I am using SwiftyDropbox API to upload images to dropbox. I have image in project directory and trying to upload it like this :
// Verify user is logged into Dropbox
if let client = Dropbox.authorizedClient {
let imagePath : NSString = NSBundle.mainBundle().pathForResource("abc", ofType: "png")!
print("Path :--> \n", imagePath)
let url : NSURL = NSURL(string: imagePath as String)!
client.files.upload(path: "", body: url).response{response, error in
if let metadata = response {
print("*** Upload file ****")
print("Uploaded file name: \(metadata.name)")
self.delegate?.imageSavedSuccessfully()
}
else{
print(error!)
}
}
And the error I get is (including screenshot too.):
precondition failed: " must match pattern "\A(?:/.*)\z":
Any hint or guide what I am doing wrong? Thank you in advance.
For your file upload, you're specifying the path "", but that represents the root folder, not a file path.
Instead, the path should be the full path where you want to upload the file, including the file name. For example, to upload the file as "abc.png" in the root of the Dropbox account, you'd specify the path as "/abc.png".

Okay, so basically I'm creating a messenger app which I want to be able to upload and load a profile picture. Currently I can successfully upload a picture to firebase, but as stated in the title, it fails to download the picture URL.
(Tutorial that I am watching: https://www.youtube.com/watch?v=Hmr8PsG9E2w&list=PL5PR3UyfTWvdlk-Qi-dPtJmjTj-2YIMMf&index=18&ab_channel=iOSAcademy) 15-20 min into the video.
Where the error occurs:
strongSelf.storage.child("images/"+fileName).downloadURL(completion: {url, error in
guard let url = url else {
print("Failed to get download url")
completion(.failure(StorageErrors.failedToGetDownloadUrl))
return
}
let safeEmail = DatabaseManager.safeEmail(emailAddress: email)
let filename = safeEmail + "_profile_picture.png"
let path = "images/"+filename
Error message in console
What I've tried:
Changing and double checking that the path leads to the picture.
Trying different tactics of calling path like ("(path)") instead of (path)
Other random stuff that I found looking for this problem on the web
What my conclusion so far is that the program does not seem to indentify the correct path to the picture, but I've made sure that it looks identical to the video.
Would be awesome if anyone knows or has any idea how to deal with this issue? This is my first post so please tell me if more information is needed regarding the code is needed.
Cheers // Jakob
Adding extra to comments:
So the (error) is : failedToGetDownloadUrl
So this is where I suspect there is something going wrong:
strongSelf.storage.child("images/\(fileName)").downloadURL(completion: { url, error in
guard let url = url else {
print("Failed to get download url")
completion(.failure(StorageErrors.failedToGetDownloadUrl))
return
}
let urlString = url.absoluteString
print("download url returned: \(urlString)")
completion(.success(urlString))
})
})
}
And here are the Path to the images:
let safeEmail = DatabaseManager.safeEmail(emailAddress: email)
let filename = safeEmail + "_profile_picture.png"
let path = "images"+filename
And this is my firebase storage:
I have a problem accessing my files.
I am trying to create a file and send it over FTP. However, when I tried to read the file I created, I got this error message. Can you check where did I made a mistake?
The FTP upload was from https://gist.github.com/Nirma/fb9991be776107d17fdcd6ed2aa02876
The TXT file was created successfully with following codes, I can view it on my iPad simulator.
// Create TXTFile
let fileName = "test.txt"
self.save(text: "some text shown here", toDirectory: self.documentDirectory(), withFileName: fileName)
self.read(fromDocumentsWithFileName: fileName)
But the error happens when I execute the FTPupload codes.
// FTP upload
let ftp = FTPUpload(baseUrl: "XXX.XXX.XXX.XXX", userName: "XXXXXXX", password: "XXXXXXX", directoryPath: "XXXXX")
let url = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
do {
***let data = try Data(contentsOf: url as URL, options: [ .alwaysMapped, .uncached])***
ftp.send(data: data , with: "test.txt") { (success) in
print("success")
}
print(data)
}
catch {
print(error)
}
}
I have tracked down that the line with stars creates the error which shows I don't have the permission to view the file.
