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

Question

I'm new to Swift and I have a little problem.

I have a piece of code, and any line could potentially throw an error.

My problem is, I don't want to go through line by line catching each error, I want to catch them all in one statement.

In python you can do this

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

What that does is try to print a value from the array that doesn't exist, but it is caught by the except statement, I am wondering whether something this easy exists in Swift

To clarify, I am not trying to catch an index out of range error, I just want to catch an error, no matter what it is.

Is it possible without declaring my own errors, and throwing them line by line?

Answer 1

In Swift you can only catch errors that are thrown.

Since not all errors are handled by throwing (e.g. an out-of-range array access), you cannot catch everything.
