Reverse-Engineering iOS Apps: Hacking on Lyft, with Conrad Kramer

About the Speaker: Conrad Kramer Conrad Kramer started developing for iOS after he got involved with the jailbreak scene back in 2010 with his first tweak Graviboard. Since then, he has gotten into regular iOS development and worked on various open source projects in the Cocoa community, like AFOAuth2Client and WFNotificationCenter. Conrad now spends all of his waking hours on Workflow, an automation tool for iOS, where he works on anything from the server backend to building the complex drag and drop interactions. I’m Conrad Kramer, an iOS developer at Workflow, and I will discuss reverse engineering of iOS apps. There are two pain points when you’re doing reverse engineering. Operating tools are difficult because the tools themselves are usually not very well documented and pretty obscure. Sitios Web donde aprender a programar gratis y algunos consejos para no perderte.
