Still having problems with Parse Import

I have followed along to the point where we add our Parse keys in the app delegate, and run. Unfortunately though when I go to run, I get the following errors that I don't quite understand:

Undefined symbols for architecture i386:

"OBJC_CLASS$BFExecutor", referenced from: objc-class-ref in Parse(BFTask+Private.o) l_OBJC$CATEGORY_BFExecutor$Background in Parse(BFTask+Private.o) "_OBJC_CLASS$BFTask", referenced from: objc-class-ref in Parse(PFUser.o) objc-class-ref in Parse(PFFile.o) objc-class-ref in Parse(PFNetworkCommandRunner.o) objc-class-ref in Parse(PFObject.o) objc-class-ref in Parse(PFPush.o) objc-class-ref in Parse(PFRetryingCommandRunner.o) l_OBJC$CATEGORY_BFTask$Private in Parse(BFTask+Private.o) ... "_OBJC_CLASS$_BFTaskCompletionSource", referenced from: objc-class-ref in Parse(PFCommandCache.o) objc-class-ref in Parse(PFNetworkCommandRunner.o) objc-class-ref in Parse(PFObject.o) objc-class-ref in Parse(BFTask+Private.o) objc-class-ref in Parse(PFTaskHTTPRequestOperation.o) ld: symbol(s) not found for architecture i386 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Any suggestions Ben Jakuben ?

I have included bolts framework, but do I need to explicitly reference in my implementation file? So far I have tried re-importing Parse as well as restarting Xcode.

Any help would be much appreciated, as I haven't been able to move forward with the project.

Thanks!

Sorry about your trouble with this! I added a Teacher's Note on that page, but it sounds like that is still being missed. The Parse SDK now requires another framework that is included in the zip file from Parse: Bolts.framework. Copy this into your project just like Parse.framework, and then the errors will go away. Let us know if you still have trouble after trying that.

I was able to see find the solution by searching for "Parse BFExecutor". I saw the Bolts.framework mentioned then went back to read the instructions on the new Parse Quickstart guide and saw that this is now required.

I actually have that added, and it still is giving the same errors.

Hmmm...sounds like it's not being recognized somehow. First try cleaning and rebuilding your project. Then click on the Project in the Navigator, Click the Build Phases at the top, and make sure Bolts.framework is listed in the "Link Binary With Libraries" section. You may need to add it there if it's not added for you.

That was it! Even though it was included in the project's framework directory, it needed to be added manually in the 'Link Binary With Libraries' section.

Thanks Ben Jakuben!
