AFNetworking won't compile

I'm totally stuck trying to run a project on the simulator using AFNetworking. I've used this dependency before on other projects, so I don't understand what is going wrong here. First, the error when I try to run the project:

Undefined symbols for architecture x86_64:
  "_OBJC_CLASS_$_AFHTTPSessionManager", referenced from:
      _OBJC_CLASS_$_SharedNetworkObject in SharedNetworkObject.o
  "_OBJC_CLASS_$_AFJSONResponseSerializer", referenced from:
      objc-class-ref in SharedNetworkObject.o
  "_OBJC_METACLASS_$_AFHTTPSessionManager", referenced from:
      _OBJC_METACLASS_$_SharedNetworkObject in SharedNetworkObject.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm sure that this is part of the problem, but I don't know how to resolve it:

enter image description here

This is the offending .h file:

#import <Foundation/Foundation.h>
#import <AFNetworking/AFNetworking.h>
#import "SharedSessionKey.h"

@interface SharedNetworkObject : AFHTTPSessionManager

+ (SharedNetworkObject *) sharedNetworkObject;   // class method to return the singleton object

@end

It may be of interest to note that when I start typing the import line for AFNetworking, the line fills in after a few characters, so I know that there is some awareness of the presence of the AFNetworking dependency.

I installed the dependency using CocoaPods. Here is my Podfile:

# Uncomment this line to define a global platform for your project
platform :ios, '8.0'

source 'https://github.com/CocoaPods/Specs.git'

target 'WeRun' do
pod "AFNetworking", "2.5.2"
end

target 'WeRunTests' do

end

And, of course I am working in .xcworkspace (not .xcodeproj).

One more thing, my xcconfig file looks like this, which matches with other successful AFNetworking builds:

GCC_PREPROCESSOR_DEFINITIONS = $(inherited) COCOAPODS=1
HEADER_SEARCH_PATHS = "${PODS_ROOT}/Headers/Public" "${PODS_ROOT}/Headers/Public/AFNetworking"
OTHER_CFLAGS = $(inherited) -isystem "${PODS_ROOT}/Headers/Public" -isystem "${PODS_ROOT}/Headers/Public/AFNetworking"
OTHER_LDFLAGS = -ObjC -l"Pods-MyApp-AFNetworking" -framework "CoreGraphics" -framework "MobileCoreServices" -framework "Security" -framework "SystemConfiguration"
OTHER_LIBTOOLFLAGS = $(OTHER_LDFLAGS)
PODS_ROOT = ${SRCROOT}/Pods

I don't know what else to look for. I've completely removed the pod and reinstalled, only to find the exact same error. Can anyone help me figure this out? Thanks!

Solution

  • I spent a couple of hours fighting with this exact same issue, going through all the Google hits I could find. Building for the device was working, but building for the simulator was not.

    Here are the steps that finally solved the issue for me:

    1. Clear the XCode caches: 

      rm -rf ~/Library/Developer/Xcode/DerivedData/

    2. Clear the CocoaPods caches and reinstall the dependencies:

      rm -rf "${HOME}/Library/Caches/CocoaPods"
rm -rf "`pwd`/Pods/"
pod update

    3. Finally go to the "Pods" project and set the Build Active Architectures Only to No also for the "Debug" configuration.
