I recorded the users voice with an AVAudioRecorder and saved it as a .m4a file in the documents folder. When I am trying to load the .m4a file into an NSDataobject, the object is nil.
The .m4a file contains sound and the used file path is correct.
I am using the following line to load the .m4a file:
let soundData = NSFileManager.defaultManager().contentsAtPath(soundPath)
println("\(soundData)") // prints nil
It appears that the AVAudioPlayer requires a path with a "file://" prefix, while SFileManager.defaultManager().contentsAtPath() needs this prefix removed from the path in order to work properly. Try removing this by doing something like:
soundPath = soundPath.stringByReplacingOccurrencesOfString("file://", withString: "", options: NSStringCompareOptions.LiteralSearch, range: nil)
From the docs: "If path specifies a directory, or if some other error occurs, this method returns nil."
The The best way to check for the file is in Xcode: Menu Windows:Devices. Select the device connected to the computer, double click the app, Examine the file contents.
println("sound path: (soundPath)"), bets are it is not correct.
Consider using the NSData method, it has an error parameter to better report a failure:
+ (id)dataWithContentsOfFile:(NSString *)path options:(NSDataReadingOptions)mask error:(NSError **)errorPtr
Example with error reporting:
let error:NSError
let soundData = NSData().contentsOfFile: soundPath options: 0 error: &errorPtr)
if soundData != nil {
// Do something
}
else {
println("error: \(error!.localizedDescription)")
}
Example error message:
error: The file “TestSound.m4a” couldn’t be opened because there is no
such file.
BTW, a more clear name for the path: sound might be soundPath.
Release the AVAudioRecorder before trying to load the url to NSData.

I have a few items that are saved to the documents directory. I currently need those to be moved programmatically to another directory. I created the new directory successfully, but it doesn't seem to be looking at that when using FileManager.default.moveItem.
Code used to created directory.
let path = getDocumentsDirectory().appendingPathComponent("Media").path
do{
try FileManager.default.createDirectory(atPath: path, withIntermediateDirectories: false, attributes: nil)
print("\nDIRECTORY 'Media' CREATED")
}catch {
print("\nDIRECTORY 'Media' WAS NOT ABLE TO BE CREATED")
print("ERROR - \(error)")
}
I use this code to check my URL.
let mediaURL = getDocumentsDirectory().appendingPathComponent("Media")
print("\nMEDIA URL: \(mediaURL)")
Which outputs this.
MEDIA URL:file:///Users/joseph/Library/Developer/CoreSimulator/Devices/552B72BF-8929-40EE-A75B-4574D3D2918A/data/Containers/Data/Application/E168B872-6A1D-4D78-B460-D45194088E5B/Documents/Media/
Here is the code I'm using to move the items.
do{
try FileManager.default.moveItem(at: url, to: mediaURL)
print("\nFILE MOVED TO NEW MEDIA PATH SUCCESSFULLY")
}catch {
print("\nCOULDN'T MOVE FILE TO NEW MEDIA PATH")
print("ERROR - \(error)")
}
Here is the error I'm receiving for each item that I try to move.
COULDN'T MOVE FILE TO NEW MEDIA PATH
ERROR - Error Domain=NSCocoaErrorDomain Code=516 "“image_5” couldn’t be moved to “Documents” because an item with the same name already exists."

