Lesson 3

Lesson 3: Inside Your Project?s Build Settings

Lesson 3, “Inside Your Project’s Build Settings,” covers how Xcode builds its projects. The lesson describes how Xcode organizes a project's build configuration. Then, it shows how these configurations are combined to build an executable and then run that executable. In the final part of this lesson, viewers learn how to break some code into an iOS static library to share the code among multiple projects.

Lesson 7

Lesson 7: General Performance Analysis and Tuning

Lesson 7, “General Performance Analysis and Tuning, helps developers determine why their application doesn’t perform as well as it should. The lesson shows how to use the Time Profiler to understand why the application stops responding and how the application manages threads. Then, the lesson demonstrates how to discover why an application does not scroll at 60fps using the Core Animation Instrument.?

Lesson 8

Lesson 8: Tuning Core Data

Lesson 8, “Tuning Core Data,” covers the probes that analyze Core Data performance to ensure an application remains responsive. Viewers learn how to analyze fetch requests and tune the use of Core Data’s cache so that the application will not hit the disk frequently.. The lesson also shows how to inspect Core Data saves and make sure the application persists the changes to disk when it is absolutely necessary.

Description

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.
