I'm trying to create swift macros for initializer. I can't get the members of the inherited class.

So I'm looking inside the documentation for TipKit, which ~1400 lines in a single file of documentation. If I right click a symbol there is no "Jump to Definition" in the context menu. Steps to reproduce: Navigate to TipKit generated "header". Right click a symbol like Tip (highlighted in bold): public struct AnyTip : Tip 3rd step) No Jump to Definition menu item appears in the context menu. Is this intentional behavior?

Xcode 15 and Sonoma expose the property NSView.clipsToBounds. On Sonoma I need to set this property to TRUE and this is working well. However, for reasons, I also need to compile my macOS project with Xcode 13 and Xcode 14. I am having difficulty figuring out the Swift #available and @available directives to allow this. No matter how I wrap the self.clipsToBounds = true statement, on these earlier versions of Xcode I get a Swift error telling me that clipsToBounds cannot be found. Any help would be appreciated.

I'm using the latest Playground app (version 4.3.1) and Xcode 15. I'd like to practice code that supports iOS 12 and above. Is there a way to set the deployment target in either the standalone Playground app or within Xcode playgrounds?

Hello, I am using swift to develop an app. I created a new swift file called PDFkithelper it is in the same folder but the viewcontroller is not recognizing it. can I get help? This is For view controller.

Hey, I need the information about the access-points/devices of the connected Wifi network, I repeat only of the **connected Wifi network ** My use caes is about the indoor positioning of a user connect the network and for that I need the information of all the access points (e.g. ssid, bssid, rssi etc.) but till now I am unable to find any starting point/solution for this. Any help regarding this will be highly appreciated. Regards, Aqeel Ahmed

I need to get all devices names which are connected to same wifi. I tried NetServiceBrowser, in netServiceBrowser(_ browser: NetServiceBrowser, didFind service: NetService, moreComing: Bool) function I get some devices name like Macbook or iPad with search service type of browser.searchForServices(ofType: "_services._dns-sd._udp.", inDomain: "local.") But in this service type I cant get iPhones. I'm not sure if this is the right way, which framework should I use to accomplish this? Am I on the right track? What permits do I need to get? I need your help. Best regards.

I am building a tokeniser, and would like to hold this as a struct, passing in a locale during initiation. Here's the gist of what I would want to write: struct Tokeniser { private let locale: Locale private let integerRegex: Regex init(locale: Locale) { self.locale: Locale self.integerRegex = Regex { Capture { .localizedInteger(locale: locale) } transform: { Token.number($0) } } } func parse(text: String) -> Token { if let match = try integerRegex.firstMatch(in: text) { //... other code here } } \\...other code here } As Regex is generic the compiler suggests to set the integerRegex's type to Regex<Any>, but this triggers another set of compiler issues that I have not been able to figure out what the type should be. So then I tried to write something like this (inspired by SwiftUI): var integerRegex: some Regex { Capture { .localizedInteger(locale: locale) } transform: { Token.number($0) } } But again, the compiler prompts me to enter Regex. The only way I have to be able to get the struct to compiler is to create lazy variables, which then have the side effect that I have to mark my functions as mutable, which have downstream issues when they are called from with SwiftUI structs. lazy var integerRegex = Regex { Capture { .localizedInteger(locale: locale) } } mutating func parse(text: String) -> Token { if let match = try integerRegex.firstMatch(in: text) { } } How can I code this?

I am trying to play multiple HLS streams with AVPlayer. Starting with 4 cameras it is working fine but whenever I change cameras, it stuck with AVPlayer.TimeControlStatus.waitingToPlayAtSpecifiedRate. it is working fine with iOS 15 but having issues with iOS 16 and 17. I have checked it with different network speeds. So bandwidth is fine.

I want to access to a small number of Markdown text files. It looks like the asset catalog feature "Folder with Namespace" might do well, as I could store these small files in a folder that the asset catalog contains. How would I go about getting the string contents of a particular file if I know its name?

