How to find the path to a file in your bundle
Swift version: 5.1
It’s common to store resource data like text files and sound effects inside your bundle, but loading them must be done in a particular way to avoid problems.
Rather than try to figure out the layout of your bundle at runtime, the correct thing to do is call the path(forResource:) method if you’re looking for a string path, or url(forResource:) if you’re looking for a URL.
For example, these two lines find the path to input.txt inside the bundle, as both a string and a URL:
let stringPath = Bundle.main.path(forResource: "input", ofType: "txt")
let urlPath = Bundle.main.url(forResource: "input", withExtension: "txt")Obviously you only need one of those – if you get to choose then it’s safer to go with the URL.
