I am displaying a multiline text in a Text component. Ideally, I'd prefer some lines to be shown bold, like they are headers. I made a search and only found advice which was rather old. So far, I will probably go the RichText custom component way (https://github.com/NuPlay/RichText).

However, displaying rich text is such a basic thing, and it existed in UIKit. So I am thinking maybe in the most up-to-date version of SwiftUI this was already made possible, and I simply was unable to find that?

You may want to look at the inline text markdown options that were introduced in iOS15.

Adding URLs to Forum Posts

You can add Markdown links to your Hacking With Swift forum posts! This allows you to hide the full URL, and provide an easy-to-read description.

Whilst composing your response, place the link's description inside a pair of square brackets:

// The description is inside the square brackets...
See -> [Enable Markdown in XCode]

Immediately after the square brackets, embed the URL inside of parenthesis:

// The URL is inside the parenthesis right after the description...
See -> [Enable Markdown in XCode](https://www.hackingwithswift.com/quick-start/swiftui/how-to-render-markdown-content-in-text)

When rendered in Markdown, you see the description, but the URL is hidden.
You get a simple, cleaner link for your readers.