The media directory should be empty, as it is newly created, so the error I'm receiving is a bit confusing. It's also saying it's trying to move it to 'Documents', but it should be moving to 'Media'.What is causing this issue, and how can I resolve it? I'm just trying to move the items saved in 'Documents' to the new directory, 'Media'.
You must append the file name to the destination URL. Per the docs:
The new location for the item in srcURL. The URL in this parameter must not be a file reference URL and must include the name of the file or directory in its new location. This parameter must not be nil.
Delete the old file if exist
let url = NSUrl(string: "...")
if NSFileManager.defaultManager().fileExistsAtPath(url.path!) {
try! NSFileManager.defaultManager().removeItemAtURL(url)
}
Update:
Swift 5.1.2
let url = URL(string: mp3FilePath)
if FileManager.default.fileExists(atPath: url!.path) {
try! FileManager.default.removeItem(at: url!)
}
This worked for me - Add the name of file too in destination path
let nameFile = (songPath as NSString).lastPathComponent
let fileDest = destinationDirectoryPath + "/" + nameFile
//Now move the song files
try fileManager.moveItem(atPath: sourceFilePath, toPath: fileDest)
So the app I'm making creates a file called "logfile" and I'm trying to send that file via Alamofire upload to a server. The file path printed in the console log is
/var/mobile/Containers/Data/Application/3BE13D78-3BF0-4880-A79A-27B488ED9EFE/Documents/logfile.txt
and the file path I can use to manually access the log created in the .xcappdata is
/AppData/Documents/logfile.txt
To access it, I'm using
let fileURL = Bundle.main.url(forResource: "", withExtension: "txt")
where inbetween the double quotes for "forResource", I've tried both file paths I listed in the previous paragraph as well as just the file name but I'm getting a nil value for file found for either. The file isn't recognized to be there, presumably because the file path I'm using is wrong as Alamofire is returning nil when trying to locate send the file. Anyone know the direct file path I'm supposed to use to be able to grab my file since the other two don't supposedly work? Thank you!
Use below code to get string data from text file to upload to server:
let fileName = "logfile"
let documentDirURL = try? FileManager.default.url(for: .documentDirectory, in: .userDomainMask, appropriateFor: nil, create: true)
let fileURL = documentDirURL.appendingPathComponent(fileName).appendingPathExtension("txt")
print("FilePath: \(fileURL.path)")
var readString = "" // Used to store the file contents
do {
// Read the file contents
readString = try String(contentsOf: fileURL)
} catch let error as NSError {
print("Failed reading from URL: \(fileURL), Error: " + error.localizedDescription)
}
print("File Text: \(readString)") // Send 'readString' to server
If you're dynamically creating the file at runtime, it won't be in your app bundle so the Bundle class won't be able to find it. The directories you see are also dynamically-generated and not only platform-specific, but also device-specific, so you can't use the file paths directly. Instead, you'll have to ask for the proper directory at runtime from the FileManager class, like this:
guard let documents = FileManager.default.urls(for: .documentsDirectory, in: .userDomainMask).first else{
// This case will likely never happen, but forcing anything in Swift is bad
return
}
let logURL = URL(string: "logfile.txt", relativeTo: documents)
do{
let fileContents = String(contentsOf: logURL)
// Send your file to your sever here
catch{
// Handle any errors you might've encountered
}
Note that I'm guessing based on the paths you pasted in your answer you put it in your application's documents directory. That's a perfectly fine place to put this type of thing, but if I'm wrong and you put it in a different place, you'll have to modify this code to point to the right place
my problem is when i try to copy images from the photo library to the filesystem i get the error the error is

