CoreNFC, NFCISO7816Tag, alertMessage, timeouts

Dear All,


I'm working on an application to address NFCISO7816Tag with success until now. Here are the limitations that I found and my questions:


1) When starting to scan with a begin reader session, it seems that the scanning has a timeout of 60s ?

Is this statement true ?

Is there any way to customize this timeout ?


2) When starting to communicate with a NFCISO7816Tag, it seems that the communication windows is bound to 20s ?

Is this statement true ?

Is there any way to customize/increase this timeout ?


3) After the beginning the reader session, the NFC UIAlertMessage pops up in foreground. We can update the text with the alertMessage function. This UIAlertMessage exists until the session is invalidated. This behavior prevents having interactions with the user while NFC communications are in place.

Is this right ?

Is there any way to allow user interaction while a reader session is started ? Let say to enter a PIN code for example or to click on a button in some UI ?


If of any interset, I'm currently using Xcode 11.4.1, iPhone Xr iOS 13.4.1 and swift.
