Where can you download a preview of Xcode 4 from?

I ca开发者_如何学JAVAn't find any reference to it from the Apple website.

Ripped straight from the Apple Dev site:

Xcode 4 Developer Preview Download Now Available

iOS Developer Program members log in to the iOS Dev Center

Mac Developer Program members log in to the Mac Dev Center

You also have to be a member of the ($99/year) Mac Developer Program (as I mentioned in the comments below):

I believe you have to register at developer.apple.com before you can download the preview. From there, it's in the Mac Dev Center.

The preview isn't available anymore. You can either buy it from the Mac store for $4 or enlist as developer for 99$/year and get it free.

The older xcode 3.2.6 is still available for free.
