Cocoapods subspec issue: None of your spec sources contain a spec satisfying the dependency

I modified a repo on Github to integrate a swift version of my library.

https://github.com/iDevelopper/PBRevealViewController

However when in a new project I try to pod install I get the error:

[!] Unable to satisfy the following requirements:

PBRevealViewController/Swift (= 1.2.3) required by Podfile

None of your spec sources contain a spec satisfying the dependency: PBRevealViewController/Swift (= 1.2.3).

You have either: * out-of-date source repos which you can update with pod repo update or with pod install --repo-update.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.

Some helps are welcome!
