How to update the lldb in macosx

Question

My mac is 10.13.4 Beta and the version of the lldb is "lldb-902.0.79.7 switf-4.1".I want to update the lldb but I didn't found any solution.

Answer 1

The LLDB binary in /usr/bin/lldb searches for the LLDB executable inside the Xcode.app bundle using xcode-select internally.

To change which Xcode Application bundle (therefore version) is being used, run sudo xcode-select -s /path/to/an/Xcode.app.

For example:

sudo xcode-select -s /Applications/Xcode9.4.app
