Swift - Day 3 : Exception handling

Though there’s nothing exceptionally new to me about how Swift deals with exceptions, I do have to say that I prefer it’s way of dealing with functions that throw an error. I find them to be easier to read compared to languages like java.

Suppose we have a function canThrow() which may throw as shown below.

    func canThrow() throws {
    	//Some logic that may result in an error

What I like about Swift is the way the function is called in a different part of the code that handles/catches the error.

    do {
    	try canThrow()
    } catch SomeError.happened {

By having try before the function that could potentially throw an error,it is clear to anyone reading the code where an exception may come from.
