    How to Download iOS Simulator (Xcode) in Command Line and Install it

For faster connection speed and more flexibility.
Steps


Start Xcode in command line by running this in commandline /Applications/Xcode.app/Contents/MacOS/Xcode
Start downloading of the simulator
Cancel it. YES CANCEL IT!
You will get a message like this:
2015-11-23 17:10:01.906 Xcode[30803:2505495]  DVTDownloadable: Download Cancelled.   Downloadable: https://devimages.apple.com.edgekey.net/downloads/xcode/simulators/com.apple.pkg.iPhoneSimulatorSDK8_3-8.3.1.1428621365.dmg.
Quit Xcode
Use your favorite download tool with the link in that message in step 3


This is what I use: (5 concurrent connection) aria2c -x 5 link_to_the_file


Have Fun!

Wait! How can I install this?

By moving the file to ~/Library/Caches/com.apple.dt.Xcode/Downloads

You can use Finder by open ~/Library/Caches/com.apple.dt.Xcode/Downloads
Or just mv file ~/Library/Caches/com.apple.dt.Xcode/Downloads

And open the Downloads tab in Xcode's Preferences,

the progress bar of the item you just download should be 80% filled
you should be able to click that download button to install the file

Why did I need it?

I am in China right now and when downloading in Xcode(no concurrent downloading), the download speed sucks!
I would like to use aria2 to speed up the downloading process of the simulator(s).
How slow was the connect using Xcode and how fast was it when using aria2?


Xcode: 150KB -> 300KB
aria2: 2.7MB (consistenly), which is the maximum downloading speed of my cable

Why aria2?


Concurrent connections
Resuming unfinished downloads
