Apple Releases Xcode 4 GM

Apple just released a GM seed of Xcode 4. It's available now in the iOS and Mac dev centers. The release of the GM seed means the final version of Xcode 4 is nearing completion and should be available soon.

Xcode 4 is a major new version of Apple’s development suite which sports lots of new features and a new single-windowed UI. The first version of Xcode 4 preview was released during the WWDC in June, the second build was seeded in late July, Preview 3 was made available on September 2, Preview 4 was released in October. The latest developer seed, preview 6, was released on January 10.

From the release notes:

Xcode 4 GM seed can now be used to submit iOS and Mac apps to the App Store.

Xcode 4 GM seed includes the iOS SDK 4.2 and Mac OS X SDK 10.6.

The ReadMe file of the GM seed also comes with an interesting notice:

Xcode 4 requires an Intel-based Mac running Mac OS X 10.7 Lion or later.

Which we're sure is just a mistake on the release notes.

Update: it appears that Apple has pulled the GM seed from the developer center, which shows Preview 6 again. Perhaps a bug was found at the last minute, so we guess it should be back shortly.

Update #2: the GM seed is available again in the Dev Center. The OS X 10.7 mention has been removed:

Xcode 4 requires an Intel-based Mac running Mac OS X 10.6.6 or later. See the installation notes below for additional information.
