AWSCore uses Bolts framework as the main promise engine, as you can see here https://github.com/aws/aws-sdk-ios/blob/master/AWSCore/Bolts/AWSBolts.h.

If you want a refresh about the BSD + Patents, look here
This is obviously only a fraction of the whole SDK, but it is widely used across different classes.
Look for example the
- (AWSTask<AWSAPIGatewayResponse *> *)invoke:(AWSAPIGatewayRequest *)apiRequest;
Every time you call the APIGateway function it returns an AWSTask. That task code is licensed under the BSD + Patents. So every time you communicate with Amazon servers using that function, you are accepting the license.
I doubt amazon will rewrite their SDK only for this issue, It's more likely that Bolts update its license, I hope so :).
I’ve sent a message to my family and delegated my open source projects to my friends. With my last tweet sent, I turn off my laptop, phone, and tablet. My Digital Sabbath begins in 10 minutes: no digital devices for the next month.
