Question

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!

Answer 1

1) Use a precompiled header and remove any imports of those files (UIKite, Foundation, Cocoa, etc) which Xcode adds when you create classes)

2) Add reasonable stable user header files in the .pch as well – to reduce the precompile work.
