Why Swift functions don't specify the type of errors they throw?

After watching the videos on Swift Error Handling, I'm wondering why Swift functions don't specify the type of errors they throw? Instead, we need to figure out what different kinds of errors can occur in the trying functions using different catching statements.

Wouldn't it be better just to specify the type of error in the function declaration, similar to what Java and other languages do?
