iOS Error Handling in Swift Error Handling Modeling and Throwing Errors

the question is "To call a throwing function we need to mark it with a certain keyword to indicate that this function?"

It says the answer to this is 'try' but that doesn't seem right to me isn't the answer 'throws'?

Hi Matthew

Nope, it's try. Note that the question is asking about calling the function. try is the keyword we use to tell the compiler that the function we are calling can return an error. throws is used in the function declaration, and throw is used to indicate exiting out of the function.

Hope that's clear

Cheers

Alex
