coco pod MBProgressHUD+DK (~> 1.0.8)...

!] Unable to satisfy the following requirements:

- `MBProgressHUD+DK (~> 1.0.8)` required by `Podfile`

- `MBProgressHUD+DK (= 1.0.8)` required by `Podfile.lock`

None of your spec sources contain a spec satisfying the dependencies: `MBProgressHUD+DK (~> 1.0.8), MBProgressHUD+DK (= 1.0.8)`.

You have either:

* out-of-date source repos which you can update with `pod repo update`.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.
