My app went to review and apple rejected my app with crash logs as attached below. When i check the same, the app was running fine on my system. Couldn't figure it out the actual reason for crash. crashlog-E841C543-6D57-453B-9E3D-7106DF9D5131.txt

We've encountered a problem that only occurs on the iPhone 15 Pro Max running the 17.4.1 system. Specifically, when we are operating an app, the phone suddenly goes to a black screen, then the system's loading animation appears, and after the animation ends, the lock screen page appears. The whole phenomenon looks like the phone has restarted, but we haven't found any panic full files in the system logs. Therefore, we are at a loss as to how to solve this problem. Can you offer some assistance? This is a video of the issue occurring：https://watch.wave.video/yg2Oph4n4bfdMQeF

Hi, I'm product designer and I'm looking for HIG for layout recomendations, currently I can't find anything about recommended numbers for spacing/paddings etc.. Did Apple remove this and why?

I find odd that the App Store Connect still requires 5.5" iPhone screenshots of the iPhone 8 Plus, given that this specific phone is no longer supported by the latest release: iOS 17. I am well aware that the iPhone SE still has a similar screen ratio, and that it is still being supported by iOS 17, but it doesn't have the same pixel requirements (1242 x 2208), which means that in order for my app to be even reviewed (which is an iOS 17+ exclusive), I'm gonna have to create images that will then be upscaled to the right dimensions. Am I missing something here, or is it Apple who missed this detail?

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?

When sending HTTP requests to API's, the header is now capitalized Old (iOS 17.4 and before): "headers": { "origin": "https://example.com" } New (iOS 17.5): "headers": { "Origin": "https://example.com" } Is this a bug or intentional? I couldn't find this change anywhere.

I'm developing an iOS app that displays store locations on a map using Apple Maps (MapKit). I've limit the number of icons that can be displayed on the map to 100, but there's still huge performance issues and the app is very laggy even on modern iPhone models. What's the best practice when displaying a large number of icons on a map, should the icons be in PNG format with a small resolution (~10kb) or should the icons be vector (SVG) for best performance? Should I use the MapKit framework for iOS 17 or the UIKit approach?

We are working on a new iOS application utilizing the new iOS 17 APIs, and I have updated Xcode to Xcode 15 Beta, and my iPhone 12 Pro to iOS 17 Beta 2, though this issue was also present on iOS 17 Beta 1. In Xcode, for "Signing and Capabilities" I have my Team set to my personal team, utilizing the "Automatically manage signing" tick. While the app will build and install on my phone, I immediately receive this error, with no popup to trust the developer. Going to Settings > General > VPN and Device Management, I can see my Development Team, and I am able to Trust my team. When trying to then Verify App(s), it tells me it will use my internet connection to verify the application. However, it will then do nothing, with no error, regardless of how many times I attempt to verify. Trying to open the app from my home screen will result in the repeated "Unable to Verify Error". Trying to reset network settings does not result in any change in this behavior, nor does a reset of the phone. I have tried 4 different high quality WiFi networks, as well as a fully connection AT&T cellular LTE connection, and still receive this error. I am running out of diagnostic scenarios, and I'm curious if anyone has found a resolution to this?

We want to display our application name should be suggested on wifi network which are insecure. Similar like following: Please suggest, which class or extension we can use for achieve this.

Hi We are developing iOS app using react native. Vscode is used as IDE. when we build the project in Xcode build is successful. But when we try to run it on Xcode simulator the recent changes are not visible. The build is having only the older changes. Please guide us in resolving this.

Hi all apple devs! I am a young developer who is completely new to everything programming. I am currently trying to develop an app where I want to use visionkit, but I can't for the life of me figure out how to implement its features. I've been stuck on this for several days, so I am now resorting to asking all of you experts for help! Your assistance would be immensely appreciated! I started to develop the app trying to exclusively use swiftUI to futureproof my app. Upon figuring out what visionkit is, to my understanding it is more compatible with UIkit? So I rewrote the part of my code that will use visionkit into a UIkit based view, to simplify the integration of visionkits features. It might just have overcomplicated my code? Can visionkit be easily implemented using only swiftUI? I noticed in the demo on the video tutorial the code is in a viewcontroller not a contentview, is this what makes my image unresponsive? My image is not interactable like her demo in the video, where in my code do I go wrong? Help a noob out! The desired user flow is like this: User selects an image through the "Open camera" or "Open Camera Roll" buttons. Upon selection the UIkit based view opens and the selected image is displayed on it. (This is where I want to implement visionkit features) User interacts with the image by touching on it, if touching on a subject, the subject should be lifted out of the rest of the image and be assigned to the editedImage, which in turn displays only the subject without the background on the contentview. (For now the image is assigned to editedimage by longpressing without any subjectlifting since I cant get visionkit to work as I want) Anyways, here's a code snippet of my peculiar effort to implement subject lifting and visionkit into my app:

Anyone else getting the below issue when using Shopify's SDK for iOS? Seems odd they just released a new version and it already has an issue embedded in the package.

hello everyone, I want to create VPN app with swiftUI but i do not know where to start. I have already created some beautiful UI but now i want to configurate network to connect another country server. any suggestions?

