Mastering Swift 2 Programming (Video 42)

This video tutorial explores the use of Xcode's address sanitizer for debugging memory issues in clang-based languages. It covers setting up a memory problem, enabling address sanitization in Xcode, and analyzing memory issues using the tool. The tutorial also highlights the benefits of address sanitization when working with Objective-C or C, and provides a preview of the next video on debugging techniques using assertions.

What is the primary purpose of the Address Sanitizer?

• To compile code faster

• To enhance user interface design

• To detect memory issues like buffer overflows

• To optimize code performance

Which file type is NOT mentioned as necessary for setting up Address Sanitizer?

• Java file

• Bridging header file

• C file

• Header file

What should you do after creating a bridging header file?

• Drag the bridging header into the build settings

• Compile the project

• Run the application

• Delete the bridging header

What additional information does Address Sanitizer provide when a memory issue is detected?

• A list of all files in the project

• A list of all functions in the code

• A detailed stack trace

• A summary of all variables

How can you view which portions of memory are valid or invalid?

• By clicking on the address in the memory view

• By checking the console output

• By running the application in release mode

• By using a third-party tool
