Swift Question

How can I tell if a string is an URL or a local path?

I'm given a string. It will either be a local path to a file that exists or a fully qualified remote https url ending in a file component.

If it is a local path I want to use

NSURL(fileURLWithPath: String)

If it is an URL, I want to use
NSURL(string: String)

What is the simplest / most reliable way to decide which to use?

Answer Source

A local file path string will always start with / assuming it is a full path (which it should be).

A remote https URL will start with https://

Simply check which prefix the string has.
