The method for handling errors in Swift differ a bit from Objective-C. In Swift, it's possible to declare that a function throws an error. It is, therefore, the caller's responsibility to handle the error or propagate it. This is similar to how Java handles the situation.
You simply declare that a function can throw an error by appending the throws keyword to the function name. Any function that calls such a method must call it from a try block.
func canThrowErrors() throws -> String
//How to call a method that throws an error
try canThrowErrors()
//Or specify it as an optional
let maybe = try? canThrowErrors()
