#xc-launch

This is a small script to launch Xcode using a RAM disk to store intermediate build products files, normally found in `DerivedData`.

#Motivation

After some time using Xcode, the DerivedData folder tends to grow. In my secondary development machine takes now 1.8 GB. Creating all these files in a RAM Disk destroys everything after switching off your machine (or ejecting the drive). Also, if you have enough memory, it speeds up compiling (everything happens in RAM)

This problem is shown here:

Also, in [this StackOverflow](http://stackoverflow.com/questions/18933321/deleting-contents-from-xcode-derived-data-folder) discussion

#Installation

1. Just copy this script somewhere in your PATH, for instance to `/usr/local/bin` (using for example `cp xc-launch.sh /usr/local/bin`)
2. Grant it executable permissions: `chmod a+x xc-launch.sh`

To make use of it, you __need__ to change your Xcode preferences 

1. Go to Xcode > Preferences > Locations
2. Point Derived Data to /Volumes/ramdisk

You don't need to be root to run this :-)

When you finish, eject your ramdisk using the Finder.
