Using NSFileManager and createDirectoryAtPath in Swift

Question

I\'m trying to create a new folder, but I can\'t figure out how to use createDirectoryAtPath correctly.

According to the documentation, this is the correct syntax:

Answer 1

Based on seb's code above. When I used this in my function I had to add a generic catch too. This removed the "Errors thrown from here are not handled because the enclosing catch is not exhaustive" error.

do {
    var deliverablePathString = "/tmp/asdf"
    try NSFileManager.defaultManager().createDirectoryAtPath(deliverablePathString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    NSLog("\(error.localizedDescription)")
} catch {
    print("general error - \(error)", appendNewline: true)
}

Answer 2

The Swift 2.0 way:

do {
    var deliverablePathString = "/tmp/asdf"
    try NSFileManager.defaultManager().createDirectoryAtPath(deliverablePathString, withIntermediateDirectories: false, attributes: nil)
} catch let error as NSError {
    NSLog("\(error.localizedDescription)")
}

Answer 3

createDirectoryAtPath expects a String for the first parameter, not a URL. Try passing your path directly or use the URL-friendly variant createDirectoryForURL.

Here is an example:

NSFileManager.defaultManager().createDirectoryAtPath("/tmp/fnord", withIntermediateDirectories: false, attributes: nil, error: nil)

Answer 4

You forgot to add defaultManager() and to convert the NSURL to String.

You can try replacing

NSFileManager.createDirectoryAtPath(deliverablePath, withIntermediateDirectories: false, attributes: nil, error: nil)

with this (converting your NSURL to String)

var deliverablePathString = deliverablePath.absoluteString

NSFileManager.defaultManager().createDirectoryAtPath(deliverablePathString, withIntermediateDirectories: false, attributes: nil, error: nil)

Hope this helps
