Crash on Simulator when doing TTP payment

[haphanquang]

I got exception with the sdk when attempting a payment on a Simulator

2023-08-31 11:18:11.313270+0900 FiservTTPTestApp[65914:4015735] Swift/StringCharacterView.swift:153: Fatal error: String index is out of bounds

This is the .generalCardData as based64 I got c2ltLWdjZA==
Seems like the length field of TLV data is too long or the .generalCardData is not TLV when doing payment on Simulator.

Please take a look.

Thanks for using our SDK. Currently, using the simulator is not supported when using Apple TTP.
