Mastering Swift 2 Programming (Video 28)

This video tutorial explores how to work with C++ in Swift projects without direct interoperability. It discusses the challenges of integrating C++ due to its complexity and presents two approaches: using C++ code in an Objective-C++ file and wrapping C++ code in C. The tutorial provides a step-by-step guide to creating an Xcode project, implementing C++ code, and running the application. It concludes with a preview of the next video on using CocoaPods for third-party libraries.

Why is direct interoperability between Swift and C++ challenging?

• Swift does not support any other languages.

• C++ is a simple language.

• C++ is a complex language.

• Swift is not designed for interoperability.

What is one method to use C++ code in Swift projects?

• Ignoring C++ code altogether.

• Directly writing C++ in Swift files.

• Using C++ code inside an Objective-C++ file.

• Converting C++ code to Java.

What is the first step in integrating C++ code using Objective-C++ in an Xcode project?

• Add a new Objective-C file.

• Create a new Swift file.

• Install a C++ compiler.

• Write C++ code directly in Swift.

What does renaming the file from .M to .MM achieve?

• It deletes the file.

• It compiles the file automatically.

• It turns the file into an Objective-C++ document.

• It converts the file to a Swift document.

What is the final step to see the C++ code output in the console?

• Compile the code manually.

• Delete the bridging header.

• Run the application without any changes.

• Build and run the application.
