[iphone] lexical or preprocessor issue file not found occurs while archiving?

I am new to this iPhone development and i have almost completed my first application but when i try for creating an archive it gives an error lexical or preprocessed issue file not found But it runs fine in simulator and also has also tested on device. I have included SDwebimage architecture for lazy loading of image in table view.Can any tell me what is the issue?

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.

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.

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.

The new version contain fix for this, feel free to update. Or you can just replace

#include "iPhone_View.h"

with

#if UNITY_VERSION < 450

#include "iPhone_View.h"

#endif

I fixed mine. The fb sdk downloaded (from my browser) as 'FacebookSDKs-iOS-4.22.0' -- I just had to rename the folder to FacebookSDK. So now in Build

Settings --> Framework Search Paths

the path looks something like /Users/.../Documents/FacebookSDK (where as before it was /Users/.../Documents/FacebookSDKs-iOS-4.22.0) Hope this helps!?

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.

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 :(

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.

I had this problem after changed project name. I used all the methods mentioned on the internet but still doesn't work. Then I realized that all the header files not found was from cocoapods, so I re-installed the cocoapods using pod install, and thus solved the problem.

Hope this could help.

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/ && npm install

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.

Delete the unit testing from your project follow the below steps this will solve the issue.

select your project from the project navigator to open the project editor. From the target delete the test from the left side of the project editor and press the Delete key.
