Xcode 6.1尚未作为最终版本提供，如此页面，其中表示6.1版本的Xcode将很快推出。

Xcode 6.1 is not yet available as a final release, as evidenced by this page on Apple's website, which says that the 6.1 version of Xcode will be "available shortly."

Xcode 6.1的最终版本将包含iOS 8.1 SDK的最终版本，并允许您将应用程序提交到为该版本SDK构建的App Store。

The final release of Xcode 6.1 will include the final version of the iOS 8.1 SDK and will allow you to submit apps to the App Store that are built for that version of the SDK.

由于iOS 8.1将于周一发布，很可能会在此之前的某个时间发布。

Since iOS 8.1 will be released on Monday, it is likely that it will be released sometime before then.