Hi, I'm having some trouble running a shell script that worked before I updated the Xcode and my MacOS. This is probably connected to the command line tools which were updated with these upgrades. I can't switch to an older version of the command line tools to verify this theory tho... The script uses CryptoKit to decrypt some data which was encrypted using a SymmetricKey. The script: #!/bin/bash # # DecryptScript.sh # # This script decrypts encrypted data using a symmetric key. # Check for the correct number of arguments if [ "$#" -ne 2 ]; then echo "Usage: $0 <encrypted_file_path> <decrypted_file_path>" exit 1 fi # Get the input arguments encryptedFilePath="$1" decryptedFilePath="$2" # Find the path to the script's directory scriptDir="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )" # Check if the symmetric key file exists in the same directory symmetricKeyPath="$scriptDir/.sim.key" if [ ! -f "$symmetricKeyPath" ]; then echo "SymmetricKey file was not found in the same directory as the script." exit 1 fi # Decrypt the data swift - <<EOF import Foundation import CryptoKit let symmetricKeyURL = URL(fileURLWithPath: "$symmetricKeyPath") let encryptedDataURL = URL(fileURLWithPath: "$encryptedFilePath") let decryptedDataURL = URL(fileURLWithPath: "$decryptedFilePath") guard let symmetricKeyData = try?

Data(contentsOf: encryptedDataURL) else { fatalError("Failed to read encrypted data") } do { // Decrypt the data using AES-GCM let decryptionKey = SymmetricKey(data: symmetricKeyData) let sealedBox = try AES.GCM.SealedBox(combined: encryptedData) let decryptedData = try AES.GCM.open(sealedBox, using: decryptionKey) // Write the decrypted data to a file try decryptedData.write(to: decryptedDataURL) print("Decryption successful.

I also found this thread where someone had the same issue but with a different framework. NOTE: If I try to decrypt the data in my project, it works without any issues even on Xcode 15. It only fails if I try to run this script which worked before when I had the previous version of command line tools. I even tried updating to Xcode 15.1 beta and its command line tools, without success. Any feedback is appreciated. Thank you.

I'm playing around with custom actor executors a bit ... as seen in What's new in Swift at WWDC 2023... The following code errors out: @available(iOS 17.0, *) actor TestActor { private let queue: DispatchSerialQueue nonisolated var unownedExecutor: UnownedSerialExecutor { queue.asUnownedSerialExecutor() } ... Value of type 'DispatchSerialQueue' has no member 'asUnownedSerialExecutor' There is the _DispatchSerialExecutorQueue that actually does provide the asUnownedSerialExecutor() function ... This conflicts a bit with what Doug said during the talk... "The synchronization of actors via dispatch queues is made possible because dispatch queue conforms to the new SerialExecutor protocol." https://developer.apple.com/wwdc23/10164?time=2206

Hi Everyone, I have enabled eSIM entitlements to check eSIM, but I am always getting false for supportsCellularPlan and supportsEmbeddedSIM although my device having the esim feature. I followed each step from this stack overflow answer https://stackoverflow.com/a/60162323 Can anyone help me out here? below is the code I used:- private let provisioning = CTCellularPlanProvisioning() let ctpr = CTCellularPlanProvisioningRequest() ctpr.address = "address$" ctpr.matchingID = "string$" let supportsESIM = provisioning.supportsCellularPlan() if #available(iOS 12.0, *) { let ctcp = CTCellularPlanProvisioning() ctcp.addPlan(with: ctpr) { (result) in switch result { case .unknown: print("Sorry unknown error") case .fail: print("Oops! something went wrong") case .success: print("Yay! eSIM installed successfully") @unknown default: print("Oops! something went wrong") } } } print(provisioning.supportsEmbeddedSIM) print(supportsESIM) this is the entitlements SS this is the info.plist SS

