I'm using "guard let self = self else { return }". When debugging with lldb, "po self" throw error. Neither can I use "po self?.xxx" or "po self!.xxx". Any idea?

error: warning: <EXPR>:12:9: warning: initialization of variable '$__lldb_error_result' was never used; consider replacing with assignment to '_' or removing it
    var $__lldb_error_result = __lldb_tmp_error
    ~~~~^~~~~~~~~~~~~~~~~~~~
    _

error: <EXPR>:19:5: error: value of type '*' has no member '$__lldb_wrapped_expr_126'
    $__lldb_injected_self.$__lldb_wrapped_expr_126(

This specific issue has been reported as https://bugs.swift.org/browse/SR-6156, among others.

Also, quoting from Xcode 11 beta 1 release note’s “Resolved issues” section:

Redeclaring self in Swift code works properly with LLDB. (39611934)
