I downloaded the new iOS Parse API (1.6.4) and tried to build my project. When I do, I get this error:
Undefined symbols for architecture arm64" "_BFTaskMultipleExceptionsException", referenced from:
___53+[PFObject(Private) deleteAllAsync:withSessionToken:]_block_invoke214 in Parse(PFObject.o)
___65+[PFObject(Private) _deepSaveAsync:withCurrentUser:sessionToken:]_block_invoke311 in Parse(PFObject.o)
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Temporary workaround for Parse 1.6.4 and Facebook SDK 3.23:
Add to your AppDelegate.m or another class following constant after imports and before implementation section:
NSString *const BFTaskMultipleExceptionsException = @"BFMultipleExceptionsException";
@interface IPAppDelegate ()
@end
@implementation IPAppDelegate
It should solve the problem until it'll be solved on Parse/Facebook side.
-- Update: This solution is only for Facebook and Parse SDK versions that listed above and these versions right now are outdated.
New Parse SDK 1.7.4 works correct with new Facebook SDK 4.0 and there shouldn't be such a problem.

I was able to figure out the URL for anyone that needs Parse iOS v1.6.3.
https://parse.com/downloads/ios/parse-library/1.6.3
I can confirm that everything compiles properly using 1.6.3.

Placing
NSString *const BFTaskMultipleExceptionsException = @"BFMultipleExceptionsException";
in the App Delegate as suggested by Sergey Surkov in between the imports and the implementation and then adding libstdc++.6.dylib in build phases worked for me. Please also view https://stackoverflow.com/a/27628797/1036945

I've had the exact same problem using the latest SDKs from Parse (1.7.4) and Facebook (4.2.0). The problem is caused by the Bolts.framework included in both Parse and Facebook SDKs. For some reason the Bolts framework in Parse is always newer than the one included in the Facebook SDK.
After many-many attempts at installing, removing and re-installing these SDKs, using the drag and drop method and via Cocoapods, I finally managed to overcome this issue by undertaking the following steps:
- I removed completely any instance of the Parse, Facebook and Bolts frameworks from my project;
- I re-added the FBSDKCoreKit framework (and the ShareKit and LoginKit for the needs of my project) following the steps on the Facebook developer page: https://developers.facebook.com/docs/ios/getting-started/ Make sure NOT to copy the items to your project.
I re-added the Parse framework to the project using the drag-and-drop method. I also added the ParseFacebookUtilsV4 framework because I needed it to create users via Facebook Login.
This was the most important step that solved everything: I added the Bolts.framework provided by Parse by dragging it to the project, but making sure NOT to copy it to the project (just like with the FBSDKCoreKit framework, I deselected the "Copy items into destination group's folder." option. If you copy it to the project folder, the project won't build.
These steps finally solved all my problems.

if you are using cocoapods try pod update Bolts

EDIT2: FacebookSDK Update 3.23.2 resolves this issue and includes Bolts 1.1.4: https://developers.facebook.com/resources/facebook-ios-sdk-3.23.2.pkg
EDIT: Drop -ObjC "Other Linker Flag" from your Build settings.
Bolts.framework is not necessary with Parse if Facebook SDK is integrated.
As of Facebook iOS SDK 3.14 bolts.framework is included. https://developers.facebook.com/docs/ios/upgrading-3.x
Try removing your manual instance of bolts.framework.

Just to put the record straight.
The issue is caused because of a conflict with the Bolts framework between the Facebook SDK Bolts and the Parse bolts framework. A temporary solution to get around this issue is to use Cocoapods for your Facebook SDK dependency which will help while a fix is worked on.
The bug has been acknowledged by Facebook & is being assigned to the appropriate team for fixing.
Please follow https://developers.facebook.com/bugs/383331175179417/ for the updates.
回答8:
make sure the facebook sdk framework and bolts framework (comes with fb sdk) is imported into your project.
回答9:
i got similar error ("...is not a dylib" and "Undefined symbols for architecture") because i dragged the whole parse folder ("parse-library-1.7.4-2") into my xcode project, when i should have dragged only the frameworks i needed ("Bolts.framework" and "Parse.framework"). deleted the parse folder, dragged over the two frameworks, then everything works as expected :)
回答10:
I had the exact same problem. Updating Bolts to 1.1.4 solved it for me (Bolts was 1.1.3 before).
If you use cocoapods, change or add this line to your podfile
pod 'Bolts', '1.1.4'
If not, just download it here : https://github.com/BoltsFramework/Bolts-iOS/releases

Try downloading the latest SDK and replacing all of the Parse frameworks with the latest version.
