upper code is communication bluetooth classic part of esp32 bluetooth classic communication. i need to make a ios app code(swift or swiftUI) to receive data sent from above esp32 code.

if it is , then i can make a ios app that Gatt over classic, so i can receive data that was sent by ESP32 which use bluetooth classic ( arduino file includes "bluetoothSerial.h") if i made a code that use gatt over classic ? is there any code for this style ?

my ios app receive several format data from ESP32 Module that use Bluetooth Classic.(it is arduino file made by arduinoIDE) after receiving data, i just show data as chart at my ios app, and save it to local sqlite3 db at ios phone. i already made this code with Bluetooth Low energy , but my customer want me to make code with Bluetooth classic the reason of this demand is many phone use rather bluetooth classic phones than bluetooth low energy phones.

oh my god.... , so, how can i this ? can' t we make a bluetooth classic swift app ?

and then.... https://developer.apple.com/documentation/corebluetooth/using_core_bluetooth_classic what is this ? https://developer.apple.com/videos/play/wwdc2019/901 and what is this ?
