I have a product already developed using the M24LR64ER

I have a product already developed using the M24LR64ER and I need to read and write using an IPhone 14 with IOS 17, would it be possible to read and write using Swift's "import CoreNFC"?

hi Greidimar,
I'm in charge of developing the iOS NFC Tap application for ST25 and M24LR tags in STMicro. 
Regarding M24LR64, they are not supported by coreNFC. It does not allow you to put the “protocol_extension_flag” necessary for the M24LR16 and M24LR64. So it is not possible to use these two versions with an iPhone (and so, whatever is the iOS NFC application used). 
I encourage you to switch on ST25DV64 tags.
Sorry for inconvenience. 
Br,
