Many iOS apps today are clients of some sort. They request data from a remote server. Typically this data is served over HTTP (with SSL) and formatted as JSON. At FastModel Sports our iOS app is constantly requesting large amounts of JSON data. While debugging the app I inevitably have to compare what I’m displaying in my views to what the server sent me.
This meant saving the server response into an NSString, printing it out to the console with NSLog, copying that output, switching to Terminal, pasting that output into a file and then running
jq on that file. That’s a lot of steps. In this post I’ll show you how to do all of that directly from the LLDB command prompt.
