Overview

I am trying to create a near real-time drawing of waveform data from within a SwiftUI app. The data is streaming in from the hardware and I've verified that the draw(in ctx: CGContext) override in my custom CALayer is getting called. I have added this custom CALayer class as a sublayer to a UIView instance that I am making available via the UIViewRepresentable protocol. The only time I see updated output from the CALayer is when I rotate the device and layout happens (I assume). How can I force SwiftUI to update every time I render new data in my CALayer? More Info: I'm porting an app from the Windows desktop. Previously, I tried to make this work by simply generating a new UIImage from a CGContext every time I wanted to update the display. I quickly exhausted memory with that technique because a new context is being created every time I call UIGraphicsImageRenderer(size:).image { context in }. What I really wanted was something equivalent to a GDI WritableBitmap. Apparently this animal allows a programmer to continuously update and re-use the contents. I could not figure out how to do this in Swift without dropping down to the old CGBitmapContext stuff written in C and even then I wasn't sure if that would give me a reusable context that I could output in SwiftUI each time I refreshed it. CALayer seemed like the answer. I welcome any feedback on a better way to do what I'm trying to accomplish.

I am trying to migrate some of my mapkit code to the Map Server API. My JWT is fine and I can use that within the API Playground just fine. However, when I try to implement a test using PHP and cURL to get my Map token, I receive a 401 Not Authorized Error. My code is below: <?php $URL="https://maps-api.apple.com/v1/token"; $accesstoken = "<MY TOKEN HERE>"; $authorization = 'Authorization: Bearer'.$accesstoken; $headers = []; $ch = curl_init($URL); curl_setopt($ch, CURLOPT_HTTPHEADER, [$authorization]); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_HEADERFUNCTION, function($curl, $header) use (&$headers) { $len = strlen($header); $header = explode(':', $header, 2); if (count($header) < 2) // ignore invalid headers return $len; $headers[strtolower(trim($header[0]))][] = trim($header[1]); return $len; } ); $result=curl_exec($ch); $status_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); //get status code curl_close ($ch); print_r($headers); echo($result); echo($status_code); ?> Now the exact response that I am receiving is: Array ( [date] => Array ( [0] => Thu, 18 Apr 2024 18:32:15 GMT ) [content-type] => Array ( [0] => application/json;charset=utf8 ) [content-length] => Array ( [0] => 51 ) [connection] => Array ( [0] => keep-alive ) [cache-control] => Array ( [0] => max-age=0 ) [x-rid] => Array ( [0] => c9507281-bc32-46ac-be3b-dc59e97e7fed ) [strict-transport-security] => Array ( [0] => max-age=31536000; includeSubDomains; ) ) {"error":{"message":"Not Authorized","details":[]}} 401 Any help getting this to work would be appreciated.

