Duplicate symbols between Facebook SDK and AWS v2

Question

I am getting crazy of these errors. It's been hours I am fighting it with no luck. How can I solve this thing?

I have -all_load linker flag. Tried changing to -force_load and got "ld: file not found: -fobjc-arc".

Please help.

Answer 1

First, you should make sure you are using the latest versions of the Facebook and AWS SDK. Both of them have Bolts.framework. You should include the one in the Facebook SDK, and do not import the one in the AWS SDK. Please note that when you remove a framework, you should double check Framework Search Paths doesn't point to the framework you've just removed.
