I have included SDwebimage architecture for lazy loading of image in table view.Can any tell me what is the issue?

Answer 1

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.

Answer 2

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

Answer 3

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!

Answer 4

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.

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.

Answer 6

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').
