I'm pretty sure everyone who has ever used Xcode on Lion knows how unstable it is and how often it crashes. I had the same problem with my MBP and now MBA on and off - sometimes it doesn't crash, sometimes it does :s So how have people made it stable (mine is still annoyingly unstable)? The CPU speeds up to 300%, 90C and fans roar at 6500rpm when I have to force quit... Turning off live code view improved it (for a while) but now it's gone back to its previous state of annoyance. Any suggestions?
