Creating Folder in Application Support if not Exists

Question

I'm trying to create a folder in Application Support Directory.

let path = FileManager.default.urls(for: .applicationSupportDirectory, in: .userDomainMask)[0]
let fileurl =  path.appendingPathComponent("my folder")
do {
try FileManager.default.createDirectory(atPath:String(describing: fileurl), withIntermediateDirectories: true, attributes: nil)
} catch {
 print(error)
}

But no folder is created.What I'm I doing wrong?

My comment https://stackoverflow.com/questions/46695044/decrypted-string-always-returning-null#comment80338247_46695044 to your previous question applies here as well: Never use `String(describing:)` ! — Martin R, Oct 12 '17 at 13:09

The error occurs because you are passing the string representation of an URL which includes the file:// scheme but createDirectory(atPath expects a path without the file:// scheme.

The solution is so easy: (Always) use the URL related API of FileManager

try FileManager.default.createDirectory(at: fileurl, withIntermediateDirectories: true)

Please consider a more meaningful variable naming

path is actually url
fileurl is actually folderurl

Thanks ... Does this method check if the Directory already exists ? – techno Oct 12 '17 at 17:41
No, you have to check this. – vadian Oct 12 '17 at 21:19
@techno No need to check if exists. It will only create the directory if it doesn't exist. – Leo Dabus Oct 13 '17 at 03:24
