In Swift, you can find the file extension of a file by using the pathExtension
property of the URL
class. Here's an example:
main.swift128 chars4 lines
In the code above, we create a URL
object with the path to our file. We then access the pathExtension
property of the URL
object to get the file extension.
Note that the pathExtension
property only returns the extension of the file name, not including the period (.
) separator. If you need to include the period separator, you can manually append it to the extension string:
main.swift99 chars3 lines
