Handling Errors in Swift:
In Swift, this method returns Void
and is marked with the throws
keyword to indicate that it throws an error in cases of failure.
You call this method in a try
expression and handle any errors in the catch
clauses of a do
statement, as described in Error Handling in The Swift Programming Language and About Imported Cocoa Error Parameters.
