Iterate through files in a folder and its subfolders using Swift's FileManager
Use the nextObject()
method of enumerator
:
while let element = enumerator?.nextObject() as? String {
if element.hasSuffix("ext") { // checks the extension
}
}
Nowadays (early 2017) it's highly recommended to use the – more versatile – URL related API
let fileManager = FileManager.default
do {
let resourceKeys : [URLResourceKey] = [.creationDateKey, .isDirectoryKey]
let documentsURL = try fileManager.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: false)
let enumerator = FileManager.default.enumerator(at: documentsURL,
includingPropertiesForKeys: resourceKeys,
options: [.skipsHiddenFiles], errorHandler: { (url, error) -> Bool in
print("directoryEnumerator error at \(url): ", error)
return true
})!
for case let fileURL as URL in enumerator {
let resourceValues = try fileURL.resourceValues(forKeys: Set(resourceKeys))
print(fileURL.path, resourceValues.creationDate!, resourceValues.isDirectory!)
}
} catch {
print(error)
}
I couldn't get pNre's solution to work at all; the while loop just never received anything. However, I did come across this solution which works for me (in Xcode 6 beta 6, so perhaps things have changed since pNre posted the above answer?):
for url in enumerator!.allObjects {
print("\((url as! NSURL).path!)")
}
