Hello Apple Developer Technical Support Team, I’m working on an iOS banking/security SDK and we’re trying to match an Android feature that reads payment cards via NFC (EMV). On Android, this is implemented using an NFC scanning screen (e.g., “NfcScanActivity”) that can read EMV data from contactless credit/debit cards. Could you please clarify the current iOS capabilities and App Store policy around this? On iOS, is it currently possible for a third-party App Store app to read contactless credit/debit cards using Core NFC (i.e., accessing EMV application data/AIDs from payment cards)? If this is possible, what are the supported APIs/frameworks and any entitlement requirements (if applicable)? If this is not possible for App Store apps, could you recommend the closest acceptable alternatives for achieving a similar user outcome? For example: Using Apple Pay / PassKit flows for payment-related experiences Card scanning alternatives (camera-based OCR) for capturing card details (if allowed) Using an external certified card reader accessory (MFi) and required approach/entitlements Any other Apple-recommended approach for “card verification / identification” without reading EMV NFC data Our goal is not to bypass security restrictions, but to provide a compliant solution on iOS comparable to Android’s NFC-based card reading, or to adopt an Apple-approved alternative if direct EMV reading is not supported. If helpful, I can share a brief technical summary of the Android behavior and the exact data we need to obtain (e.g., whether it’s card presence verification vs. reading specific EMV tags). Thank you for your guidance. Best regards, Imran

Hello, I would like to discuss the behavior of the expiration of NFCPresentmentIntentAssertion (test in iOS 18.5). In the documentation we have : The intent assertion expires if any of the following occur: The intent assertion object deinitializes Your app goes into the background 15 seconds elapse BUT; in fact ; only the 1st rule is applied. The expiration seems to be random after the usage of CardSession and that's difficult to give to the user a good experience. Has someone faced the same kind of issue; or can give an explanation? Regards, François

On the iPad Pro 12.9-inch (3rd generation) cellular model, when you touch the screen with four fingers and then move your fingers, the touch is no longer detected. The same operation with one to three fingers works normally. This phenomenon does not occur when accessibility is turned on. Is this a beta-specific issue that will be fixed in the official release?

Hi, we have developed an application that streams data from two BLE peripherals at a rate of 14.5kbps per peripheral. Until now, our devices streamed in near real time with no lag on all Apple devices with Bluetooth 5.0 or greater. Since the release of the iPhone 17 series and the iPad A16, we have reports from users of the data being streamed at significantly lower rates than expected. Any help here would be greatly appreciated as our customers are being affected by this change.

The FindMy device is currently MFI certified, but we plan to support UWB ranging functionality in the Find My app, similar to AirTag. After searching for relevant information, I found the relevant UWB functions in this article "Nearby-Interaction-Accessory-Protocol-Specification-Release-R4", but we need to develop third-party applications ourselves. So how can we make it display distance and direction in the "Find My" app like AirTag does?

目前这个findmy 设备是已经通过MFI认证，不过后续想的在”Find My “应用上像 AirTag 一样支持UWB测距功能。 寻找了相关资料，在这篇文章《Nearby-Interaction-Accessory-Protocol-Specification-Release-R4》中找到了UWB的相关功能，但是需要我们自己开发第三方应用。 所以需要怎么做才可以做到像airtag 一样在“Find My”应用上显示距离和方向

EASession(accessory:forProtocol:) always returns nil — MFI accessory iAP2 Platform: iOS 17+ | Hardware: Custom MFI-certified accessory (USB-C, iAP2) | Language: Swift Problem We have a custom MFI-certified accessory communicating over USB-C using ExternalAccessory. The app calls EASession(accessory:forProtocol:) after receiving EAAccessoryDidConnect but it always returns nil. We never get past session creation. What we have verified We captured a sysdiagnose on-device and analysed the accessoryd-packets log. The full iAP2 handshake completes successfully at the OS level: USB attach succeeds MFI auth certificate is present and Apple-issued Auth challenge and response complete successfully IdentificationInformation is accepted by iOS — protocol string and Team ID are correct EAAccessoryDidConnect fires as expected iOS sends StartExternalAccessoryProtocolSession — the OS-level session is established So the hardware, MFI auth, protocol string, and Team ID are all correct. Despite this, EASession(accessory:forProtocol:) returns nil in the app. We also confirmed: Protocol string in UISupportedExternalAccessoryProtocols in Info.plist matches the accessory exactly Protocol string in code matches Info.plist App entitlements are correctly configured EAAccessoryManager.shared().registerForLocalNotifications() is called before connection Current connection code @objc private func accessoryDidConnect(_ notification: Notification) { guard let accessory = notification.userInfo?[EAAccessoryKey] as? EAAccessory else { return } DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) { self.tryConnectToAccessory() } } private func tryConnectToAccessory() { DispatchQueue.main.asyncAfter(deadline: .now() + 3.0) { for accessory in EAAccessoryManager.shared().connectedAccessories { let session = EASession(accessory: accessory, forProtocol: "") // session is always nil here } } } Questions The packet log shows a ~4 second gap between EAAccessoryDidConnect firing and iOS internally completing session readiness (StartExternalAccessoryProtocolSession). Is there a reliable way to know when iOS Is it actually ready to grant an EASession, rather than using a fixed delay? Is there a delegate callback or notification that fires when the accessory protocol session is ready to be opened, rather than relying on EAAccessoryDidConnect + an arbitrary delay? Are there any known conditions on iOS 17+ under which EASession returns nil even though the iAP2 handshake completed successfully at the OS level? Is retrying EASession after a nil result a supported pattern, or does a nil result mean the session will never succeed for that connection? Any guidance appreciated.
