How to debug an iOS app with lldb on the command line on a device without Xcode

Question

Is is possible to launch and debug one of my iOS apps in development on an iPhone (or other iOS device) without using Xcode?

I would like to do this from the command line using lldb.

I figure that since it can be done with Xcode that it may be possible to debug strictly from within the terminal.

Answer 1

ios-deploy can do that.

brew install node
npm install -g ios-deploy

ios-deploy -d -W -b path/to/foo.app

It will copy the app bundle to your connected device, launch the app, and start an lldb session for the app.

I just tested it right now. OSX 10.12.6, iOS 11.0.2, Xcode 9.0.1.
