Speeding up compilation in xCode
===

I have a rather large project where compilation takes more than 1 hour on a Mac with i5 processor.
Just changing one little piece of code at one place makes the complete long compilation necessary.


**Is there any way to reduce this time?**

I was thinking about "precompiling of classes" or "pre-linking" if there is anything like that.
Even uploading a little app to a device takes 10 seconds.

ps Anyone can provide some experience whether xCode4.3 is faster on the new Mac Retinas in this context?


Many thanks!