let document = fileManager[0]
var i = 0
for asset in arrayOfAssets {
let filePath = document.appendingPathComponent("image\(arrayOfAssets.count + i).png")
i += 1
PHImageManager.default().requestImageData(for: asset, options: nil) { (data, nil, _ , info) in
let url = info?["PHImageFileURLKey"] as! NSURL
do {
try FileManager.default.copyItem(at: url as URL, to: filePath)
}catch {
print(error)
}
// print(filePath)
}
}
please if anyone can help me
thanks all
It sounds like you're trying to open a file located here : NSFilePath=/var/mobile/Media/DCIM/100APPLE/IMG_0926.JPG
By default access to this directory is not permitted, you can only access files located in the document directory, for security reasons.
I don't find where this URL comes from in your code, but according to the NSError you are trying to access an image outside the permitted area of the file system.
Please check the permission option in plist for Photos Library in iOS 11.
Also you can save data in TEMP directory and fetch it when needed and after use
clean data in TEMP directory.
Using LXLogger I am able to write log entries to file on the device and simulator (in addition to xcode console etc).
The default location which LXLogger stores the file is under the ApplicationSupportDirectory.
LXLogger writes to the file OK, and I can see the file is on my device (or on my mac HDD when using the simulator), but when I try to open the file I am told that the file does not exist.
I have added the error logs generated in line with the code.
I've tried a dozen different methods and multiple questions on here, to no avail.
let directory = NSFileManager.defaultManager().URLsForDirectory(.ApplicationSupportDirectory, inDomains: .UserDomainMask).first!.URLByAppendingPathComponent(NSBundle.mainBundle().bundleIdentifier!, isDirectory: true).URLByAppendingPathComponent("logs", isDirectory: true)
do {
let array = try NSFileManager.defaultManager().contentsOfDirectoryAtURL(directory, includingPropertiesForKeys: nil, options:[])
var str = array[0].description
str = str.stringByReplacingOccurrencesOfString("file://", withString: "", options: .LiteralSearch, range: nil)
let fileURL = NSURL(fileURLWithPath:str)
log.info("fileURL contains: " + fileURL.absoluteString)
do {
log.info("Attempting to get contentsOfURL")
let data = try NSString(contentsOfFile: array[0].description,
encoding: NSASCIIStringEncoding)
logTextView.text = data as String
} catch let error as NSError {
log.error(error.description)
}
}
catch let error as NSError {
log.error(error.description)
}
Log Outputs from above code:

So the code shows that the file is there (and i can physically open the copy on my mac), but the app can't find it.
Presumably its something to do with my usage of the file handle/nsurl/something like that??
Your approach of taking the NSURL from array and using stringByReplacingOccurrencesOfString and fileURLWithPath and then description is wrong; it doesn't correctly handle the percent-encoding in the URL and it's generally complex/fragile.
This can be much simpler, because you already have a file URL returned in the array from contentsOfDirectoryAtURL. You can just use it directly:
let data = try String(contentsOfURL: array[0], encoding: NSUTF8StringEncoding)
I'm trying to move my files up a level in some random directory in the default Documents directory. But when copying, Swift gave me the error Cocoa Error 262: NSFileReadUnsupportedSchemeError. Why did I get this error? I ran a quick search and pretty much everyone who'd encountered this problem was trying to copy files out of the camera roll, but I'm not. Any thoughts? Thanks in advance.
Code here:
private func copyFilesInDirectory(fromDir: String, toDirectory toDir: String, withCompletionHandler handler: ()->()){
println("from: \(fromDir)\nto: \(toDir)")
var error: NSError?
var contents = fileManager.contentsOfDirectoryAtPath(fromDir, error: &error)
if let dirContents = contents{
let enumerator = (dirContents as NSArray).objectEnumerator()
while let file = enumerator.nextObject() as? String{
let filePath = fromDir.stringByAppendingString("/\(file)")
println("copying \(filePath)")
if(fileManager.copyItemAtURL(NSURL(fileURLWithPath: filePath)!, toURL: NSURL(string: toDir)!, error: &error)){
println("COPIED")
}
else{
println("COPY ERROR: \(error!.localizedDescription)")
}
}
handler()
}
}
and here's the log if anyone's interested:

COPY ERROR: The operation couldn’t be completed. (Cocoa error 262.)
The toURL parameter of copyItemAtURL() must not be the destination
directory, but the URL of the destination file. This can be
created with
let destPath = toDir.stringByAppendingPathComponent(file)
You should also replace
let filePath = fromDir.stringByAppendingString("/\(file)")
with
let filePath = fromDir.stringByAppendingPathComponent(file)
There is also a copyItemAtPath() method which saves you from
converting the paths to URLs.
On an iOS device, the simple answer is you can't do that. On the simulator things are little different. What you're probably dealing with is file permissions on the directory you're trying to write to.
As a general rule on iOS, you can write to the designated directories like the documents/caches and nothing else.
