Questions tagged [xcode8]

Xcode 8 is an IDE created by Apple for the development of macOS, iOS, watchOS, and tvOS applications. The first release of Xcode 8 was on June 13th, 2016 with Xcode 8 beta build 8S128d. *Do not use this tag unless your question specifically involves the Xcode IDE!*

Xcode 8 is an Apple integrated development environment (IDE). This version of Xcode includes the SDKs for macOS 10.12 iOS 10, watchOS 3, and tvOS. The beta is available free for developers from https://developer.apple.com/ and will be released in the fall from the Mac App Store.

The latest production version of the IDE is Xcode 8.2.1 (8C1002) (Dec 19, 2016)

**Latest Preview : Xcode 8.2 beta 2 (8C30a) released on Nov 14, 2016.

The tag should only be used for questions about the Xcode 8 IDE itself, and not for general macOS, iOS, watchOS, or tvOS programming topics. Use for Mac programming questions, and or for iOS programming questions.

If the question is related to the Xcode IDE in general (not specific to Xcode 8), use the tag.
