[SOLVED] Error: duplicate symbol _BFTaskMultipleExceptionsException

Error: duplicate symbol _BFTaskMultipleExceptionsException

Here I have an error as shown below:

This seems to be duplicate symbols caused by FacebookSDK and Bolts conflicting each other on build. I have tried to remove Bolts framework but it caused other issues. Also I found this question but it seems to settle with adding those frameworks as Pods which I don't want to.

Here below is a list of frameworks that I think it might be relevant to this error:

FacebookSDK.framework
Bolts.framework
Parse.framework
ParseFacebookUtils.framework
ParseFacebookUtilsV4.framework
ParseUI.framework

I've been trying to look for a right combination of those frameworks(versions) that won't cause duplication symbols error. If anyone know about this, please help me out.

Solution

Thanks to a comment from @vadian that brought me to look into my PAWAppDelegate.m and I found that after I comment out this line:

NSString *const BFTaskMultipleExceptionsException = @"BFMultipleExceptionsException";

the error disappears.
