  • SR-11282 LLDB REPL code completion assertion failure

Issue Description:

When triggering autocomplete in the REPL on a value, whose type is not defined in the Swift standard library or in the session itself, the REPL crashes.

Steps to reproduce:

  1. Start the Swift REPL

  2. execute import Foundation

  3. execute let a: NSArray = []

  4. type in a

  5. press tab to trigger autocomplete

This crashes the REPL and the following error is emitted:
