swift 4? about bubbletransition HOT 6 CLOSED

[!] CocoaPods could not find compatible versions for pod "BubbleTransition":
  In Podfile:
    BubbleTransition (~> 3.0.0)

None of your spec sources contain a spec satisfying the dependency: `BubbleTransition (~> 3.0.0)`.

You have either:
 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.
 * mistyped the name or version.
 * not added the source repo that hosts the Podspec to your Podfile.

Note: as of CocoaPods 1.0, `pod repo update` does not happen on `pod install` by default.
