps. Now I'm investigating why.
I was getting this "file not found" error for one particular .h file in my project. I resolved the issue by removing that .h file from the project (selecting "Remove references") and re-adding it.
Adding on more variant: I had two instances of foo.m in the Compile Source build phase, which some how caused "Header not found" for foo.h.
Another chance:
In workspace project: watch in the Target for section Build Phases. As many manuals says you need to have a Copy Files Build Phase to copy all your headers to another place, as iOS Framework cannot contain header files to be shared (this is my case).
Choose for those Copy Files as Destination option "Products Directory". Or another directory of your like where the headers will reside.
That worked for me. Probably the build for Archive (or Release) directory is very different than expected in build for Debug .
Also check in your workspace settings your build directory.
XD
For me, this issue occurred after I added new files to the project; a blank .m and .h derived from NSObject. Here's how I resolved it:
Closed and restarted xCode
Deleted the two new files via XCode
Recompiled successfully
I then Re-added them afterward and it also worked.
Definitely a bug in xCode...
