Question 1

How to validate an email address in Swift using Guitar?

Accepted Answer

Question 2

Guitar vs Swift standard library for string manipulation?

Accepted Answer

Guitar extends the standard library with additional utilities like case conversion and padding, while Swift's native APIs are more limited. Choose Guitar if you need these extra functions; otherwise, the standard library might suffice for basic operations to avoid dependencies.

Question 3

Is Guitar compatible with Swift 5.3 and Linux?

Question 5

What are the alternatives to Guitar for Swift string utilities?

Accepted Answer

Alternatives include Voca (a JavaScript library that inspired Guitar) or custom Swift extensions, but Guitar is specifically designed for Swift with cross-platform support. For regex, developers might use NSRegularExpression directly, but Guitar simplifies common patterns.

Question 6

How to install Guitar with Swift Package Manager?

Accepted Answer

Add .Package(url: "https://github.com/ArtSabintsev/Guitar.git", majorVersion: 1) to your dependencies, as specified in the README. This integrates it seamlessly for Swift 5.1+ projects, with older versions requiring branch-specific setups.
