Here is another nice plugin from John that extends Xcode providing a live memory browser with an easy to use interface browser that works with apps running in the simulator and device called XprobePlugin.
With XprobePlugin you can search through and filter memory contents, and create trace filters for memory contents.
Here’s an image from the readme showing the XprobePlugin interface in action:
You can find XprobePlugin on Github here.
A very nice addition to Xcode.
Added to the Xcode plugin list.
