I have a file that exists within the AppGroup Shared Container and I was wondering if it was possible to copy the file from the Shared Container into the application bundle.
I am getting the file path as follows :
let filePath = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("group.com.sharedBasemap")!.URLByAppendingPathComponent("localLayer.tpk")!.path
The reason I am trying to do this is it seems that the ArcGIS SDK will not recognize the TPK file from within the App Group so I am wondering if it will recognize it if I copy it into the app bundle.
EDIT: Based on Leo's comment it appears that you can not copy to the bundle, so I am trying to copy to the App Support folder.Here is my code now, I see the "file exists" message but then it is displaying the Oops message indicating it can not move the file :
let filePath = NSFileManager.defaultManager().containerURLForSecurityApplicationGroupIdentifier("group.com.sharedBasemap")!.URLByAppendingPathComponent("localLayer.tpk")!.path!
let appSupportFolder = String(NSFileManager.defaultManager().URLsForDirectory(.ApplicationSupportDirectory, inDomains: .UserDomainMask)[0]) + "localLayer.tpk"
let fileManager = NSFileManager.defaultManager()
if NSFileManager.defaultManager().fileExistsAtPath(filePath){
print("File exists at \(filePath)")
do {
try fileManager.copyItemAtPath(filePath, toPath: appSupportFolder)
}
catch let error as NSError {
print("Ooops! Something went wrong: \(error)")
}
} else {
print("File does not exist")
}
EDIT 2: I have modified the code again to just move the TPK file into the documents directory.I believe that piece is working but I receive an error message when trying to load the TPK file into ArcGIS.At this point in time, I am thinking that the issue is related to the ArcGIS SDK and that it does not support loading a TPK file from anywhere except the application bundle.
let destPath = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true).first!
let fullDestPath = NSURL(fileURLWithPath: destPath).URLByAppendingPathComponent("localLayer.tpk")
let fullDestPathString = fullDestPath!.path!
im pretty sure the appSupportFolder doesn't exist by default -- nobody creates it unless needed -- try to verify that first and create it if needed
pseudocode if(!fileExists(supportFolder)) { createDirectory(supportFolder) }

When I try to upload files via my Vapor server, it always uploads files into the DerivedData folder instead of the Public folder inside the project structure.
I can verify that the file is created in the path, but the path is somewhere in DerivedData directory .. why? How am I going to server such file when it's not in the project's Public folder?
My upload code:
func create(request: Request) async throws -> HTTPStatus {
try CreateDogRequest.validate(content: request)
let createDogRequest = try request.content.decode(CreateDogRequest.self)
guard let userId = try request.auth.require(User.self).id else {
throw Abort(.notFound)
}
let dogId = UUID()
let directory = DirectoryConfiguration.detect()
let publicFolder = "Public"
let folderPath = URL(fileURLWithPath: directory.workingDirectory)
.appendingPathComponent(publicFolder, isDirectory: true)
.appendingPathComponent("dogProfiles", isDirectory: true)
.appendingPathComponent(userId.uuidString, isDirectory: true)
.appendingPathComponent(dogId.uuidString, isDirectory: true)
print("Starting writing to path: \(folderPath)")
let filePath = folderPath.appendingPathComponent("hello" + ".jpg", isDirectory: false)
try FileManager.default.createDirectory(at: folderPath, withIntermediateDirectories: true)
let data = Data(buffer: createDogRequest.dogImage.data)
try data.write(to: filePath, options: .atomic)
print("file uploaded at: \(filePath.relativePath)")
return .ok
}
Now this shows that the file is uploaded here:
/Users/<USERNAME>/Library/Developer/Xcode/DerivedData/<PROJECT_HANDLE>/Build/Products/Debug/Public/dogProfiles/62C340CE-262B-4DE4-9E2A-99B3B3126BB6/hello.jpg
Why? How can I serve such file then?
I debugged the DirectoryConfiguration class and the detect() method checks if the server is running via Xcode and it looks like this:
#if Xcode
if workingDirectory.contains("DerivedData") {
Logger(label: "codes.vapor.directory-config")
.warning("No custom working directory set for this scheme, using \(workingDirectory)")
}
#endif
But the funny thing is, if I put a file inside the Resource folder to read data from, and use the DirectoryConfiguration's detect() method and create a path to that file, it finds the file no problem ??!!! Why? How? :D That is a mystery to me
This is the code that I wrote for reading from the file:
let directory = DirectoryConfiguration.detect()
let configDir = "Resources"
let path = URL(fileURLWithPath: directory.workingDirectory)
.appendingPathComponent(configDir, isDirectory: true)
.appendingPathComponent("file.txt", isDirectory: false)
.relativePath
What am I missing here? How come the file put inside Resources folder gets read, but when I want to put something inside the Public folder it gets put inside DerivedData even tho I am using the same patter when creating the path ??
