Reply to Core Bluetooth - scanning for extended advertising issues
The world of BLE 5.x is strange: Apple I believe iPhone's above 8 have to capability to scan for Advertising Extension - someone correct me if I am wrong (I only have a iPhone 8 on my desk for testing) iOS15.x still doesn't have Coded PHY for long range (Also it seems very hard to place permanently in the background) Setting an Advertising Extension with coded PHY at an interval of say 5 seconds does not eat into the battery life (tested on an Android over a 24 hr period) - well it is BLE after all... Google Pixel phones can't scan for Advertising Extension with Coded PHY- seems like a long running bug and its even in the newer gabeldorsche code base Most other newer Android phones can scan for Advertising Extension with Coded PHY Eg. phones OnePlus 7 and above, Galaxy Tab A7, Galaxy S10 and above, Xiaomi Poco X3 NFC seem to be working fine with Coded PHY scanning. Android Adverting Extension transmission (including Pixel) is working on all devices (well from the last 2-3 years) With this situation i

Is it possible to read NFC tag without the popover?
There's a popover when I use https://developer.apple.com/documentation/corenfc to read the nfcTag, but I don't want that popover. Can I read the nfcTag without popover? I hope that there will be no pop-up window after enabling nfctag reading, and only start processing the obtained information when the correct nfcTag is read. I hope to realize that the user can perform other operations in the application and always open the nfcTag for reading before reading an nfcTag.Is it possible？How should I implement this function？

App clip - disable invocation from previous URL
According to the documentation, for app clips: If a user returns to a previously launched App Clip from the App Library or Spotlight, the App Clip uses the invocation URL that it previously used to launch the App Clip. Is there a way to see whether the invocation URL that is passed to the app is simply the cached URL from a e.g. Spotlight launch vs. whether it has actually come from an app clip invocation method like NFC/QR? Alternatively, is there a way to disable this caching altogether?

NFC not working the second time
I am having a lot of trouble getting NFC to work a second time. The first time using it to read works just fine, but the second time I try it gives me errors about the delegate method not being found. The exact error is this: [CoreNFC] 00000002 8093c3f0 -[NFCTagReaderSession didDetectTags:connectedTagIndex:]:141 Delegate does not implement -tagReaderSession:didDetectTags: method I know that the delegate is set because it is calling the same code. I do invalidate the session after reading. I have stepped through the code and made sure that line is called. Does anyone have any suggestions?

Background NFC Tag Reading in Airplane Mode?
Apple's docs for Background Tag Reading state clearly that: ...be aware there are times when the display is on and background tag reading is unavailable, such as if [...] Airplane mode is enabled. Is anyone aware of the actual reason behind this restriction? Consider these examples: User A visits a different country and doesn't have local cell service. They use WiFi to access the internet, but keep airplane mode on to avoid expensive roaming charges. They apparently need to pay roaming fees in order to scan an NFC tag. User B is actually on a plane (literally the reason for airplane mode). They strike up a conversation with their seatmate, who wants to share contact info using an NFC business card. It won't work until the flight lands. In both of these cases, airplane mode is restricting what seem to be harmless attempts to scan a tag. Further, users don't commonly understand this restriction, and I am at a loss for how to explain Apple's reasoning to frustrated customers. Does anyone have a

NFC Tags won't read after iOS 15.4 update
After updating to iOS 15.4 I can no longer read any NFC tags. I believe Apple Pay is working fine. Replication: Unlock iPhone, hold NFC tag to top back of phone (without case or other magnetic or metallic materials nearby). Default iOS behaviour should be to read the contents of a known working tag (works perfectly on an Android device) and display a popup to manage the tag information (e.g. Popup would ask permission to open Safari to open a web link programmed on a tag) 3rd Party Tools: Previous versions of iOS 15 beta allowed read and write of NFC tags using apps such as NFC and NFC Tools. I have used normal mode, compatibility mode, have attempted to (re)format the tag to no avail. When conducting a read or write using these tools a popup appears, but no tag can be read or written. Ready to Scan popup remains open. Further steps taken: Hard Reset: No effect

Is there an API for third-party apps to use NFC?
Is there an API for third-party apps for using NFC? It's nothing about any payment systems. If an authorization fee is required, please provide a contact person.

Same issue. Can’t read any NFC enabled document anymore. Weird how can you break a functionality like this and not notice it at all.

Reply to NFC not working the second time
I figured this out. It was due to some third party software that I was using for talking with NFC. It expected me to keep a reference to its object.