I'm implementing a bitonic sort in Metal with a Swift app. This requires 100's kernel dispatch calls for each of the swap stages which touch the whole array, the work required by the GPU is small. I haven't been able to get this to run fast enough in Swift and it seems its due to a high overhead for each dispatchThread command. I rewrote the test program in Objective C with a super-simple kernel function and its runs 25x faster from Objective C! Kernel function kernel void fill(device uint8_t *array [[buffer(0)]], const device uint32_t &N [[buffer(1)]], const device uint8_t &value [[buffer(2)]], uint i [[thread_position_in_grid]]) { if (i < N) { array[i] = value; } } The Swift code is: func fill(pso:MTLComputePipelineState, buffer:MTLBuffer, N: Int, passes: Int) { guard let commandBuffer = commandQueue.makeCommandBuffer() else { return } let gridSize = MTLSizeMake(N, 1, 1) var threadGroupSize = pso.maxTotalThreadsPerThreadgroup if (threadGroupSize > N) { threadGroupSize = N; } let threadgroupSize = MTLSizeMake(threadGroupSize, 1, 1); for pass in 0..<passes { guard let computeEncoder = commandBuffer.makeComputeCommandEncoder() else { return } var value:UInt8 = UInt8(pass); var NN:UInt32 = UInt32(N); computeEncoder.setComputePipelineState(pso) computeEncoder.setBuffer(buffer, offset: 0, index: 0) computeEncoder.setBytes(&NN, length: MemoryLayout<UInt32>.size, index: 1) computeEncoder.setBytes(&value, length: MemoryLayout<UInt8>.size, index: 2) computeEncoder.dispatchThreadgroups(gridSize, threadsPerThreadgroup: threadgroupSize) computeEncoder.endEncoding() } commandBuffer.commit() commandBuffer.waitUntilCompleted() } let device = MTLCreateSystemDefaultDevice()! let library = device.makeDefaultLibrary()! let commandQueue = device.makeCommandQueue()! let funcFill = library.makeFunction(name: "fill")! let pso = try? device.makeComputePipelineState(function: funcFill) var N = 16384 let passes = 100 let buffer = device.makeBuffer(length:N, options: [.storageModePrivate])! for _ in 1...10 { let startTime = DispatchTime.now() fill(pso:pso!, buffer:buffer, N:N, passes:passes) let endTime = DispatchTime.now() let elapsedTime = endTime.uptimeNanoseconds - startTime.uptimeNanoseconds print("Elapsed time:", Float(elapsedTime)/1_000_000, "ms"); } and the Objective C code (which should be almost identical) is void fill(id<MTLCommandQueue> commandQueue, id<MTLComputePipelineState> funcPSO, id<MTLBuffer> A, uint32_t N, int passes) { id<MTLCommandBuffer> commandBuffer = [commandQueue commandBuffer]; MTLSize gridSize = MTLSizeMake(N, 1, 1); NSUInteger threadGroupSize = funcPSO.maxTotalThreadsPerThreadgroup; if (threadGroupSize > N) { threadGroupSize = N; } MTLSize threadgroupSize = MTLSizeMake(threadGroupSize, 1, 1); for(uint8_t pass=0; pass<passes; pass++) { id<MTLComputeCommandEncoder> computeEncoder = [commandBuffer computeCommandEncoder]; [computeEncoder setComputePipelineState:funcPSO]; [computeEncoder setBuffer:A offset:0 atIndex:0]; [computeEncoder setBytes:&N length:sizeof(uint32_t) atIndex:1]; [computeEncoder setBytes:&pass length:sizeof(uint8_t) atIndex:2]; [computeEncoder dispatchThreads:gridSize threadsPerThreadgroup:threadgroupSize]; [computeEncoder endEncoding]; } [commandBuffer commit]; [commandBuffer waitUntilCompleted]; } int main() { NSError *error; id<MTLDevice> device = MTLCreateSystemDefaultDevice(); id<MTLLibrary> library = [device newDefaultLibrary]; id<MTLCommandQueue> commandQueue = [device newCommandQueue]; id<MTLFunction> funcFill = [library newFunctionWithName:@"fill"]; id<MTLComputePipelineState> pso = [device newComputePipelineStateWithFunction:funcFill error:&error]; // Prepare data int N = 16384; int passes = 100; id<MTLBuffer> bufferA = [device newBufferWithLength:N options:MTLResourceStorageModePrivate]; for(int it=1; it<=10; it++) { CFTimeInterval startTime = CFAbsoluteTimeGetCurrent(); fill(commandQueue, pso, bufferA, N, passes); CFTimeInterval duration = CFAbsoluteTimeGetCurrent() - startTime; NSLog(@"Elapsed time: %.1f ms", 1000*duration); } } The Swift output is: Elapsed time: 89.35556 ms Elapsed time: 63.243744 ms Elapsed time: 62.39568 ms Elapsed time: 62.183224 ms Elapsed time: 63.741913 ms Elapsed time: 63.59463 ms Elapsed time: 62.378654 ms Elapsed time: 61.746098 ms Elapsed time: 61.530384 ms Elapsed time: 60.88774 ms The objective C output is 2024-04-18 19:27:45.704 compute_test[3489:92754] Elapsed time: 3.6 ms 2024-04-18 19:27:45.706 compute_test[3489:92754] Elapsed time: 2.6 ms 2024-04-18 19:27:45.709 compute_test[3489:92754] Elapsed time: 2.6 ms 2024-04-18 19:27:45.712 compute_test[3489:92754] Elapsed time: 2.6 ms 2024-04-18 19:27:45.714 compute_test[3489:92754] Elapsed time: 2.7 ms 2024-04-18 19:27:45.717 compute_test[3489:92754] Elapsed time: 2.8 ms 2024-04-18 19:27:45.720 compute_test[3489:92754] Elapsed time: 2.8 ms 2024-04-18 19:27:45.723 compute_test[3489:92754] Elapsed time: 2.7 ms 2024-04-18 19:27:45.726 compute_test[3489:92754] Elapsed time: 2.5 ms 2024-04-18 19:27:45.728 compute_test[3489:92754] Elapsed time: 2.5 ms I compile the Swift code for Release, optimised for speed. I can't believe there should be a difference here, so what could be different, and what might I be doing wrong? thanks Adrian

I'm building a Mac OSX Menubar app (build target is 14.0) and need a Settings window as part of it. I define the window as a standalone view in my @main block as follows: struct xyzApp: App { MenuBarExtra { MenubarView() } label: { Label("XYZ", image: "xyz") } .menuBarExtraStyle(.window) Window("Settings", id: "settings-window") { SettingsView() }.windowResizability(.contentSize) } The Settings view looks like this var body: some View { TabView { Form { }.tabItem { Label("Tab1",systemImage: "gear") } Form { }.tabItem { Label("Tab2",systemImage: "gear") } } } } However the Tabview is not being rendered correctly, there's no image and the sizing is wrong I tested the same code on a regular app with a Settings() declaration in the @main block and it works fine. Any points on what I'm doing wrong would be very helpful. Thanks!

I know apple updated their policy related to sign in (see https://developer.apple.com/news/?id=f1v8pyay, "More flexibility for sign in options in apps" section), but the wording of the guidelines (https://developer.apple.com/app-store/review/guidelines/#login-services) is a bit difficult to understand: Apps that use a third-party or social login service (such as Facebook Login, Google Sign-In, Sign in with Twitter, Sign In with LinkedIn, Login with Amazon, or WeChat Login) to set up or authenticate the user’s primary account with the app must also offer as an equivalent option another login service with the following features: the login service limits data collection to the user’s name and email address; the login service allows users to keep their email address private as part of setting up their account; and the login service does not collect interactions with your app for advertising purposes without consent. As far as I can tell, FB, Google, Amazon, etc. do not offer these protections. Would Apple Sign In still be required in this case?

I'm trying to build a project with a moderately complex Reality Composer Pro project, but am unable to because my Mac mini (2023, 8GB RAM) keeps running out of memory. I'm wondering if there are any known memory leaks in realitytool, but basically the tool is taking up 20-30GB (!) memory during builds. I have a Mac Pro for content creation, which is why I didn't go for more RAM on the mini – it was supposed to just be a build machine for Apple Silicon compatibility, as my Pro is Intel. But, I'm kinda stuck here. I have a scene that builds fine, but any time I had a USD – in this case a tree asset – with lots of instances, or a lot of geometry, I run into the memory issue. I've tried greatly simplifying the model, but even a 2MB USD is resulting in the crash. I'm failing to see how adding a 2MB asset would cause the memory of realitytool to balloon so much during builds. If someone from Apple is willing to look, I can provide the scene – but it's proprietary so I can't just post it publicly here.

Hello, I'm trying to get a better understanding of the SMS.db tables and fields. Does anybody have a document that describes each table and the fields within that table? I'd like to understand what each field in the Messages Table is used for but it would be a bonus if the is info is also available for the other tables contained in the SMS.db as well.

Hi everyone, I'm working on submitting my app to the App Store and need to capture screenshots for the 5.5-inch iPhone display size (iPhone 6 Plus, 7 Plus, and 8 Plus). Unfortunately, Xcode 17.4 doesn't offer simulators for these devices. I've searched Apple's support resources but haven't found any solutions. Would anyone have suggestions on how to generate the required 5.5-inch screenshots for App Store submission? Thanks in advance for your help!

I want to distribute my app as unlisted, review team also recommends me this. 12th of April I submitted the request and got bot mail about awaiting maximum of 3 business days. I has been carrying about this all this time, so that submitted another one request yesterday. Review team always replies very fast in hours, but apple support which is processing my request confuses me. Is here somebody with same trouble or how much time have you been awaiting for feedback? P.S.: I can wait, but I don't see any progress and afraid of non-processing of my request because there was notification about max 3 days of awaiting, but at least a week has been gone.

Description says this event will be raised when "An identifier for a process that notifies endpoint security that it is updating a file." What does this mean ? Similarly when will ES_EVENT_TYPE_NOTIFY_FILE_PROVIDER_MATERIALIZE event be raised ? Do these events get raised if any cloud provider sync app like Google Drive/Dropbox/OneDrive that usages fileprovider framework to sync the data ? In my endpoint secutiry app, I have registered for these events but i didnt receive any event *i do receive other endpoint secutiry events like ES_EVENT_TYPE_NOTIFY_CLONE etc.

Hello, I uploaded my app for review and the status is "waiting review", I have tried many things since March 28th, creating a new review, requesting support for feedback,... and nothing. Does anyone know what I should do to get feedback or a deadline for publishing my app? Thanks in advance Leonardo

