Question 1

How do I install the Regex package in Xcode?

Accepted Answer

Add it via Xcode's package manager by entering the GitHub URL, or update your Package.swift file with the dependency as shown in the README—it's straightforward for iOS/macOS projects.

Question 2

What's better: Regex or using NSRegularExpression directly?

Accepted Answer

Regex offers a cleaner, more Swifty API with less boilerplate, but if you need fine-grained control or avoid dependencies, raw NSRegularExpression might be preferable for simple cases.

Question 3

Can Regex handle complex patterns with comments and whitespace?

Accepted Answer

Yes, it supports multiline patterns with comments using the `.allowCommentsAndWhitespace` option, demonstrated in the README with raw strings for better readability.

Question 4

How to extract named capture groups in Swift with Regex?

Accepted Answer

Use the `group(named:)` method on match objects, e.g., `regex.firstMatch(in: text)?.group(named: "word")?.value` to retrieve values from named groups efficiently.

Question 5

Is Regex compatible with Swift on Linux or server-side projects?

Accepted Answer

It depends on Foundation's NSRegularExpression implementation on Linux, which may have limitations; test thoroughly as it's primarily designed for Apple platforms.

Question 6

How to replace all matches in a string using Regex?

Accepted Answer

Use the `replacingAllMatches(of:with:)` extension on String, as shown in the README, which simplifies bulk replacements without manual iteration.
