How can I set LLDB's default language to Swift?

Question

I have a large Swift project that's technically a mixed project, as it has a small amount of Objective-C code. But whenever I drop into LLDB, the expression evaluator is expecting Objective-C syntax. I can use Swift with e -l swift -- but this is tedious to type every time.

Can I default the LLDB expression evaluator to Swift?

There is a target level setting to force the language:

(lldb) settings set target.language swift

Or you can make an alias for swift specific expressions:

command alias es expression -l swift --

Jim or @Bill is there any way I can add `command alias es expression -l swift --` to some alias table so it is persistent on every xCode debug session? – J. Doe Feb 23 '19 at 13:09
Save it to ~/.llbinit – Bill Feb 23 '19 at 13:10
