View my outdated pods (which includes Hero) to update to Hero 1.5.0
That Hero 1.5.0 would be found
Hero 1.5.0 was not found
I believe that while the podspec was updated, the podspec was not released with pod trunk push NAME.podspec
I use this, successfully installed Hero 1.5.0
pod 'Hero', :git => 'https://github.com/HeroTransitions/Hero.git'
Looks like it wasn't pushed, see specs, will look into it.

Version 1.5.0 has been released, thanks for the heads up guys.
