Last year, Apple introduced Passbook with their release of iOS 6. This application is designed to store movie tickets, gift cards, discount codes, and airline boarding passes, letting you generate passes to buy coffee, redeem retailer coupons, or check in for flights. While Passbook allows developers to create highly innovative experience without having to write any Objective-C, it can also be challenging to figure out how to get passes signed correctly and understand notification service endpoints. Luckily, as a Ruby developer we have the passbook-ios gem to make our job easier. In this session, we will explore the basics of Passbook development using passbook-ios and discuss some of the strategies for developing Passbook-enabled apps successfully based on real world experience.
