<스위프트> try catch

do try catch로 구성하면 되는 거였다.

 

do – This keyword starts the block of code that contains the method that can potentially throw an error.

 

try – You must use this keyword in front of the method that throws. Think of it like this: “You’re trying to execute the method.

 

catch – If the throwing method fails and raises an error, the execution will fall into this catch block. This is where you’ll write code display a graceful error message to the user.

 

Use this pattern to handle any potential errors caused by a method that throws.
