Simple googling would lead me to the code:
let fileManager = FileManager.defaultManager()
// Get current directory path
let path = fileManager.currentDirectoryPath
print(path)
However, defeaultManager seems not to be accessible in Linux.
How can I find the current path using either Foundation or Glib in swift?
That code is for Swift 3. Here is the code for swift 4:
let fileManager = FileManager.default
// Get current directory path
let path = fileManager.currentDirectoryPath
print(path)

From this question: How can I get all image names in asset catalog group?
I want to access a file created in the root of an App in Swift.
My App is called Challenge and my script is
# Type a script or drag a script file from your workspace to insert its path.
#!/bin/sh
>./Challenge/fileNames.txt
for FILE in ./Challenge/Images.xcassets/actions/*; do
echo $FILE >> ./Challenge/fileNames.txt
done
I have tried
let fileManager = FileManager.default
let imagePath = Bundle.main.resourcePath! + "fileNames.txt"
let imageNames = try! fileManager.contentsOfDirectory(atPath: imagePath)
And many other combinations .
This is not homework, I have tried various solutions but as I am not sure where the file is within the file system (how the root can be accessed within the App) I seem unable to locate the file.
Question: How to read ./Challenge/fileNames.txt from an App called challenger, created by a script during the build phase.
The file is located in the main bundle folder, not resource path:
let fileManager = FileManager.default
let imagePath = Bundle.main.path(forResource: "fileName", ofType: "txt")
let content = try! String(contentsOfFile: imagePath)
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"
Note that you want to use URL wherever possible, from the NSURL documentation:
URL objects are the preferred way to refer to local files. Most
objects that read data from or write data to a file have methods that
accept an NSURL object instead of a pathname as the file reference.
Here’s an example of how to get all the objects from a directory:
import Foundation
let manager = FileManager.default
// Get URL for the current user’s Documents directory
// Use URL instead of path, it’s more flexible and preferred
if let documents = manager.urls(for: .documentDirectory, in: .userDomainMask).first,
// Get an Enumerator for the paths of all the objects in the directory
// but do not descend into directories or packages
let directoryEnumerator = manager.enumerator(at: documents, includingPropertiesForKeys: [URLResourceKey.pathKey], options: [.skipsSubdirectoryDescendants, .skipsPackageDescendants]) {
// iterate through the objects (files, directories, etc.) in the directory
for path in directoryEnumerator {
print(path)
}
}
How is it possible?
let exists = NSFileManager.defaultManager().fileExistsAtPath(path.absoluteString)
print("exists: \(exists)") //false
This is path.absoluteString
//file:///Users/kuna/Library/Developer/CoreSimulator/Devices/92BD140D-5C14-43C4-80D6-904BB9594ED6/data/Containers/Data/Application/5B818832-BB19-4047-A7F8-1487F36868D6/Documents/wishlists/68/147/128/IMG_0006.PNG
And you can see it is there where it should be:
What is going on?
(The code in this answer has been updated for Swift 3 and later.)
Apparently your path variable is a NSURL (describing a file path). To get the path as
a string, use the path property, not absoluteString:
let exists = FileManager.default.fileExists(atPath: path.path)
absoluteString returns the URL in a string format, including
the file: scheme etc.
Example:
let url = URL(fileURLWithPath: "/path/to/foo.txt")
// This is what you did:
print(url.absoluteString)
// Output: file:///path/to/foo.txt
// This is what you want:
print(url.path)
// Output: /path/to/foo.txt
If you want to check if a path exist,you should check path
let url = NSURL(string: "balabala")
let path = url?.path
//Check path
I'm writing a script in Swift, and I want it to modify some files that always exist in the same directory as the script itself. Is there a way to get the path to the script from within itself? I tried:
print(Process.arguments)
But that outputs only the path that was actually given to the script, which may be the fully resolved path, just the file name, or anything in between.
I'm intending the script to be run with swift /path/to/my/script.swift.
The accepted answer doesn't work in Swift 3. Also, this is a more straightforward approach:
import Foundation
let currentDirectoryURL = URL(fileURLWithPath: FileManager.default.currentDirectoryPath)
let url = URL(fileURLWithPath: CommandLine.arguments[1], relativeTo: currentDirectoryURL)
print("script at: " + url.path)
However, it has the same problem pointed out by #rob-napier, if the script's directory is in your PATH.
just in swift:
let cwd = FileManager.default.currentDirectoryPath
print("script run from:\n" + cwd)
let script = CommandLine.arguments[0];
print("\n\nfilepath given to script:\n" + script)
//get script working dir
if script.hasPrefix("/") { //absolute
let path = (script as NSString).deletingLastPathComponent
print("\n\nscript at:\n" + path)
} else {
let urlCwd = URL(fileURLWithPath: cwd)
if let path = URL(string: script, relativeTo: urlCwd)?.path {
let path = (path as NSString).deletingLastPathComponent
print("\n\nscript at:\n" + path)
}
}
I am new at Swift programming language. I want to download a movie from some tube servers and want to play offline. I am using Alamofire for downloading part. I can list the file(s) with that:
var file:String?
if let files = NSFileManager.defaultManager().contentsOfDirectoryAtPath(documentsDirectory, error: &error) as? [String] {
for filename in files {
// do stuff with filename
file = filename
println(filename)
}
}
But the problem is how i can use that file for my purpose. Let assume its image file and i want to show in imageview.
myImageView.image = UIImage(contentsOfFile: file) /* doesn't work*/
thank you for any help.
For Swift 2 you have to change something. Note: stringByAppendingPathComponent is not more available on String (only NSString):
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as NSString
var getImagePath = paths.stringByAppendingPathComponent("filename")
myImageView.image = UIImage(contentsOfFile: getImagePath)
Try this code:
var paths = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0] as String
var getImagePath = paths.stringByAppendingPathComponent("filename")
myImageView.image = UIImage(contentsOfFile: getImagePath)
I hope this work.
File manage is used for below functionality, Please check once.
1) create folder in document directory or temp directory,
2) copy file from temp to document directory, move path,
3) remove from document directory,
4) list all file from document directory, list file using extension from document directory (ex: if you have .mp3 and .jpg and .text files in document directory and you want only .mp3 file),
5) save file
6) get file path

At the moment you're just passing in the name of the file to UIImage(contentsOfFile). You need to pass in the entire path, i.e.:
myImageView.image = UIImage(contentsOfFile: "\(documentsDirectory!)/\(filename)") //hopefully does work!
