Add support for creating device with a specific architecture

[lone-necromancer]

Hi, I'm happily using this CLI and i noticed at a recent Xcode upgrade that some of my project needed to run on simulators which run with architecture of arch x86_64.

It would be really nice if "create_device" function had another param called "arch" or something of the sort.

Thanks for the help in advance

Hi,

I don't see how this is possible:

➜  ~ xcrun simctl create
Create a new device.
Usage: simctl create <name> <device type id> [<runtime id>]

	<device type id>    A valid available device type. Find these by running "xcrun simctl list devicetypes".
	                    Examples: ("iPhone X", "com.apple.CoreSimulator.SimDeviceType.iPhone-X")
	<runtime id>        A valid and available runtime. Find these by running "xcrun simctl list runtimes".
	                    If no runtime is specified the newest runtime compatible with the device type is chosen.
	                    Examples: ("watchOS3", "watchOS3.2", "watchOS 3.2", "com.apple.CoreSimulator.SimRuntime.watchOS-3-2",
	                               "/Volumes/path/to/Runtimes/watchOS 3.2.simruntime")
