QNearFieldManager can't dectection ?

[sgsm]

Use Qt Nfc API to develop applications on IOS. The main purpose is to read and write nfc tags,

develop tools : QtCreater 9.0.3
platForm: macos ventrual
qt ver:qt 6.4.2
IOS : 16.1

code :
nfm = new QNearFieldManager(this);

nfcAdapterAvailable = nfm->isEnabled(); // return true

if(nfcAdapterAvailable)
{
    showUserTip("NFC Adapter is ready");

    //开始监听
    if(nfm->startTargetDetection(QNearFieldTarget::AnyAccess))
    {
       showUserTip("begin detection...");

       connect(nfm, &QNearFieldManager::targetDetected,this, &MainWindow::targetDetected);

       connect(nfm, &QNearFieldManager::targetLost,this, &MainWindow::targetLost);
    }
    else
    {
       showUserTip("detection wrong");
    }
}
else
{
    showUserTip("NFC Adapter not find");
}

}

question:
1、nfm->startTargetDetection（QNearFieldTarget::AnyAccess） always return false ,I can't dection,and I cant't go next

ask :
Why? what will i can do

Is the NFC api simply not available on IOS?

@ekkescorner Thank you. Although I am prepared, I am still disappointed. I have no choice but to learn swift on xcode
