Hi, I am working on an iOS app that has a custom document type that can be shared with other devices through Airdrop, iMessages, etc. The app should appear in the "Open In..." menu upon receiving the file however, currently it gets directed straight to the files app. I got this feature to work in a previous iteration of the app in iOS 16 but it no longer works with iOS 17. The feature is also broken with the previous iteration in iOS 17. I have defined the custom document type under both Documents Type and Exported Type Identifiers. I have attached a copy of the info.plist below. My question is how can you make your app appear under the list of apps shown in the "Open In..." menu that appears when receiving files for a custom file type. <plist version="1.0"> <dict> <key>CFBundleDocumentTypes</key> <array> <dict> <key>CFBundleTypeIconSystemGenerated</key> <integer>1</integer> <key>CFBundleTypeName</key> <string>RecordingList</string> <key>CFBundleTypeRole</key> <string>Editor</string> <key>LSHandlerRank</key> <string>Owner</string> <key>LSItemContentTypes</key> <array> <string>com.nikodittmar.MyRaceTimer.recordinglist</string> </array> </dict> </array> <key>UTExportedTypeDeclarations</key> <array> <dict> <key>UTTypeConformsTo</key> <array> <string>public.data</string> </array> <key>UTTypeDescription</key> <string>RecordingList</string> <key>UTTypeIcons</key> <dict/> <key>UTTypeIdentifier</key> <string>com.nikodittmar.MyRaceTimer.recordinglist</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>recordinglist</string> </array> </dict> </dict> </array> <key>UTImportedTypeDeclarations</key> <array> <dict> <key>UTTypeConformsTo</key> <array> <string>public.plain-text</string> </array> <key>UTTypeDescription</key> <string>CSV</string> <key>UTTypeIcons</key> <dict/> <key>UTTypeIdentifier</key> <string>public.comma-separated-values-text</string> <key>UTTypeTagSpecification</key> <dict> <key>public.filename-extension</key> <array> <string>csv</string> </array> <key>public.mime-type</key> <array> <string>text/csv</string> </array> </dict> </dict> </array> </dict> </plist> import UniformTypeIdentifiers extension UTType { static var recordingList: UTType { UTType(exportedAs: "com.nikodittmar.MyRaceTimer.recordinglist") } } Thanks.

Hello everyone, I'm having a little issue with mounting my external hard drive lately. I've tried quite a few methods in hope of getting it to work again, but so far, no luck. I hope someone can help me solve this issue, or those who have the same problem may also share your insights. My external hard drive was working fine about a week ago. But one day, I ejected the hard drive and the icon disappeared, so I thought it was safe to unplug it. When I did, it said the hard drive was not properly removed. It still works fine when I use it the next day, but the same thing happened. It said the drive was not properly removed after I ejected the drive, waited for the icon to disappear, and then unplugged the drive. After that, it never works again, and the attached images are the info I got when I tried to mount or run first aid on this drive. Please help & thank you in advance!

Hello, Anyone know of relevant documentation that captures the difference between vfsStruct.f_fsid and fstat.st_ino ? sys/stat.h declares: ino_t st_ino; /* [XSI] File serial number */ AND sys/statvfs.h declares: unsigned long f_fsid; /* Filesystem ID */ Based on some tests, it seems that the st_ino is the number/inode_number that the filesystem identifies the file-resource by ? I observed that this number gets a unique value when I copy a file even when the Finder/FS utilizes the Space-Saver feature of MacOS. This value is identical to the results returned by the command ls "-i" . When copying via Finder, I am seeing distinct st_ino values for source and destination files. f_fsid seems to be identifying the File differently though, perhaps taking into account what Data/attributes objects the file resource points to ? I observed that this number gets an identical value when I copy a file even when the Finder/FS utilizes the Space-Saver feature of MacOS. So, the value of f_fsid seems to be copied over to the destination file record. Also, I could not find a way to display f_fsid via the ls command. On a related note, Any documentation regarding MacOS Finder/FS's Space-Saver feature or how it is implemented ? Thanks, Vikram.S.Warraich

Hey my iphone 12 battery drains so fast . Please help me ho w can i overcome this.

Hi, I stumbled about the Swift Student Challenge at Apples Website and now I have some questions. I've programmed some Apps in Xcode and I think one of them might be pretty god for this Challenge. Now I've read something about Swift Playgrounds and I'm confused. What's a Swift Playground? Do I need to create one or is it enough to have the App? and finally: I'm currently 14 and live in Germany. Is it possible to participate when I'm 14? And if not would it be a big thing to lets say forget my age and somehow think that I'm 16? Thanks a lot for answers

When pressing out of the application menu in Cubase 10.0.60 (presumably running in Rosetta 2), is has recently started to crash and I suspect it's due to an OS update. macOS 14.2 (23C64) Crash report

We have noticed that after the iOS 17 update, there has been a sudden increase in the data for “Discarded - Token Unregistered.” In the statistics for error codes returned by the APNs service, the number of http code 200 has increased, while the number of error code 410 has decreased. Have there been any recent updates to this service?