Can anyone help me? Thanks!
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
I am trying to download a plist file from a remote location and use it in the iOS app I am creating. The file is going to be used for calendar details within the app's calendar. The goal is obviously that I can update the remote file instead of having to push updates to the app itself every time we need to make changes to calendar details.
I started with the code used in this example: Download File From A Remote URL
Here is my modified version:
// Create destination URL
let documentsUrl:URL = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first as URL!
let destinationFileUrl = documentsUrl.appendingPathComponent("2017.plist")
//let destinationFileUrl = URL(string: Bundle.main.path(forResource: String(currentYear), ofType: "plist")!)
//Create URL to the source file you want to download
let fileURL = URL(string: "https://drive.google.com/open?id=0BwHDQFwaL9DuLThNYWwtQ1VXblk")
let sessionConfig = URLSessionConfiguration.default
let session = URLSession(configuration: sessionConfig)
let request = URLRequest(url:fileURL!)
let task = session.downloadTask(with: request) { (tempLocalUrl, response, error) in
if let tempLocalUrl = tempLocalUrl, error == nil {
// Success
if let statusCode = (response as? HTTPURLResponse)?.statusCode {
print("Successfully downloaded. Status code: \(statusCode)")
}
do {
try FileManager.default.removeItem(at: destinationFileUrl)
try FileManager.default.moveItem(at: tempLocalUrl, to: destinationFileUrl)
print("File was replaced")
print(NSArray(contentsOf: tempLocalUrl))
//print(tempLocalUrl)
} catch (let writeError) {
print("Error creating a file \(String(describing: destinationFileUrl)) : \(writeError)")
}
} else {
print("Error took place while downloading a file. Error description: %#", error?.localizedDescription as Any);
}
}
task.resume()
I originally tried to overwrite the file that is bundled with the app to being with, that resulted in errors. So I instead tried to just save it in the app's documents folder and that removed that error. I had to make sure and remove any previous version of the file because it was giving me a file already exists error after the first run.
While it says everything is working (The outputs for both successful download and replaced file happen) when I print the contents of the array from the downloaded URL it just gives me nil.
This is my first attempt to use any kind of external resources in an app. Before I have always kept everything internal, so I am sure there is something glaringly obvious I am missing.
Update 1:
I realized I didn't have the correct URL to use to download a file from a Google drive. That line of code has been changed to:
let fileURL = URL(string: "https://drive.google.com/uc?export=download&id=0BwHDQFwaL9DuLThNYWwtQ1VXblk")
So now I actually am downloading the plist like I originally thought I was. Even removing the deletion issue mentioned in the first comment, I still can't get the downloaded file to actually replace the existing one.
Update 2:
I have reduced the actual file manipulation down to the following:
do {
try FileManager.default.replaceItemAt(destinationFileUrl, withItemAt: tempLocalUrl)
print("File was replaced")
print(NSArray(contentsOf: destinationFileUrl))
} catch (let writeError) {
print("Error creating a file \(String(describing: destinationFileUrl)) : \(writeError)")
}
} else {
print("Error took place while downloading a file. Error description: %#", error?.localizedDescription as Any);
}
After the replacement is performed the output of the file shows the correct new contents that were downloaded from the internet.
Later in the code when I try and access the file it seems to be nil in content again.
Look at your download completion code. You:
Delete the file at the destination URL (in case there was one
leftover)
MOVE the temp file to the destination URL (removing it from the temp
URL)
Try to load the file from the temp URL.
What's wrong with this picture?
You are trying to get the contents of the moved file. You already moved the file to destination url and then you are trying to get the contents of the file from temporary location.
For getting file data, Please try the following :
let fileData = try! String(contentsOf: destinationFileUrl, encoding: String.Encoding.utf8)
print(fileData)
my problem is when i try to copy images from the photo library to the filesystem i get the error the error is
(Error Domain=NSCocoaErrorDomain Code=257 "The file “IMG_0926.JPG”

my code is :
let fileManager = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
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.
