Dumping the iOS simulator memory

To audit memory or to debug with external tools it can be useful to get a dump of the running memory of an app.

To do so on a device you'll need a Jailbreak, SSH access, and gdb. See this or this.

If instead you're up to a simulated app, things are easier: apps running in the simulator are actually just native processes on your Mac OS X.

So, how to get a core dump of a Mac OS X process? Sadly gdb can't do so. Mac OS X Internals comes to the rescue with this article.

Generate the list yourself:

$ cd /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS*.sdk/System/Library/Frameworks/UIKit.framework/Headers
$ grep UI_APPEARANCE_SELECTOR ./*     | \
  sed 's/NS_AVAILABLE_IOS(.*)//g'     | \
  sed 's/NS_DEPRECATED_IOS(.*)//g'    | \
  sed 's/API_AVAILABLE(.*)//g'        | \
  sed 's/API_UNAVAILABLE(.*)//g'      | \
 sed 's/UI_APPEARANCE_SELECTOR//g' | \
