Catch all errors, exceptions, no matter what it is, in Swift

Question

I am new to Swift and I have a little problem.

I have a piece of code, and any line can potentially cause an error.

My problem is that I do not want to go line by line, catching every error, I want to catch them all in one expression.

In python you can do it

try: exampleArray = [1,2,3,4] print(exampleArray[4]) except Exception as e: print(e) pass 

What this means is an attempt to print a value from an array that does not exist, but it falls into the except statement, I wonder if something like this is possible in Swift

To clarify, I'm not trying to catch the index out of range error, I just want to catch the error, regardless of what it is.

Is this possible without announcing my own mistakes and throwing them line by line?

Answer 1

In Swift, you can only catch errors that throw n.

Since not all errors are handled with throw ing (for example, accessing an array out of range), you cannot catch everything.
