Cannot Read the Nfc Chip of the Epassport Using iOS13

Cannot read the NFC chip of the ePassport using iOS13

I found the solution I added 00000000000000 to the com.apple.developer.nfc.readersession.iso7816.select-identifiers entry in the Info.plist
Now it looks like this:

<key>com.apple.developer.nfc.readersession.iso7816.select-identifiers</key>
<array>
    <string>A0000002471001</string>
    <string>00000000000000</string>
</array>

Trouble reading eID information with NFC using iOS13

Your func tagReaderSession(_ session: NFCTagReaderSession, didDetect tags: [NFCTag]) implementation looks wrong to me. You are converting an NFCISO7816Tag to an NFCNDEFTag then back to an NFCISO7816Tag.
The implementation should look like this:

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

    let tag = tags.first!

    nfcTagReaderSession?.connect(to: tag) { (error: Error?) in
            if case let .iso7816(iso7816Tag) = tag {
                // do your magic with iso7816Tag here
             }
     }
}

Reading the content of the ePassport/eID NFC chip isn't as straigforward as reading a simple NDEF tag.
The working example provided in Appendix D to Part 11 of the Doc9303 from the ICAO is of great help to understand what needs to be implemented.

For my part I am almost done implementing it in swift and will publish the source code under the MIT license once my app is on the app store.
To do so I included some C/C++ code that was taken from here: https://github.com/UBIC-repo/core/tree/master/PassportReader/Reader

You will probably need to use some bridging to C in order to do the 3DES encryption/decryption and checksum calculations.

EDIT: Someone already posted a working source code here: https://github.com/AndyQ/NFCPassportReader

Missing required entitlement for NFCTagReaderSession

I had the same problem, but it is gone after removing and adding Near Field Communication Tag Reading in Capabilities.

My entitlements file have a little differ:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
    <key>com.apple.developer.associated-domains</key>
    <array>
        <string>applinks:example.com</string>
    </array>
    <key>com.apple.developer.nfc.readersession.formats</key>
    <array>
        <string>NDEF</string>
        <string>TAG</string>
    </array>
</dict>
</plist>

But I don't think this is it.

Also, you can try to modify Apple example to fit your needs: https://developer.apple.com/documentation/corenfc/building_an_nfc_tag-reader_app

Or just remove .iso18092 from polling options and it will work. I think this standard require specific entitlement.
