When using
let directoryEnumerator = FileManager().enumerator(at: ...
in Swift 3, I get all files from the folder, e.g.
"file:///Volumes/MacOS/fasttemp/Fotos/"
The results are not including the leading path (here "/Volumes/MacOS"). So I get
"file:///fasttemp/Fotos/2005/"
How can I get the fullpath (directly from the enumerator) or convert them. I want to use URL functions, not string function manipulating by assumptions.
If "MacOS" is the name of your current startup disk then "/Volumes/MacOS" is a symbolic link to "/", so both "/fasttemp/Fotos/2005/" and "/Volumes/MacOS/fasttemp/Fotos/" are absolute paths to the same file.
In order to get a unique file name representation you can query a URL for its canonical path. Example:
let url = URL(fileURLWithPath: "/Volumes/MacOS/Applications/Utilities/")
if let cp = (try? url.resourceValues(forKeys: [.canonicalPathKey]))?.canonicalPath {
print(cp)
}
// Output: "/Applications/Utilities"
This requires macOS 10.12/iOS 10 or later. On older systems you can
use the realpath()
system call:
if let rp = url.withUnsafeFileSystemRepresentation ({ realpath($0, nil) }) {
let fullUrl = URL(fileURLWithFileSystemRepresentation: rp, isDirectory: true, relativeTo: nil)
free(rp)
print(fullUrl.path)
}
// Output: "/Applications/Utilities"
