NFC Scanning Issue on iPhone 11 After Updating to iOS 18
I am experiencing an issue with NFC scanning on my iPhone 11 after updating to iOS 18. Previously, I was able to use NFC tags without any problems. However, since the update, the NFC functionality no longer works as expected. Installed OS: iOS 18.0 (22A3354) Here are the troubleshooting steps I have already tried: Opened the Shortcuts app. Tapped on Automation. Searched for NFC. Selected Run after confirmation. Tapped NFC Tag -> Scan. Unfortunately, nothing happens at this point; the NFC scan doesn't initiate. This issue has made it difficult for me to use NFC-dependent automations and functionalities that worked seamlessly before the update. Could you please provide guidance on how to resolve this problem? Thank you for your attention and support.

AppClip Card image is not appear
I have AppClip set up in AppStoreConnect and it is activated when read by NFC. After trying several times, sometimes the AppClip card does not show up. (I don't think it's a communication speed issue as it doesn't show up after some time). As for the cards, we are only aware of the AppStroeConnect settings. I tried changing the image file of the card to one with a reduced size, but that did not completely resolve the issue. If you have anything to investigate to resolve the issue, I would appreciate it if you could let me know.

Reply to Wallet open while Write NFC
Hello, I'm currently developing an iOS app using CoreNFC that interacts with an RFID reader to facilitate data writing via NFC. My use case involves writing specific NFC tag data to an RFID reader in the context of an electric vehicle charging station that supports multiple RFID standards (ISO/IEC 14443A/B, ISO/IEC 15693, Mifare, FeliCa™, etc.). However, every time I attempt this NFC write operation, the Apple Wallet app opens, preventing my app from completing the NFC session. Here are the details of the issue: I'm using the lower-level NFCISO14443ReaderSession API for direct tag communication, not NDEF. I do not want to create a virtual NFC tag for contactless transactions; I only need to write the NFC tag data to the RFID reader, and the iPhone should act as an initiator, not a tag emulation device. This behavior is consistent, and despite ensuring that I am not working with NDEF tags, the Wallet app is triggered each time. I understand that CoreNFC sup

Apple Wallet Interference During NFC RFID Tag Writing with NFCISO14443ReaderSession
Hello, I am developing an application that involves writing data to RFID tags using NFC (ISO/IEC 14443A/B, Mifare, and FeliCa standards) for an electric vehicle charging station. However, I am consistently facing an issue where the Apple Wallet app is automatically triggered during NFC operations on iOS. This problem occurs every time I attempt to write data to the RFID tags, preventing the application from properly detecting or interacting with the NFC tags. Here are the key details of the issue: Device: iPhone (tested on various models and iOS versions) Issue: Apple Wallet automatically opens during NFC tag writing operations. Expected Behavior: My application should write data to RFID tags without triggering Apple Wallet. RFID Standards: ISO/IEC 14443A/B, Mifare, FeliCa. Code Implementation: I am using the Core NFC framework and NFCISO14443ReaderSession to communicate with the RFID tags. The same code works seamlessly with Android devices, but iOS continuously t

Reply to Wallet open while Write NFC
What API are you using to write the NFC tag data? Basic CoreNFC functionality only allows apps to write to a tag (Creating NFC Tags from Your iPhone). If what you mean by Write Virtual NFC is you want your app to turn into a tag so the reader can interact with it, this is not possible except for very specific use cases. You can read about the capabilities and requirements for these use cases in the following documents: NFC & SE Platform for secure contactless transactions HCE-based contactless transactions for apps in the European Economic Area (EEA) At this time, no other use cases are supported.

Reply to didFinishLaunchingWithOptions is called in background
thank you for reply。 I am sure not using content-available:1 in payload with push notifications。 also our App offers NFC functionality, but it has very few users. from the log,users terminate the app and then didFinishLaunchingWithOptions was called immediately。 I think something was doing in the App, but we have not find them。 the runtime logs from the real user, and i can not reproduce it,and i will log LaunchOptions to find if if has something usefully. The phenomenon is that after the app is terminated, a cold start is immediately triggered in the background. if have more informations, thank you for sharing it.

