Objective C vs SWIFT Programming Languages

The video tutorial compares Objective-C and Swift, two programming languages used for iOS and Mac applications. Objective-C, a combination of Smalltalk and C, has been around since the 1990s, while Swift was introduced in 2014 as a modern, fast, and safe alternative. The tutorial covers various aspects such as user interface design, performance, safety, toolkits, community support, long-term perspective, code complexity, and memory management. Swift is highlighted for its simplicity, open-source nature, and better performance, while Objective-C is noted for its extensive history and existing toolkits.

What is one of the main reasons for comparing Objective-C and Swift?

• Swift is a direct descendant of Objective-C.

• Objective-C is newer than Swift.

• They are both used for Android development.

• They are both used to develop native iOS applications.

Which iOS version is the minimum requirement for Swift?

• iOS 7

• iOS 6

• iOS 8

• iOS 5

Why is Swift considered faster than Objective-C?

• It supports older iOS versions.

• It performs type checking at compile time.

• It is not open-source.

• It has a more complex syntax.

What is a key advantage of Swift being open-source?

• It is only supported by Apple.

• It has fewer tools available.

• It allows for more community support.

• It is harder to learn.

How does Swift handle memory management differently from Objective-C?

• Swift does not support ARC.

• Swift supports ARC for all APIs.

• Objective-C supports ARC for all APIs.

• Swift uses manual memory management.

What feature of Swift helps avoid common causes of crashing?

• String interpolation

• Manual memory management

• Null pointers

• Complex syntax

Why might companies consider converting Objective-C code to Swift?

• Swift is less concise.

• Objective-C is more modern.

• Objective-C is open-source.

• Swift offers better performance and safety.