You need to set a custom working directory in Xcode so Vapor knows where to looks. See https://docs.vapor.codes/getting-started/xcode/#custom-working-directory
Ooookay, once again, I tried to think differently and I googled a bit and found this post:
How to get path of root directory of your project folder in Perfect 2.0?
and the answer from worthbak pointed to the conclusion that I should rather run the server from terminal using swift run and try if the file gets created, and guess what? It does!
This also explains how the file I put in the Resources folder was read, because it is inside a migration that you run from guess where? .. the Terminal :)
My ultimate question is about saving a screenshot from an AppleTV application using XCTest and Swift4 (running on a MacBook paired to the TV device), but I'm having trouble even writing a simple text string to a local file. If I can get this simple file-save working, I'm hoping I can resolve the screenshot issue. (Apologies for making this look like two questions but they appear to be related and resulted from my troubleshooting efforts.)
First, here's what I'm trying to do with a screenshot, based on sample code I found somewhere online:
let appshot = XCUIApplication().windows.firstMatch.screenshot()
let shotpath = FileManager.default.urls(for: .downloadsDirectory, in: .userDomainMask)[0].appendingPathComponent("appshot.png")
let shotpathUrl = URL(string: "file://\(shotpath)")
print("Saving to: \(shotpath)")
do {
try appshot.pngRepresentation.write(to: shotpathUrl!)
} catch {
print("Failed saving screenshot due to \(error)")
}
This gives me the following output:
Saving to: file:///var/mobile/Containers/Data/Application/77D52C66-353B-4029-97D5-48E6BAE35C92/Downloads/appshot.png
Failed saving screenshot due to Error Domain=NSCocoaErrorDomain Code=4 "The file “appshot.png” doesn’t exist." UserInfo={NSFilePath=///var/mobile/Containers/Data/Application/77D52C66-353B-4029-97D5-48E6BAE35C92/Downloads/appshot.png, NSUnderlyingError=0x1c405bc60 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}
Of course, the file doesn't exist because that's the file I'm trying to create. But /var/mobile doesn't exist on my laptop either -- it looks like the path FileManager is building may exist on the AppleTV device, but I want it on my laptop where my test script is executing.
So I backed out to a much more simple case, and even this is giving me problems:
let str = "This is a test"
let path = "file:///Users/haljor/foo.txt"
let pathUrl = URL(string: path)!
print("Path: \(path)")
print("URL: \(pathUrl)")
do {
try str.write(to: pathUrl, atomically: true, encoding: .utf8)
} catch {
print("Caught error writing to \(pathUrl): \(error)")
}
And here's the output:
Path: file:///Users/haljor/foo.txt
URL: file:///Users/haljor/foo.txt
Caught error writing to file:///Users/haljor/foo.txt: Error Domain=NSCocoaErrorDomain Code=4 "The folder “foo.txt” doesn’t exist." UserInfo={NSURL=file:///Users/haljor/foo.txt, NSUserStringVariant=Folder, NSUnderlyingError=0x1c40553f0 {Error Domain=NSPOSIXErrorDomain Code=2 "No such file or directory"}}
Here, it looks like it's trying to write to a folder at the path I specified, not a file. Clearly there's something I'm not understanding in each of these cases.
I don't really have a preference for whether I use a fully-specified path or something using FileManager -- it just needs to land somewhere on my laptop (not the TV device). What am I missing?
You can add an attachment to the test case and save it to disk too. The problem was that Downloads folder may not exist in the container yet. The best way to handle this is via init-once property:
var downloadsFolder: URL = {
let fm = FileManager.default
let folder = fm.urls(for: .downloadsDirectory, in: .userDomainMask)[0]
var isDirectory: ObjCBool = false
if !(fm.fileExists(atPath: folder.path, isDirectory: &isDirectory) && isDirectory.boolValue) {
try! fm.createDirectory(at: folder, withIntermediateDirectories: false, attributes: nil)
}
return folder
}()
func test() {
let appshot = XCUIScreen.main.screenshot()
let attachment = XCTAttachment(screenshot: appshot)
attachment.lifetime = .keepAlways
self.add(attachment)
// Save to container
let url = downloadsFolder.appendingPathComponent("appshot.png")
try! appshot.pngRepresentation.write(to: url)
}
If you want to view the attachment, right-click on the test case, select Jump to Report and expand the tree. You will see the screenshot eventually:
I'm trying to load an .obj file to create an MDLAsset object in a macOS Swift app. Originally, I was creating the asset like so:
let myAsset = URL(fileURLWithPath: "/Users/me/Development/MyProject/MyApp/Assets.xcassets/arrow.dataset/arrow.obj")
arrowMdl = MDLAsset(url:arrow).object(at: 0)
Obviously that won't work when the app is in production - so, based off this SO answer, I tried adding the .obj file to a bundle, and then load it, like so:
let path: String = Bundle.main.path(forResource: "Arrow", ofType: "bundle")!
do {
let arrowPath = try String(contentsOfFile: path)
}
catch let error as NSError {
print(error.description)
}
However, I keep getting the following error:
Error Domain=NSCocoaErrorDomain Code=257 "The file “Arrow.bundle” couldn’t be opened because you don’t have permission to view it."
