Creating and Account and App on Parse: Build failed with no explanation?


Any help will be appreciated. I am having trouble with the Creating and Account and App on Parse.com section of the self destructing app track. I have downloaded and included all the frameworks needed as Ben said to do, including the parse framework. I have followed both Ben and Parse's instructions with the code. However every time I try and run the app I see that the build has failed and am presented with 4 error messages!

"OBJC_CLASS$_BFExecutor", referenced from:

"OBJC_CLASS$_BFTask", referenced from:

"OBJC_CLASS$_BFTaskCompletionSource", referenced from:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

^^ Have just copied and pasted from Xcode. Please can someone explain why this is happening and outline what steps can be taken to rectify the problem.

Many thanks

Hi! I think this question is already answered in other post in this forum! Take a look at Parse.com as it seems now instructions added are required!

Thanks a lot Francisco, I should have looked at the Teacher Notes. Problem resolved
