App Clip Not Launching – Correct Bundle ID and AASA, Still Not Working
Hi everyone, I’m trying to launch an App Clip for my app, and I’ve been stuck trying to debug why the App Clip won’t launch in production, despite everything seemingly being set up correctly. My setup: Main app bundle ID: com.release.cosa App Clip bundle ID in Xcode: com.release.cosa.appclip In App Store Connect, the App Clip is listed as: com.release.cosa.appclip My AASA file (served with correct headers from my domain): { "appclips": { "apps": ["com.release.cosa.appclip"] } } App Clip target and entitlements are properly set in Xcode What works: App Clip launches via local testing in Xcode (Simulator and physical device) App Clip works when triggered manually from Safari (while debugging) What doesn’t work: NFC tag or Universal Link from the real world does not trigger the App Clip On device, nothing happens – not even a fallback to Safari No errors shown to user

Can an iPhone be used as an NFC terminal to read Apple Wallet passes from another iPhone?
Hi all, I'm working on a use case where a customer checks in at a point of service (e.g., a cafeteria or restaurant) using their Apple Wallet pass (e.g., a digital employee badge). In this scenario, we would like to use an iPhone (with a custom iOS app) as the NFC terminal to read the pass directly from the customer's iPhone over NFC. I’m aware that "Tap to Pay on iPhone" allows NFC-based payment acceptance, but it’s unclear if similar functionality is available or permitted for reading access-type passes from another iPhone via NFC. Key questions: Is it technically possible for an iPhone to act as an NFC reader for a Wallet pass on another iPhone? If not, is this restricted due to Secure Element isolation or protocol limitations? Is there any Apple-supported path for building such a solution — or is certified external hardware (e.g., HID, Wavelynx) the only option? I’ve reviewed the Core NFC and PassKit documentation but couldn't find a definitive answer. Thanks in advance for your clarification!

I received the following message in my email: Please correct the following issues and upload a new binary to App Store Connect. ITMS-90714: Invalid binary - The app contains one or more corrupted binaries. Please rebuild the app and resubmit. But I don't know how to find the problem. How should I find and solve the problem?
