LiveLessons - Xcode and Instruments Fundamentals
3+ Hours of Video Instruction
Xcode and Instruments Fundamentals LiveLessons covers how to develop and debug applications with the Xcode IDE and how to use Instruments to perform sophisticated debugging and performance analysis.
Brandon Alexander, developer and author, covers how to use the iOS development toolkit. The first four lessons cover Xcode by showing viewers how to navigate the basic interface, create a new project and use various editors, understand how Xcode organizes the build settings, debug their application with LLDB, and customize Xcode for their workflow. Lessons 5-10 focus on Instruments by showing viewers how to navigate the interface and profile their application, analyze memory leaks and break retain cycles, analyze general performance and make the application responsive, analyze Core Data performance, analyze power consumption of the application, and use Instruments to drive the application.
