CocoaPods only supports Swift on OS X 10.9 and newer, and iOS 8 and newer.

Here's why:

  • Swift is supported on OS X 10.9 / iOS 7 and newer, as stated by Apple numerous times.

  • There is no support for building static archives with Swift.

  • Dynamic frameworks are supported on all versions of OS X.

  • Dynamic frameworks are unsupported on iOS versions prior to 8:

    ld: warning: embedded dylibs/frameworks only run on iOS 8 or later.

From this we can conclude that it is not possible to support Swift on any platforms earlier than OS X 10.9 and iOS 8.

To use Swift libraries on apps that support iOS 7, you must manually copy the files into your application project.
