Using Taplinx library on iOS with Desfire EV2/EV3 tags

Dear Team,

I am developing an application to format and read data from a DESFire EV3 16KB card.

I followed the UG10045 guide and successfully added both TapLinx and J2ObjC libraries as instructed.

I also disabled the "Debug executable" option in my application map. Passed the license verification step.

However, when I send the SelectApplication or GetFreeMemory command, I get the error as below.

I would love to get some help or guidance to resolve this issue.

Thank you very much,
Manh Vu
