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.

A common question regarding CocoaPods and Swift is which OS versions are supported.

Swift is supported on OS X 10.9 / iOS 7 and newer, as stated by Apple numerous times.
There is no support for building static archives with Swift (see http://openradar.appspot.com/radar?id=5536341827780608).
Dynamic frameworks are supported on all versions of OS X.
Dynamic frameworks are unsupported on iOS versions prior to 8:

ld: warning: embedded dylibs/frameworks only run on iOS 8 or later.

From this we can conclude that it is not possible to support Swift on any other platforms than OS X 10.9/10.10 and iOS 8.

	# In Chef, when a resource is defined all its variables are evaluated during
	# compile time and the execution of the resource takes place in converge phase.
	# So if the value of a particular attribute is changed in converge
	# (and not in compile) the resource will be executed with the old value.

	# Example problem:
	# Let's consider this situation where there are two steps involved in a recipe
	# Step 1 is a Ruby block that changes a node attribute. Rubyblocks get executed
	# in converge phase
	# Step 2 is a Chef resource that makes use of the node attribute that was
