CocoaPods could not find compatible versions for pod "TrezorCrypto":

[Emin-Emini]

After trying to install this Pod, it's showing this error:

[!] CocoaPods could not find compatible versions for pod "TrezorCrypto":
  In Podfile:
    GoldenKeystore was resolved to 1.0.3, which depends on
      TrezorCrypto (= 0.0.6)

None of your spec sources contain a spec satisfying the dependency: `TrezorCrypto (= 0.0.6)`.

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 * out-of-date source repos which you can update with `pod repo update` or with `pod install --repo-update`.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

Hi,

Probably a little bit too late but the problem is related to TrezorCrypto version 0.0.6.
The latest one is 0.0.9.
To quickly run locally and test, you can: clone GoldenKeystore repository locally; update GoldenKeystore.podspec setting

s.dependency 'TrezorCrypto', '0.0.9'

then update your project Podfile specifying local path

pod 'GoldenKeystore', :path => 'LOCAL_PATH'

Finally execute pod install.

The best thing to do should be a dedicated PR.

Hope it helps.