Reply to didFinishLaunchingWithOptions is called in background
I don't know what you mean the application has not requested background execution. As seen there you have obviously declared Remote Notifications background capability. If you are sending push notifications with the content-available:1 entry in the payload, this will have the ability to launch the app if it is not running at the time (except for if user has terminated it, then it will never launch). That is one possible explanation. Whatever it is, it is likely something you are doing in the app, and not prewarming or some other system function. I also see you are using NFC functionality. Is your app supporting background tag reading? If so, and the app is not running, then didFinishLaunchingWithOptions() will be called before application(_:continue:restorationHandler:) is called Are you not checking the UIApplication.LaunchOptionsKey in didFinishLaunchingWithOptions()? That should explain why your app is being launched. Argun Tekant /  DTS Engineer / Core Technologies

App Clip Invocation Issues on iOS 18 and iOS 18.1 - NFC and QR Invocation not working for Default App Clip Experience
We have identified an issue on iOS 18 and iOS 18.1 (developer beta) where App Clips invoked via NFC or QR codes without a pre-configured Advanced App Clip experience (aka they should be using the Default App Clip Experience) are not functioning as expected. This issue is specific to iOS 18, as the behavior works correctly on iOS devices running 17.x. Steps to Reproduce: Set up two scenarios: One scenario where an App Clip has a pre-configured advanced app clip experience (with metadata such as title, subtitle, image). Another scenario where the App Clip is invoked without any pre-configured experience (should use the default App Clip experience). On an iOS 18 or iOS 18.1 device: For the default App Clip experience (no pre-configured advanced app clip experence): Scan the NFC tag when the phone is locked. Scan the NFC tag when the phone is unlocked. Scan the QR code. For the pre-configured App Clip experience: Perform the same tests (NFC and QR code scans). Test the same sce

App's shortcut actions not showing on iOS 18 shortcuts app
We have developed an iOS app in objective-C and added integrations for shortcuts app - more specific the automation part of the app. Basically, user opens shortcuts app, select automation and when scanning NFC tag, user can select an action and our app shows 3 different actions. User select action, opens the app and action is executed. That all done in Obj-C and was working very well with no complaints till users start to update to iOS18. Now, when user starts to add automation, only thing they can do is select open app. Our app actions are not showing any more. Is there something new in iOS 18 we have to update our app. I know Obje-C is considered old, but the cost of upgrading an existing app and time is not available at the moment.

Host Card Emulation / Card Session for payment URL
We have a financial application where we want to use NFC to broadcast a Payment URL to another iPhone or Android device when initiating a payment transaction. This will then open the banking application installed on the recipient’s device, allowing the transaction to be completed. We have already made the necessary requests to Apple and configured the entitlements file as follows: <key>aps-environment</key> <string>development</string> <key>com.apple.developer.nfc.hce</key> <true/> <key>com.apple.developer.nfc.hce.iso7816.select-identifier-prefixes</key> <array> <string>D2760000850101</string> </array> <key>com.apple.developer.nfc.readersession.formats</key> <array> <string>TAG</string> <string>NDEF</string> </array> </dict> I've tried to use CardSession with the sample code provided by Apple on their site: Card Session The connection between the devices (two iPhones, OS

Express Transit presented despite successful call to PKPassLibrary.requestAutomaticPassPresentationSuppression(...)
I am working on a transit app that offers a digital ticketing product that is powered by a QR code being scanned. We have been successful in preventing the Apple Pay takeover experience from happening when a user tries to use this product next to the tap to pay terminals by making a call to PKPassLibrary.requestAutomaticPassPresentationSuppression(...) before the QR code is presented. However, our transit agency is piloting Express Transit on these turnstiles and we are noticing that this experience overrides the old NFC suppression. Is there a similar method available to us to suppress the express transit experience for users who are using these mobile ticketing products?

Have I encountered a common problem with App clip?
My app contains app clips and it is already available in the app store. After setting up Advanced App Clip Experiences, it has not been able to take effect. I cannot wake up the App clips through the NFC tag containing the link. My Advanced App Clip Experiences status are always Received. I checked everything I could and didn't find any issues, I also saw a lot of people on the developer forums having the same problem but didn't see a solution. Setting->Developer->APP CLIPS TESTING (section)->Diagnostics-> filed my URL, result show below. I can open my App clips by Default App Clip Experiences from Smart App Banner on my website. Do I need to re-upload a new version for App Review, or do I just have to wait? is there a solution?

@mr_app , can you confirm you follow these recommendations from Choosing the right functionality for your App Clip: To ensure a fast launch experience, App Clips must be small:* If you make your App Clip available on devices running iOS 15 and earlier, the uncompressed App Clip binary can be up to 10 MB in size.* If you make your App Clip available on devices running iOS 16 and later, the uncompressed App Clip binary can be up to 15 MB in size.
