How to read the contents of a directory using FileManager
If you want to work with files FileManager almost certainly has the answer, and it's no different in this case: it has a method called contentsOfDirectory(atPath:) that lists all the files in a specific directory. For example, we could have it list all the files in our app's resource directory like this:
let fm = FileManager.default
let path = Bundle.main.resourcePath!
do {
let items = try fm.contentsOfDirectory(atPath: path)
for item in items {
print("Found \(item)")
}
} catch {
// failed to read directory – bad permissions, perhaps?
}In this particular case the try should never fail, but you should still have the catch block in there just in case.
