Overview

Hi we do have a functionality where we need to highlight some content. Our functionality was using javascript functions window.getSelection() or document.getSelection(). These were working fine with IOS 14. when our devices were updated to IOS 15, we are getting null for either window.getSelection() or document.getSelection(). Could you please help us to resolve this issue? we appreciate your help.

The app which is archived by XCode 12.5 and running on iOS 15 when I convert HTML to NSAttributedString. (iOS 14 is fine). Here is the crash report.

On three different machines (all running Xcode 13 and Big Sur), it always tells me that the command-line developer tools need to be installed. I've "installed" them four times so far on one machine, and at least twice on the other two.

Hey everyone, does anyone know the size limits for the pop up for extensions for safari for the macOS , iPadOS and iPhone . Can’t seem to find any documentation. Thank you

Do iBeacons work on macOS at all? I see the necessary APIs, but they do not appear to do anything. When I look at the CLLocationManager and other documentation, I see macOS listed as supported. But my experience suggest that it is not.

I am trying to make a simple tvOS app. I was testing some basic SwiftUI code shown here: struct ContentView: View { var body: some View { TabView { NavigationView { NavigationLink(destination: Text("Subview")) { Text("Subview") } } .tabItem { Text("Main") } NavigationView { Text("Settings") } .tabItem { Text("Settings") } } } } ContentView() is called directly from the entry point: @main struct MyApp: App { var body: some Scene { WindowGroup { ContentView() } } } When testing this code on my Apple TV (Apple TV 4K, running tvOS 15.0), the app launches successfully. I can switch between tabs and click on the NavigationLink to go to the subview. However, when pressing the back/menu button on the Apple TV Remote, the app closes with the following error: [Common] Error response from snapshot request action of type 1 gave Error Domain=BSActionErrorDomain Code=1 "(null)" Is this intended behavior? Looking at the resources and documentation online it appears like NavigationViews nested inside TabViews should work as expected. Any feedback about what the error is trying to explain might be helpful too, as the vague output makes it difficult to determine if this is an issue with my SwiftUI code or if it is a bug with tvOS and SwiftUI. Thanks!

Code Example I am trying to call an AppleScript application from a Java program. I found this code example: package com.devdaily.mac.applescript; import java.io.IOException; public class MultilineAppleScriptTest { public static void main(String[] args) { new MultilineAppleScriptTest(); } public MultilineAppleScriptTest() { Runtime runtime = Runtime.getRuntime(); // an applescript command that is multiple lines long. // just create a java string, and remember the newline characters. String applescriptCommand = "tell app \"iTunes\"\n" + "activate\n" + "set sound volume to 40\n" + "set EQ enabled to true\n" + "play\n" + "end tell"; String[] args = { "osascript", "-e", applescriptCommand }; try { Process process = runtime.exec(args); } catch (IOException e) { e.printStackTrace(); } } } Problem When searching for the package "com.devdaily.mac.applescript" it references in Eclipse for installing new software, it does not find the package or even just searching for "applescript" in general. So, this must be a one off custom package the author created. Any ideas on locating this package OR do you know of any other examples I can try that performs a similar purpose? Thank you!

Hi, When packaging an application using JDK 17 and the latest version of jpackage I get the below error when uploading to the App Store. All test prior to uploading complete just fine. I think it might be realated to the structure of the .app folder but not sure, any ideas would be helpful ITMS-90238: Invalid Signature - The main app bundle Test at path Test.app has following signing error(s): a sealed resource is missing or invalid.