Hello, I don't understand what is /System/Applications/ folder (macOS Sonoma). It is not an (hard)link to /Applications/. /Applications/ is not a (hard)link to /System/Applications/ Can anyone explain me what is /System/Applications/ ? Isn't it redundant to /Applications/ ? Thanks

I'm trying to update my OS from Big Sur. I had 16GB of free space available, but I can't install the OS update. Looks like there are 20GB worth of APFS snapshots on my 120GB SSD drive. That's absurd. This is what they are called, according to tmutil. com.apple.os.update-51D425C3F73C05488FE6273A584E6DADB9CFAAD5AEB57007C65CE78C69F4AEE1 com.apple.os.update-MSUPrepareUpdate How do I get rid of them? Lots of posts talk about using DiskUtility, but I don't seem to be able to do that. I turned off automatic Time Machine backups, and there don't seem to be any (none above have dates), but I'm still stuck. And the free space keeps getting less and less and the APFS Snapshot volume appears to be increasing in size as I watch it. What can I do?

I have a UIImageView that will serve as a drawing canvas and i want to implement a function that will get the content inside of UIImageView and convert it into a cgContect so it could be set as a background for the canvas to draw over but i ran into an issue. I have a reset button that will set the UIImageView.image to nil (to clear the current UIview) for that I tried to save the UIImageView into a canvasArray array to save it into a second view savedImageView this is my reset function that will delete the content of mainImageView @objc func resetPressed(_ sender: Any) { mainImageView.image = nil } The array that will is store and object that receives mainImageView as a param and the function that saved it var canvasArray: [Canvas] = [] @objc func saveCanvas(_ sender: Any) {. //here is the UIImageView guard let canvas = Canvas(name: "", canvas: mainImageView, numOfPages: 0) else { return } canvasArray.append(canvas) if canvasArray.count > 0 { canvasArray.forEach{ canvas in print("\(canvas.canvas.image)") } } } And the function that will get the iUIImageView.image and will convert it into cgContext @objc func changeImagefunc(_ sender: Any) { if canvasArray.count < pages { return } if let savedImage = canvasArray[pages].canvas.image { UIGraphicsBeginImageContext(view.frame.size) savedImage.draw(in: view.bounds) if let drawnImage = UIGraphicsGetImageFromCurrentImageContext() { mainImageView.image = drawnImage } UIGraphicsEndImageContext() print("clicked button ") } } I have 3 different UIViewImage that will ser a specific purpose mainImageView and tempImageView that will check the start and and of the drawing (function(which works fine) and the savedImageView that will receive the image converted into "cgContext " . Three of them stored in a function that then gets passed into the viewDidLoad section func setupImageViews() { view.addSubview(tempImageView) tempImageView.frame = view.bounds if savedImageView.image != nil { view.addSubview(savedImageView) savedImageView.frame = view.bounds } else { view.addSubview(mainImageView) mainImageView.frame = view.bounds } } Like I said i can not get this to work because the resetButton/function is deleted not only the current UIImageView (which is what is intended to do ) but also deletes the content inside the canvasArray which I want to avoid. Would there ve a different approach to it or what else do you recommend?

I am writing a code to capture the accelerometer data for one hour, it suppose to save in the iOS device first, and then I would like to upload to cloudkit. Here is my code. import UIKit import CoreMotion import CloudKit class ViewController: UIViewController { @IBOutlet weak var accelerometerSwitch: UISwitch! private let recorder = CMSensorRecorder() private let cloudKitContainer = CKContainer(identifier: "iCloud.com.example.accelerometer-recorder") override func viewDidLoad() { super.viewDidLoad() accelerometerSwitch.addTarget(self, action: #selector(accelerometerSwitchValueChanged), for: .valueChanged) } private func saveDataToAppFolder(data: [CMSensorRecordingData]) { let fileName = "accelerometer_data.dat" let fileManager = FileManager.default let documentsDirectoryURL = fileManager.urls(for: .documentDirectory, in: .userDomainMask).first! let fileURL = documentsDirectoryURL.appendingPathComponent(fileName) let jsonData = try! JSONEncoder().encode(data) try! jsonData.write(to: fileURL) } @objc private func accelerometerSwitchValueChanged() { if accelerometerSwitch.isOn { recorder.recordAccelerometer(forDuration: 3600.0) { sensorData in if let sensorData = sensorData { // Handle the recorded data saveDataToAppFolder(data: sensorData) uploadDataToCloudKit(data: sensorData) } else { print("No accelerometer data recorded") } } } else { // No need to stop recording since it will stop automatically after the duration } } private func uploadDataToCloudKit(filePath: String) { let fileURL = URL(fileURLWithPath: filePath) let data = try! Data(contentsOf: fileURL) let record = CKRecord(recordType: "RecordedData") record["data"] = data let database = cloudKitContainer.publicCloudDatabase database.save(record, completionHandler: { record, error in if let error = error { print("Error uploading data to CloudKit: \(error)") } else { print("Data uploaded to CloudKit successfully") } }) } } Anyone can help to fix the error. Thanks a lot.

I working on a drawing app using UIKit and I am trying to create a function that receives a UIImageView as an argument detects the color and then return that UIImageView updated. For example the UIImageView.image will contains a set of UIColors s and my detectColor will check if the image contains .systemGrey then will take any pixel that contains that specific color and change it to .systemPink and return the UIImageView updated For a beter explation here is an example of my function with pseudo code: func updateColor(_ imageView: UIImageView ) -> UIImageView { //.. initialize imageView //... if imageView.image color has pixels in .systemGrey color then //... change that color to .systemPink //... return updated imageView } Like I said I only want to change that specific color taking into account that in some cases my UIImageView.image multiple UIColors .Any Ideas, examples or suggestions will be much appreciated. Thanks!.
