Is there a better way to detect if Swift is supported in the current Xcode project than checking for iOS 8 or OSX 10.10?
#if defined(__IPHONE_8_0) || defined(__MAC_10_10)
I have a mixed Swift/Objective-C codebase with two different Xcode projects.

Why do you need to check this? Swift is interoperable with Objective-C. – jtbandes Jun 23 '14 at 23:24

Note that you do not need `iOS 8` or `10.9` to use Swift. You can use at least `iOS 6` and `10.4`. http://stackoverflow.com/questions/24001778/do-swift-based-apps-work-on-os-x-10-9-ios-7-and-lower – Eliza Wilson Jun 24 '14 at 00:13

Yes the resulting binaries will run on iOS 6 and 10.4, but iOS 8 and/or OSX 10.10 should still be defined at compile time. – jpsim Jun 24 '14 at 03:16
