Sign In With Apple _ Invalid client
Hello, I am at wits' end with the Apple Sign-in api. I have tested in stage and it works beautifully, but when i push to production it gives me the error "invalid_client". I'm confident the setup is correct, when I asked Apple for help over the phone, they sent me a few forums with no answers. Has anyone had the same issue? How did you resolve? Could it be because I have two app IDs and two service IDs? (prod + stage) Help!

Securely transmit UIImage to app running on desktop website
Hello everyone, I'm trying to figure out how to transmit a UIImage (png or tiff) securely to an application running in my desktop browser (Mac or PC). The desktop application and iOS app would potentially be running on the same local network (iOS hotspot or something) or have no internet connection at all. I'm trying to securely send over an image that the running desktop app could ingest. I was thinking something like a local server securely accepting image data from an iPhone. Any suggestions ideas or where to look for more info would be greatly appreciated! Thank you for your help.

Receive Custom URL Parameters
Hello! I’m trying to handle custom URLs (e.g., customurl://open?param=value) that open the app. However, while the app launches via the custom URL as expected, the parameters are not being passed to or are accessible from the iOS-specific implementation. Currently, if I open a custom URL via Safari, the app gets launched but the custom URL and parameters are not accessible. customurl://open?hello=test According to the iOS Docs ( https://developer.apple.com/documentation/xcode/defining-a-custom-url-scheme-for-your-app#Handle-incoming-URLs ) any URLs should be passed to: func application(_ application: UIApplication, open url: URL, options: [UIApplication.OpenURLOptionsKey : Any] = [:] ) -> Bool I do not register the above application function to be called but instead this one is executed during app start with launchOptions always being nil: func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool This is the case regardless of if the App is started fresh or was already running in the background. My pInfo entry for the custom URL: <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleTypeRole</key> <string>Viewer</string> <key>CFBundleURLName</key> <string>dev.customurl.project</string> <key>CFBundleURLSchemes</key> <array> <string>customurl</string> </array> </dict> <dict/> </array> TLDR: How can I access the parameters, passed with the URL? Any thoughts on what I am doing wrong?

Auto Dial - 911
My app monitors users heart beats and if critical reading is noticed, it auto -dials 911 for emergency and ambulance help. I was under the impression that auto-dial may not be permitted or possible on the platform. Can anyone confirm and provide any additional guidance on if it is possible in the newer SDK/API stack or using any 3rd party service ? Thank you in advance!!

photos-navigation://album scheme
In my app SexyPeri (https://apps.apple.com/fr/app/id6738291985), I create an album with some pics Album is called SexyPeri Now, I wish to redirect the user from my app SexyPeri DIRECTLY to the album SexyPeri There is no doc about your scheme photos-navigation, or I didn't see it. Some guys retro-engineered it, but I couldn't make this work. photos-navigation://album?name=SexyPeri doesn't work. So my question is: how can I redirect to the album directly ?

Clarification on Opening Main App from Share Extension and App Store Submission
Hello, In our application, we have implemented an app extension to allow users to open the main app directly from the share activity window. To achieve this, we used the openURL(:) method from the NSExtensionContext class, as documented here: openURL(:). However, we received one post from Apple stating that opening the main app directly is typically only supported in extensions such as Today widgets or iMessage apps. They also mentioned that this approach may require an additional review during the App Store submission process. Link: https://developer.apple.com/documentation/foundation/nsextensioncontext/1416791-openurl Could someone clarify: If using openURL(_:) in a share extension to open the main app would lead to potential issues during App Store submission? Are there specific guidelines or alternative approaches we should follow to ensure compliance? Any insights or recommendations would be greatly appreciated. Thank you!

Step-by-Step Guide Needed for NFC Activation in Apple Wallet Pass
Hi everyone, I am working on creating an NFC-enabled Apple Wallet pass but have been unable to get the NFC functionality to work. While the pass itself adds to Wallet without issues, the NFC feature does not activate. Here’s a summary of what I’ve done: 1. Developer Setup: Registered a Pass Type ID in my Apple Developer account. Generated and installed the Pass Type ID certificate. Installed the latest WWDR certificate. 2. Pass JSON Configuration: My pass.json file includes the following NFC configuration: "nfc": { "message": "Tap to unlock door", "encryptionPublicKey": "MY_ENCRYPTION_PUBLIC_KEY", "payload": "encrypted_nfc_payload" } 3. Testing Results: When the pass includes the nfc field, it adds to Wallet but NFC does not work. If I remove the nfc field, the pass works fine (minus NFC, of course). What I Need Help With: 1. A step-by-step guide for correctly implementing NFC in Wallet passes, including details about encryption, key generation, and any additional setup steps. 2. Information on whether there are specific device or iOS version requirements for NFC-enabled passes. If there are any prerequisites or specific configurations I might be missing, please let me know. I’d really appreciate detailed guidance or resources that could help resolve this issue. Thank you!

Software
Here’s a suggestion: Apple should provide a feature for iPhone users to automatically log the specific time and date whenever they reset their phone. This log would allow users to easily track when resets occur. Additionally, Apple could enhance backup options by enabling users to restore any data lost during a reset. This might include automatic backups before each reset or a more intuitive process for recovering previously backed-up data.

iPhone 13 iOS 18 Upgrade Issues: Missing Call Recording and Notes Features
I recently upgraded my iPhone 13 to iOS 18, and I'm facing two issues. I didn't get the call recording feature. When I make a call and the person picks up, the call recording icon is not showing. The option to take notes during a call has disappeared. Earlier, the notes option used to be available on the call screen itself. Please help fix these two issues, or let me know if it's possible to resolve them from my end.

Mobile data error - after iOS 18 update - modem firmware 2.15.01
Hi everyone, I recently updated my iPhone to iOS 18 and have been experiencing significant issues with my cellular network since then. The primary problems include: Random disconnections from the cellular network Frequent "call failed" errors during phone calls After some troubleshooting, I identified that these issues are related to the modem firmware. In an attempt to resolve this, I downgraded my iPhone to iOS 17.6, but the modem firmware remained unchanged and the problems persisted. Today, I updated to iOS 18.1, hoping it might address the issue, but unfortunately, it didn't help either. Has anyone else experienced similar problems? Any suggestions on how to resolve this issue or if there is an expected update to fix this modem firmware problem? Thanks in advance for any help or advice! IPhone 15 pro, iOS 18.1

Need Help in Implementing NFC HCE on iOS Outside EEA
I am developing an app and having trouble implementing NFC HCE functionality on iOS. From what I found, NFC HCE seems possible in the EEA, but I need help doing it in other countries. Is there any way to achieve this through a specific license or certification from Apple? Any guidance or references would be greatly appreciated.