From what I can see it's doing all the right things when signing etc. Thanks Ryan

I'm new to async/await, and am currently migrating my completion handler code to Swift 5.5's concurrency features. After generating an sync alternative in Xcode to my function func fetchMatchRecords(completion: @escaping ([Match]) -> Void), it becomes func fetchMatchRecords() async -> [Match]. I'm not sure how it would be used in the context of UIKit and diffable data sources. In a viewDidLoad, previously it would be MatchHistoryController.shared.fetchMatchRecords() { matches in DispatchQueue.main.async { self.dataSource.apply(self.initialSnapshot(), animatingDifferences: false) } } But I'm not sure how it would be used now Task { await MatchHistoryController.shared.fetchMatchRecords() } self.dataSource.apply(self.initialSnapshot(), animatingDifferences: false) How would I make sure that the snapshot is applied only after awaiting a successful fetch result? Here's the definition of initialSnapshot() that I used: func initialSnapshot() -> NSDiffableDataSourceSnapshot<Section, Match> { var snapshot = NSDiffableDataSourceSnapshot<Section, Match>() snapshot.appendSections([.main]) snapshot.appendItems(MatchHistoryController.shared.matches) return snapshot }

When I setup Share extension or Action extension on iOS to import a Vcard into my app it works great but when running the app on Mac catalyst I'm left with a Vcard at the bottom of my screen and I can't close it or do anything, deleting the app and reinstalling doesn't even fix it, I'm going to have to format my computer. How do I deal with these? the just keep building up, How do I make sure my app doesn't do this? How do I close the ones that are open, I'm stuck. Theres a few things I tried. The .plist option to 'Supports Document Browser' is set to 'No' 'Supports opening documents in place' has to be se to 'Yes' or not included for a Mac Catalyst app or I get this error - error: 'LSSupportsOpeningDocumentsInPlace = NO' is not supported on macOS. Either remove the entry or set it to YES, and also ensure that the application does open documents in place on macOS. What I'm thinking is I did not ensure that the app did not open a document in place? Now I have no idea how to undo what I've done. Its just stuck there, attached to my app somehow. I tried deleting the app and all the files associated to the app I could find, but its still there. How do I prevent this from happening but still get all the card info into my app. it does work to populate the card info into my app, its just this thing here is not closing or I don't want that to happen, that's probably what the error is warning me about.

I'm trying to implement custom NSTextContentManager and use it with NSTextView, however it seems that NSTextView expect NSTextContentStorage all the time. final class MyTextContentManager: NSTextContentManager { // ... } It's added to layout manager, and NSTextView instance finds it properly: let textContentManager = MyTextContentManager() textContentManager.addTextLayoutManager(textLayoutManager) however, when I use it, I see errors at: [MyTextContentManager textStorage]: unrecognized selector sent to instance 0x600003d84870 the textStorage property is part of NSTextStorageObserving, that is not NSTextContentManager interface. It looks like NSTextView is not ready to work with custom NSTextContentManager. What did I miss?

We were DFU-Library to upload firmware to our BLE accessory earlier. But our new set of accessories doesn't support DFU library and we need to upload the firmware to an OTA service in its respective characteristics and we does the same using following code, var offset = 0 var bytesToSend = fromData.count let packetSize = BoardInformationService.packetSize var chunkArray: [Data] = [] repeat { let chunkLength = min(bytesToSend, packetSize) let chunk = fromData.subdata(in: Int(offset) ..< Int(offset + chunkLength)) chunkArray.append(chunk) offset += chunkLength bytesToSend -= chunkLength } while bytesToSend > 0 print("BT: Total Chunk size:\(chunkArray.count)") return chunkArray } func uploadNextChunk() { if let firmwareCharacteristic = fileCharacteristic { print("Found fileCharacteristic to upload") if self.currentPacket < self.totalNumberOfPackets { // Send next chunk let nextPacket = self.fileByteChunkArray[self.currentPacket] print("BT: current packet uploading: \(self.currentPacket)/\(self.totalNumberOfPackets) Data:\(nextPacket)") self.currentPacket += 1 // Write to peripheral BTDiscovery.sharedInstance().peripheralBLE.writeValue(nextPacket, for: firmwareCharacteristic, type: .withResponse) } else { updateCompleteCompletion!() } } else { print("No fileCharacteristic to upload") } } // This is a delegate method which gets called when we get response from our peripheral after sending each packet. func ackReceivedFromPeripheral() { uploadNextChunk() } But this doesn't work on iOS but the same approach working on Android. Can you please guide me what could be wrong here.
