[swift-users] Swift REPL broken after updating to Sierra, is it just me?

[Jens Persson]

Thanks! I moved the following to a temporary location:
~
├── .lldb
│   ├── lldb-history
│   ├── lldb-repl-history
│   └── lldb-swift-history
└── .lldb-swift-history

And that made the REPL work again.
I will zip and attach those files to 28657007.