Hello, When I build an XCode project with the Apple Silicon chip, I have some issues. The project contains Pods and Swift Packages. I could not run the application at all and always got the following error: Could not find module '***' for target 'x86_64-apple-ios-simulator'; found: arm64, arm64-apple-ios-simulator, at: *** I try to resolve this issue. Always embed swift standard libraries = YES Build Active Architure Only = YES UIRequiredDeviceCapabilities = armv7 Excluded Architectures > Debug > Any iOS Simulator SDK arm64 add Open Using Rosetta Excluded Architectures > Debug > Any iOS Simulator SDK arm64 remove However, issue always come to me. :( Do you have any solution for this problem ? Thank you by advance !

As of iOS 17 SFSpeechRecognizer.isAvailable returns true, even when recognition tasks cannot be fulfilled and immediately fail with error “Siri and Dictation are disabled”. The same speech recognition code works as expected in iOS 16. In iOS 16, neither Siri or Dictation needed to be enabled to have SpeechRecognition to be available and it works as expected. In the past, once permissions given, only an active network connection is required to have functional SpeechRecognition. There seems to be 2 issues in play: In iOS 17, SFSpeechRecognizer.isAvailable incorrectly returns true, when it can’t fulfil requests. In iOS 17 dictation or Siri being enabled is required to handle SpeechRecognition tasks, while in iOS 17 this isn’t the case. If issue 2. Is expected behaviour (I surely hope not), there is no way to actually query if Siri or dictation is enabled to properly handle those cases in code and inform the user why speech recognition doesn’t work. Expected behaviour: Speech recognition is available when Siri and dictation is disabled SFSpeechRecognizer.isAvailable returns correctly false when no SpeechRecognition requests can be handled. iOS Version 17.0 (21A329) Xcode Version 15.0 (15A240d) Anyone else experiencing the same issues or have a solution? Reported this to Apple as well -> FB13235751

Running through the tutorial on how to sign data using security.framework, I was trying to understand the format Apple is using & wanting for signatures (as this isn't documented anywhere): https://developer.apple.com/documentation/security/certificate_key_and_trust_services/keys/signing_and_verifying?language=objc I've learned the format of the signatures are just ASN.1 objects, with EC signatures being a sequence of the R and S coordinates as ASN.1 integers. However, I am noticing when using SecKeyCreateSignature that either the R or S value will always be prepended with an extra byte. For example: 30 45 02 20 66 B7 4C FB FC A0 26 E9 42 50 E8 B4 E3 A2 99 F1 8B A6 93 31 33 E8 7B 6F 95 D7 28 77 52 41 CC 28 02 21 00 E2 01 CB A1 4C AD 42 20 A2 ^^ why is this here? 66 A5 94 F7 B2 2F 96 13 A8 C5 8B 35 C8 D5 72 A0 3D 41 81 90 3D 5A 91 This is a ASN.1 sequence, first is a 32-byte integer and second is a 33-byte integer. Why is that 00 byte being prepended to the integer? Why is it sometimes the R and sometimes the S? Removing it causes SecKeyVerifySignature to fail, so obviously it's required, but I need to know the logic here as I'm having to hand-craft these ASN.1 objects as all I have are the raw R and S values.

I have a use-case were I want to use the the FQDN (Fully Qualified Domain Name) in IOS-Device, which can be used to connect to a Device instead of using the IP-Address. FQDN will be consisting of the machine-name or host-name (Most common term) and the domain-name of the network i.e network-name (local domain assigned to that device). Which IOS Api can be used Here?

Hello, Our app has an internal job processing queue. All jobs are built as a NSOperation and involve a network request, and they are added to NSOperationQueue. When the app is closed while a request is being sent, the app sometimes crashes, but it also keeps crashing whenever we build the operation again and retry it. This happens rarely, but we can systematically reproduce it after a few tries with many jobs. This issue blocks the queue in our app. I understand if this is an issue deep within the framework, but it would be very useful to at least find a way to work around this issue so the queue can continue processing other jobs. The full crash report is attached. I also submitted a bug report: FB13734737 There seems to be an internal assertion fired in CFNetwork: Assertion failed: (CFReadStreamGetStatus(_stream.get()) == kCFStreamStatusNotOpen) function _onqueue_setupStream_block_invoke file HTTPRequestBody.cpp line 878.

I work on an app that uses a couple 3P SDKs that have their own SDK. My app also uses some of the APIs (UserDefaults) and declares those reasons in it's privacy manifest file. I was under the impression that I should only declare the reasons from my app in it's Privacy Manifest file, and that the 3P SDK reasons would automatically be pulled in (because they include them). Uploading to TestFlight I get warnings that this is not the case. If I only declare my app's reasons, it warns me that the APIs the SDK accesses are not included in the manifest. The only way to get it to work, is manually copying in the same declarations that the 3P SDK has into my own manifest file. Is this the way it's supposed to work? Or should it be generating a holistic manifest automatically for me?
