Write content of variable to file with LLDB
.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}
I am debugging some JSON in Swift and want to know if there is a way to write the content of a variable to file. Consider a trivial example:
let jsonString = "{"name": "John", "age": 21}"
How can I write jsonString to a local file for more detailed examination when pausing for debug with LLDB?

You could call write(toFile:atomically:encoding:). For example
(lldb) call jsonString.write(toFile: "path/to/file", atomically: true, encoding: .utf8)
You could make this more convenient using lldb's regex aliases. For example if you wanted a dump command, to run like this:
(lldb) dump jsonString path/to/file
Put the following into your ~/.lldbinit file to use this dump alias:
command regex dump 's/(.+) (.+)/call %1.write(toFile: "%2", atomically: true, encoding: .utf8)/'
