I'm running to the same issue. 6.9.4 works fine though.

Tried to clean derived data? or remove the plugin, clean the pods and install it again

[viet-nguyen-1926]

@amit-kremer93
Yes, I always delete it every time I build
I have removed plugin then install again then check again but still have bug there

rm -rf ~/Library/Developer/Xcode/iOS DeviceSupport
rm -rf ~/Library/Caches/com.apple.dt.Xcode
rm -rf ~/Library/Developer/CoreSimulator/Caches
rm -rf ~/Library/Developer/Xcode/DerivedData
rm -fr ios/Pods
rm -fr ios/Podfile.lock
cd ios && pod repo remove trunk&&pod install --repo-update

@viet-nguyen-1926 did you manage to solve it?

[viet-nguyen-1926]

@amit-kremer93
Not yet, Now im using 6.9.4 to avoid that issue for releasing.
Not only my app, my friends also have the same.

Which RN version and xcode do you use?

[amit-kremer93]

Try to open Xcode and go to Pods->Development Pods->react-native-appsflyer. Then open the file RNAppsFlyer.h and replace the import statements:

#if __has_include(<AppsFlyerLib/AppsFlyerLib.h>) // from Pod
#import <AppsFlyerLib/AppsFlyerLib.h>
#else
#import "AppsFlyerLib.h"
#endif

just with:
#import <AppsFlyerLib/AppsFlyerLib.h>

@amit-kremer93
I have checked in RN 0.71.6 and Xcode 14.3
I have followed your instructions but the error is still there.
I tried another way, I just changed the import path in AppDelegate from #import "AppsFlyerLib.h" to #import <AppsFlyerLib/AppsFlyerLib.h> so i can build normally without any errors

What do you think about this way?

[ray-step]

@amit-kremer93 I tried the recommended change and it did not help. I also tried 6.10.3 which seemingly has this change and that one throws the same error.

My RN is 0.71.8, and my Xcode is 14.2.

[amit-kremer93]

@viet-nguyen-1926 Do you import AppsFlyerLib.h and RNAppsFlyer in your AppDelegate.m?

[viet-nguyen-1926]

@amit-kremer93
No, i dont.
just only import AppsFlyerLib.h in AppDelegate.h

This is still an issue. I attempted the above solutions with no luck. I also tried a solution in this issue thread where we set the No Common Blocks setting to NO which also didn't work. After digging deeper into the build error I found that a previous definition is linked, which is an identical AppsFlyerLib header file, located in a folder called headers. If I try deleting this folder, it gets recreated on build. My knowledge of Xcode and the pod environment stops me here unfortunately, but hopefully this helps reach a solution.

Any help here would be greatly appreciated.