I made sure to set the permissions to read/write for everyone.
What am I doing wrong? Or, is there another way to load this asset? It looks as though MDLAsset requires a URL to for it to be initialized: https://developer.apple.com/documentation/modelio/mdlasset
I'm fairly new to Xcode and Swift. I'm trying to create a file called "file.txt" in my Documents directory and getting the error "You don’t have permission to save the file."
Ultimately, I DO NOT want to use the default Documents directory as I'm using FIFinderSyncController to watch everything ("/").
let targetFile = (FIFinderSyncController.default().targetedURL()?.path)! + "/file.txt"
NSLog("%#", targetFile as NSString)
let fileManager = FileManager.default
if fileManager.fileExists( atPath: (targetFile) ) == false {
do {
let targetString = (FIFinderSyncController.default().targetedURL()?.path)! + "/Untitled.txt"
NSLog("%#", targetString as NSString)
let fileManager = FileManager.default
if fileManager.fileExists( atPath: targetString ) == false {
let content = "" // Just creating empty file.
//writing
try content.write(toFile: targetString, atomically: false, encoding: String.Encoding.utf8)
//reading
let readingText = try NSString(contentsOfFile: targetString, encoding: String.Encoding.utf8.rawValue)
NSLog("%#", readingText as NSString)
}
}
catch {
print(error.localizedDescription)
}
}
Log shows:
2017-04-06 13:35:46.450077-0700 Open New Text File[5177:1035580] /Users/david/Documents/file.txt

You don’t have permission to save the file “file.txt” in the folder “Documents”.
I found the answer here so I thought I would help out. The issue is the limitations of sandbox. If you add
com.apple.security.temporary-exception.files.home-relative-path.read-write
To the entitlements file for the target as an Array with strings for the parent folders you want to watch. In my case I just added "/" to watch everything. Here's mine:
<key>com.apple.security.temporary-exception.files.home-relative-path.read-write</key>
<array>
<string>/</string>
</array>
This will allow you to access everything relative to the folder mentioned.
One warning: it seems (not thoroughly tested) that if there are other FIFinderSyncController's set up (in other apps), they can effect each other.
What worked for me in a similar case was to select Read/Write in "User Selected Files" in the Capabilities of the Sandbox.
I had the same issue. I solved it by setting the "App Sandbox" key to "No" in the "Entitlements File".
Hope this will help.
Im using parse to download some files to the device and all is good but i want to then move the file from the default cache directory which is where parse stores them (/Library/Caches/PFFileCache/) to somewhere more stable say the users documents directory.
The localised error i am getting is:
Error: “7b54d8a0f1a64b710058d4408ca4d696_The%20Name%20of%20the%20Wind%2029-92.mp3” couldn’t be moved to “Documents” because either the former doesn't exist, or the folder containing the latter doesn't exist.
But I'm sure both exist. It may be something to do with the name as when i ge the name from the PFFile it doesn't have the encoded %20 in the file name.
This is my code block:
let cachedPFFile = object.object(forKey: "partAudio") as! PFFile
print(cachedPFFile)
let getCachedFilePath = cachedPFFile.getPathInBackground()
getCachedFilePath.waitUntilFinished()
let cachedFilePath = getCachedFilePath.result as! String
print(cachedFilePath)
let paths = FileManager.default.urls(for: .documentDirectory, in: .userDomainMask)
let documentsDirectory = String(describing: paths[0])
let saveDirectory = documentsDirectory.appending(cachedPFFile.name)
print(documentsDirectory)
print(saveDirectory)
let fileManager = FileManager.default
if fileManager.fileExists(atPath: saveDirectory) == false {
do {
try fileManager.moveItem(atPath: cachedFilePath, toPath: saveDirectory)
print("Move successful")
} catch let error {
print("Error: \(error.localizedDescription)")
}
}
This is the entire log:

I am confused by this because both the file and the new directory exist??
though I'm not sure about the "file:///Users" as this doesn't work in finder, have to use the true path "/Users" how can i remove "file://" from the start of the string??
Also I've been searching SO without luck on how to add the %20 in the spaces of the file name none of the obvious options seem to work.
You have threading issues. Your entire idea of "waitUntilFinished" is wrong. You cannot block the main thread — and you are getting a warning telling you so. Listen to that warning!
Do not call getFilePathInBackground, and do not wait for the download to finish. Instead, call getFileInBackgroundWithBlock:, and inside the block proceed with the rest of your code, i.e. move the file.
