Detect and get uID Mifare DesFire Ev3 card on IOS (swift).

[congpt]

Hi all!
Can someone help me? I have several Mifare DesFire Ev3 cards. I am trying to detect and get the UID of a card on my IOS app but it fails.

Here's what I'm doing:

@available(iOS 13, *)

    func beginScanning() {

        let sessiont = NFCTagReaderSession(pollingOption: .iso14443, delegate: self)

        sessiont.alertMessage = "vID.startSS.holdWn".localizableString()

        sessiont.begin()

    }

    @available(iOS 13, *)

    func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) {

        LogVM.log("Read tag:")

        if case let NFCTag.miFare(tag) = tags.first! {

            LogVM.log("=> Is tag mife:")

            LogVM.log(tag.identifier.hexEncodedString(options: .upperCase))

        }

    }

When I touch the ev3 tag it doesn't even jump to the "didDetect tags" function and "LogVM.log("Read tag:")".

The code works great with my ev2 tag, it easily detects the tag and gets the uID on the ev2 tag.

How can I detect Ev3 tags?
Note: I tried detecting it on NXP's "Tag Info" application. It detected that it was indeed a Mifare DesFire Ev3 card.

Hello @congpt ,

We are just IC supplier, only can provide documentation regarding Mifare DESFire EV3, for iOS development issue, you have to ask for help from Apple.
