Answer 1

You are probably linking your project to the same library or framework more than 1 time. Try to run clean in Xcode on your project, and then rebuild, and also, you should post the symbols and error codes you are receiving.

Answer 2

It is the problem of PayPal SDK. The library you are using was built with XCode 6.3. And if you are trying to build using lower version than that that is the reason behind the duplications.

In this case:

1. You can update your XCode to version 6.3
2. Try to use PayPal SDK version 2.9.0 for now.

You can see this link.

And for downloading the lower version PayPal SDK see this link.
