Facebook iOS8 SDK build module error for FBSDKCoreKit

Question

I am trying to add the Facebook SDK to my iOS 8 Objective-C app in Xcode. I did the install according to the FB-dev instructions. However, I get a "Could not build module 'FBSDKCoreKit'" error when I add the header to my AppDelegate.m file.

#import "AppDelegate.h"
#import <FBSDKCoreKit/FBSDKCoreKit.h>

Based on what I read elsewhere

1. I have already cleaned the build and re-installed Xcode.
2. I also re-installed the Facebook SDK installer and tried to add it to a blank project (in case there was something corrupt with my app).
3. I have double checked the plist and the framework files FB lists in the instructions, but nothing has seemed missing.

I'm stumped.

Answer 1

FBSDKCoreKit can't be built because of "include of non-modular header inside framework module" error in FBSDKAppLinkResolver.h header file: in #import <Bolts/BFAppLinkResolving.h> line.

The solution from Swift compiler error: "non-modular header inside framework module" (switching CLANG_ALLOW_NON_MODULAR_INCLUDES_IN_FRAMEWORK_MODULES = YES) did't help me.

My solution:

1. Create in Bolts.framework file module map: Modules/module.modulemap (like in FBSDKCoreKit.framework)

2. Put such code inside

   framework module Bolts {
   umbrella header "Bolts.h"
   
   export *
   module * { export * }
   
   
   explicit module BFAppLinkResolver {
       header "BFAppLinkResolver.h"
       link "BFAppLinkResolver"
       export *
   }}
   

Interesting fact is that in FBSDKCoreKit such scheme is realized by Facebook, why didn't they apply it into Bolts...
