Xcode 15.3 is bugged. Apple rewrote the linker and dropped support for weak symbols.
They fixed in Xcode 15.0 and 15.1 with a new flag and then fixed for good in Xcode 15.2.
Unfortunately, it regressed in 15.3.

Can you check if the problem persist when using Xcode 15.2?

This other issue might give you more information: #42230.

I'm sorry, but this is not supported. last device to support iOS 9 is iPhone 6S and that has been discontinued in 2018.
I strongly suggest you not to target those devices. Nor React Native or any Apple IDE will let you test on those devices.

If fix all local sdk into the project ,run app in iphone of ios13.7 normally but disconected tap app crash

What I understand is that you are:

1. connecting the phone to the laptop
2. Build and run the app on the phone
3. Everything works while the phone is connected
4. Disconnect the cable
5. You observe the crash.

Is that correct? What happen if you launch the app from the phone when it is already disconnected?

Observing a crash when disconnecting the phone from the laptop is normal. Every app, even plain iOS apps witouth React Native present that behavior.
The app should run fine on the device if you launch it from the home menu with the phone disconnected.
