Reply to CoreNFC problems

Hi Rubenfern, I have the same problem. Even I added the entitlements file but still I get invalid session error. Also I dont even get the system popup window asking for taping the NFC Tag? Could you please let me know if I am missing anything. I updated the info.plist and also enabled NFC Read in AppID in developer account.

Reply to Can't begin NFCNDEFReaderSession, invalidates immediately.

hi ... I am not getting scanning screen popup on my iPhone 7. I did all the prerequisites such as plist, entitlements, enable NFC in appID in dev account, etc.. but not sure where I am going wrong. Whereas I see sometimes Apple Demo App works well. Any clue, please?

iOS11 core NFC : session Timeout

Hi,I have developped a short appli reading NDEF records on NFC tag. All is working fine, excepting scanning behaviour on iPhone :- How to increase scan Timeout of NFC ? It seems to be limited to 1 mn. I need to stop then restart scanning every minute...- Sometimes , RF field is lost whithout any logical reason. Have you already seen that ? Thx for any feedback.

Reply to iOS11 core NFC : session Timeout

Thx all for your feedback.I didn't find any method to increase Timeout of NFC core.API describes maximumRetries and retryInterval for NFCTagCommandConfiguration but I didn't find how to program them.Regarding error returned by delegate functions, func readerSession(_ session: NFCNDEFReaderSession, didInvalidateWithError error: Error) , I always got two kinds of error :Code=201 Session is invalidated due to maximum session timeoutorCode=200 Session is invalidated by user cancellationI don't get any other error, even when RField is lost, or when NDEF cannot be read !!!! Hope it will be fixed in next beta !!!In every case, I need to relauch a session.begin in my appli to re run NFC scan.I will create a thread in my applicaiton to check session.isReady status , and see if it is updated accordingly.I have also viewed another strange behavior :- Run NFC scan near TAG with NDEF => OK- Move iPhone outside TAG for 3s- Try again to read NDEF => KO....RFField is lost. I suspect that iPho

Reply to Open Core NFC for iPads, too

I have the same quesiton for AppleWatch Serie 2.coreNFC framework only availbale for iOS11 and iPhone7.Would it be available in next beta of WatchOS4 ? When playing with appleWatch2 and WatchOS4, my external reader (done with iphone7 and iOS11) detects a NDEF message with a Bluetooth Secure record when launching workout application. It would be mean that workout application is able to configure NFC controller of AppleWatch in Card Emulation Mode....Stay tuned..

Not really sure if NFC is inside some iPad versions, see https://www.ifixit.com/Teardown/iPad+Pro+9.7-Inch+Teardown/60939

Reply to Xcode9 beta: Error on 'Archive' in XCode with CoreNFC

Is Xcode9 beta issues or something I do wrong ?It’s hard to say. If you create a small test project from one of Xcode’s template and put your NFC code in there, does it have the same problem?Share and Enjoy — Quinn “The Eskimo!” Apple Developer Relations, Developer Technical Support, Core OS/Hardware let myEmail = eskimo + 1 + @apple.com
