You want to add pod 'PayUIndia-DL-SDK', '1.0.0.alpha.1' similar to the following to your Podfile:
target 'MyApp' do
pod 'PayUIndia-DL-SDK', '1.0.0.alpha.1'
end
Then run a pod install inside your terminal, or from CocoaPods.app.
Alternatively to give it a test run, run the command:
pod try PayUIndia-DL-SDK
