When encountering a large number of duplicate symbol _OBJC_CLASS_ errors during an iOS app build
After updating CocoaPods and building the project, I encountered a linker error. Upon examining the message, I noticed a large number of duplicate symbol _OBJC_CLASS_$_ errors.
→ Check the project's Build Settings → Other Linker Flags.
-ObjC -l"Pods-AFNetworking" -l"Pods-MBProgressHUD" -l"Pods-SDWebImage" -all_load ...
Remove all instances of -l"Pods-library name".
-ObjC -all_load ...
It should look like this.
Build the project. → OK
