I'm looking over the NSFileManager.h
dox in Swift 4 and it seems it changed since I last used it (for the better!).
I'm wondering if contentsOfDirectoryAtURL:includingPropertiesForKeys
, url
or enumeratorAtURL:includingPropertiesForKeys
provides a way to enumerate over a specific type of file, in my case images?
I've looked at the many Swift 2 answers and they all suggest looping and examining the name, and I want to be sure they haven't "fixed" this and I'm simply confused by the API?
Just filter
the returned URLs
by pathExtension
do {
let docs = try FileManager.default.contentsOfDirectory(at: .documentsDirectory, includingPropertiesForKeys: nil, options: .skipsHiddenFiles)
let images = docs.filter{ $0.pathExtension == "xxx" }
print(images)
} catch {
print(error)
}
