Using the `Xcode 14 Command Line Tools`, execute the command `otool -x -V` to disassemble Objective-C and Swift symbols such as `_OBJC_CLASS_$_`, `OBJC_IVAR`, or various method names using `adrp` and `bl` instructions.：

```
but I using `XCode15 Command Line Tool`，`adrp` and `bl` can not disassemb the Objective-C method and Swift symbol：