Hi All, I have a Swift Package I'm building. I need to import an existing C++ Static Library into this package. It seems to build fine, but when I attempt to run the tests I get a weird linker error. I've put a repro repo up at https://github.com/flighttactics/CppIssueRepro Here's the steps I took: I have the C++ library's .a file and the headers. I created a folder in my package for the library, drug the include folder into it, and then added the .a file at the root of the folder. I created an Umbrella header in the include folder, along with a module.modulemap. I then created a shim file (per https://github.com/apple/swift-package-manager/issues/5706) Finally, I modified my package file to build the target, and reference it as a dependency (Note I also had to go into the GeographicLib headers for DST and comment out two functions I'm not using which reference std::function since that's not supported by Swift) I find that including the library module works in the main code base, and I can build successfully. However, when I attempt to run tests against the main code base when it's calling into the C++ library I'm getting the following build error: ld: Undefined symbols: double GeographicLib::Math::AngNormalize<double>(double), referenced from: GeographicLib::GeoCoords::Reset(double, double, int) in CppIssueRepro.o GeographicLib::UTMUPS::Forward(double, double, int&, bool&, double&, double&, double&, double&, int, bool), referenced from: GeographicLib::GeoCoords::Reset(double, double, int) in CppIssueRepro.o GeographicLib::GeoCoords::MGRSRepresentation(int) const, referenced from: CppIssueRepro.CoordinateCalculator.coverttoMGRS(lat: Swift.Double, lon: Swift.Double) -> Swift.String in CppIssueRepro.o clang: error: linker command failed with exit code 1 (use -v to see invocation) Again, if my main code does not call into the C++ library I'm able to run tests and build just fine. Not sure what else I can do - it seems like I'm following everything based on the 5.9 docs but I also feel I'm maybe missing something really simple here.

Hi Everyone, I'm having a strange crash on App launch with iOS16 when I have a reference to an iOS17 only framework in my code. Even if I wrap the code in #available, I still get the crash on launch; and the code isn't even called yet... just the existence of it causes the crash. Pretty strange I thought? The framework is VisionKit, and the code that causes the crash is if #available(iOS 17, *) { // .imageSubject is iOS17 only - but this causes // a crash on launch in iOS16 even with the #available check interaction.preferredInteractionTypes = .imageSubject } The crash is: Referenced from: &lt;91ED5216-D66C-3649-91DA-B31C0B55DDA1&gt; /private/var/containers/Bundle/Application/78FD9C93-5657-4FF5-85E7-A44B60717870/XXXXXX.app/XXXXXX Expected in: &lt;AF01C435-3C37-3C7C-84D9-9B5EA3A59F5C&gt; /System/Library/Frameworks/VisionKit.framework/VisionKit Any thoughts anyone?? I know the .imageSubject is iOS17 only, but the #available should catch it - no? Any why does it crash immediatley on launch, when that code is not even called? Odd!

I would like to be able to use multiple gestures against a number of images. In the code below, when I use the tap (3 times) gesture, it works correctly off the clicked card, same with the long press. However, when I try to drag 1 image, all of them are dragged together. I guess it has something to do with being in the ForEach view? Thanks for looking at this and helping me get out of the rut I have dragged myself into! Here is the code (you can use any images to test, I used playing cards): import SwiftUI struct ContentView: View { enum DragState { case inactive case dragging(translation: CGSize) var translation: CGSize { switch self { case .dragging(let translation): return translation default:return CGSize.zero}}} @GestureState var pressing: Bool = false @GestureState var dragState = DragState.inactive @State var viewDragState = CGSize.zero @State var p1Hand: [String] = ["2_of_hearts", "3_of_hearts", "4_of_hearts", "5_of_hearts"] @State var discardDeck: [String] = [] @State var p1TM1: [String] = [] @State var expand: Bool = false var translationOffset: CGSize { return CGSize(width: viewDragState.width + dragState.translation.width, height: viewDragState.height + dragState.translation.height)} var body: some View { ZStack { ForEach(0..<p1Hand.count, id: \.self) { cardIndex in CardView (card: p1Hand[cardIndex], cardIndex: cardIndex) // 3 taps to move to different array .onTapGesture(count: 3, perform: { discardDeck.append(p1Hand[cardIndex]) print("discard: \(discardDeck)") }) // long press put in another array .gesture(LongPressGesture(minimumDuration: 1) .updating($pressing) {value,state,transaction in state = value transaction.animation = Animation.easeInOut(duration: 0.5) } .onEnded { value in expand = true p1TM1.append(p1Hand[cardIndex]) print("p1TM1: \(p1TM1)") }) // drag card to group .gesture(DragGesture(minimumDistance: 5) .updating($dragState) { value, state, translation in state = .dragging(translation: value.translation) }.onEnded { value in self.viewDragState.height += value.translation.height self.viewDragState.width += value.translation.width print("card(s) dragged") }) .offset(translationOffset) } } } } struct CardView: View { var card: String var cardIndex: Int var body: some View { Image(card) .resizable() .frame(width: 40, height: 60) .position(x: 40 + CGFloat(cardIndex * 25), y:75) } } #Preview { ContentView() }
