App Clip Unavailable
I have published the app on the App Store along with its corresponding app clip, my app clip is configured with some advanced experiences for each one of my clients, but whenever some users try to scan an NFC or QR Code they see the card rendering correctly with their configured banner image, but with the message App Clip Unavailable. The weird thing is that both iMessage and the website to which the associated domain is set and the apple-app-site-association is stored, renders the banner or card correctly, and when the users tap the banner or card they open the advanced app clip experience correctly without any issue. I have attempted to troubleshoot the issue by checking the following: if the app clip is below 15MB if we are using a second level domain in my associated domain both for my app clip and app (excluding the www subdomain). checking if the AASA is correctly stored inside .well-known directory checking the configuration for the advanced experience I opened a case: 102233443873, and added

iPad app with NFC and camera - No compatible hardware
I'm working on an app (actually in Test Flight) that has camera and NFC support. So in iPhone is obviously working as expected, but when testers want to try the camera aspect of the app on iPads they can't even download the app it says No compatible hardware in Test Flight. What I need to do in this case, I already have a UI/UX solution when theres no NFC support or it's disabled (Android can detect this) but here I have no clue if I'm missing something. Thanks in advance

Reply to Apple Watch NFC Tags
I was postponing the watch purchase, but then I just went for it because of all the things I intended on using it - the NFC tags and automation were up there in the top 5. Didn't even cross my mind that there was a possibility of it not working on the watch...eh. Everyone wants this, and You can make it happen Apple <3

Reply to Using Wallet.app to open doors with NFC reader
Through our work at getkisi.com, have a bit of experience with this topic: We manufacture NFC card / mobile readers and also allow to enroll 3rd party NFC cards including credit cards: https://docs.kisi.io/references/credentials/physical_credentials/third_party_nfc_credentials?_highlight=nfc When using credit card wallets such as Apple Wallet or crypto related wallets like you suggest, those will encrypt the credit card number and require a security decoding at the receiving end - in this case the NFC wall reader. The only way to use NFC based cards on wallets on Apple devices is via Apple Wallet as outlined here: https://www.getkisi.com/guides/apple-wallet-access

Reply to Using Wallet.app to open doors with NFC reader
While I want Apple to support this natively, this may be possible using a small NFC tag under your phone's case or attached to the back. Something like this: https://taptag.shop/products/tap-tag-hyperslim. (The price is ridiculous, but I guess they know they have a niche thing that people want.) It essentially doesn't use the iPhone's NFC chip. I don't have one of these (yet) and am not sure if this would affect Qi charging or have any other ill effect.

Flutter NFC tranceive comands
Hi there. I am using flutter_nfc_kit (https://pub.dev/packages/flutter_nfc_kit) to make application that sends bytes to NFC module using tranceive commands, but really often system respond with error 500 or 103... Is there anything in this package that I can change for my commands to work fine? Cause now when I try to scan data it takes minimum like 30 seconds whereas on Android it takes like 7-10 seconds every time Thanks for any feedback

Reply to Client certificate authentication using CTK extension in iOS device
What is difference between Smartcard extension and Persistent Token extension? A persistent token extension allows you to create an entirely virtual token. A smart card extension is meant to present a smart card interface, with cards being inserted and removed, APDU stuff, and so on. Which one I should use? That depends on much your reader looks like a traditional smart card reader. It sounds like it’s very close, in which case a smart card extension would make sense. Since my smartcard reader has lightening port, curious to know if EAAccessory is allowed to be used in CTK extension? I don’t know. This is more of an EA question than a CTK question, and that’s not an area in which I maintain expertise. I know that some CTK extensions do the crypto in their container app rather than in the appex. This is necessary for technologies, like Core NFC, where the API only works in an app. That process is rather convoluted, but it does work. I helped a developer go down that path once, and my final advice was

Signing code with a hardware-based code-signing identity
Both the codesign tool and Xcode allow you to sign code with a hardware-based code-signing identity. However, setting that up can be a bit of a challenge. Recently a developer open a DTS tech support incident requesting help with this, and so I thought I’d post my instructions here for the benefit of all. If you have any questions or comments about this, please start a new thread, tagging it with Code Signing so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = eskimo + 1 + @ + apple.com Signing code with a hardware-based code-signing identity Both the codesign tool and Xcode allow you to sign code with a hardware-based code-signing identity. This post explains how to set that up. I used macOS 14.2.1 with Xcode 15.2. For my hardware-based key I used a YubiKey 5 NFC that I reset to its defaults. I installed YubiKey Manager 1.2.5. IMPORTANT While I used a YubiKey, the code signing parts of this process should work with any token that has a function