Hi, I was working on some new filtering logic for my Content Filter that I would like to add. It involves making requests to remote DNS resolvers. Is it possible to use it within sync override func handleNewFlow(_ flow: NEFilterFlow) -> NEFilterNewFlowVerdict of the NEFilterDataProvider? As of right now, I have a concept working in Command Line Tool and playground, however, when I try to add working module to the main project, it's not working (connections are not loading). Function that makes requests to the servers: In this function I use DispatchGroup and notify for non-main queue @available(iOS 12, *) public class NetworkService { private let nonMainQueue: DispatchQueue = DispatchQueue(label: "non-main-queue") func isBlocked(hostname: String, completion: @escaping (Bool) -> Void) { var isAnyBlocked = false let group = DispatchGroup() for server in servers { group.enter() let endpoint = NWEndpoint.Host(server) query(host: endpoint, domain: hostname, queue: .global()) { response, error in defer { group.leave() } /* * some code that determines the filtering logic * if condition is true => isAnyBlocked = true & return */ } } group.notify(queue: nonMainQueue) { completion(isAnyBlocked) } } } And, for example, in playground Semaphores make it work as expected, but the same approach doesn't work with the NEFilterDataProvider playground code sample let hostname = "google.com" func returnResponse() -> String { var result = "" let semaphore = DispatchSemaphore(value: 0) DispatchQueue.global().async { NetworkService.isBlocked(hostname: hostname) { isBlocked in result = isBlocked ? "blocked" : "allowed" semaphore.signal() } } semaphore.wait() return result } print(returnResponse()) Output: allowed

Hi, I'm trying to achieve the following OpenSSL workflow in Swift. I have this intermediate certificate from Let's encrypt and I want to extract the public key from it and then hash it with SHA-256 and finally encide it in base64. The OpenSSL commands that achieve this look like this: openssl x509 -in isrgrootx1.pem -pubkey -noout > publickey.pem openssl rsa -pubin -in publickey.pem -outform der | openssl dgst -sha256 -binary | openssl enc -base64 I've tried Security, CommonCrypto, CryptoKit frameworks with no success. I was able to get the public key out of the certificate but its PEM representation seems to slightly differ from what I get with OpenSSL. At the beginning of the public jet, the OpenSSL version has a string that is not present on what I get with Swift but the rest is the same. This is the Swift code to use: import Foundation import Security import CommonCrypto // Step 1: Extract public key from the certificate func extractPublicKey(from certificate: SecCertificate) -> SecKey? { // Extract public key from the certificate var publicKey: SecKey? if let publicKeyRef = SecCertificateCopyKey(certificate) { publicKey = publicKeyRef } return publicKey } // Step 2: Calculate SHA-256 hash of the public key func calculateSHA256(of data: Data) -> Data { var hash = [UInt8](repeating: 0, count: Int(CC_SHA256_DIGEST_LENGTH)) data.withUnsafeBytes { _ = CC_SHA256($0.baseAddress, CC_LONG(data.count), &hash) } return Data(hash) } // Step 3: Encode data as base64 func base64EncodedString(from data: Data) -> String { return data.base64EncodedString() } // Step 4: Main function to perform all steps func processCertificate(certificate: SecCertificate) { // Step 1: Extract public key guard let publicKey = extractPublicKey(from: certificate) else { return } // Step 2: Export public key as data guard let publicKeyData = SecKeyCopyExternalRepresentation(publicKey, nil) as Data? else { print("Failed to export public key data") return } // Step 3: Calculate SHA-256 hash of the public key let sha256Hash = calculateSHA256(of: publicKeyData) // Step 4: Encode SHA-256 hash as base64 let base64EncodedHash = base64EncodedString(from: sha256Hash) print("SHA-256 hash of public key (base64 encoded): \(base64EncodedHash)") } This is the Public Key I get with OpenSSL: -----BEGIN PUBLIC KEY----- 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 -----END PUBLIC KEY----- and this is what I get with Swift: -----BEGIN PUBLIC KEY----- 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 -----END PUBLIC KEY----- Interestingly, if I use the Swift version of the Public Key I get and then run the second command I still get the correct final result.

MacOS Version: 14.3 (23D56) In my testing of PacketTunnelProvider on MacOS I have observed that when I do a system shutdown or reboot, PacketTunnelProvider::stopTunnelWithReason() is getting called with reason: NEProviderStopReasonUserInitiated. Note: when I try to disconnect the VPN from system settings PacketTunnelProvider::stopTunnelWithReason() is called with the same reason: NEProviderStopReasonUserInitiated. I am facing an issue here to identify what caused PacketTunnelProvider::stopTunnelWithReason(), system shutdown or any user action?

I would like to specify "Connection: close" for a request that I load in WKWebView - which actually CAN be done by setting the value on the request that is loaded (and it actually works). However, the documentation at https://developer.apple.com/documentation/foundation/nsurlrequest#1776617 states that it shouldn't be used because the URL loading system handles persistent connections for you. So - my question is how can I indicate to the URL Loading System that I do NOT want to use persistent connections for this particular request? Or - am I safe to just set the header even though it's listed as reserved (because - as mentioned - it does work)?

Hello everyone, I have a app for Driver to pay in-store (fuel, garage, etc.) and would like to build a feature that can activate Apple Pay from my app so that Driver can use it to pay with POS terminal instead of double click the Home button. Is it possible?
