Question 1

How to stream Markdown from an AI API in an iOS chat app?

Accepted Answer

Use startRealStreaming() to begin, then appendStreamContent() for incoming chunks, and finishStreaming() on completion. Configure typewriterTextMode and streamingHapticFeedbackStyle for smooth effects, as detailed in the real-time streaming section.

Question 2

MarkdownDisplayView vs Down for iOS: which should I use?

Accepted Answer

MarkdownDisplayView is better for real-time streaming and TextKit 2 performance in AI chats, while Down is simpler and supports older iOS versions. Choose based on streaming needs and iOS 15+ targeting.

Question 3

How do I customize syntax highlighting colors to match my app's theme?

Accepted Answer

Modify the syntaxColors and syntaxColorsDark properties in MarkdownConfiguration using the SyntaxHighlightColors struct—set colors for keywords, strings, comments, etc., as shown in the customization examples.

Question 4

Can I use this with SwiftUI or is it UIKit only?

Accepted Answer

It's built on UIKit and TextKit 2, so integration with SwiftUI requires UIViewRepresentable wrappers, adding complexity for SwiftUI-native projects.

Question 5

How does it handle image loading and caching?

Accepted Answer

Images load asynchronously with caching via ImageCacheManager. Use the onImageTap callback for interaction, and ensure network permissions in Info.plist for remote images.

Question 6

What's the performance like when embedding this in table view cells?

Accepted Answer

It supports resetForReuse() for cell recycling and optimized incremental updates, but streaming in cells needs typewriterHeightUpdateInterval configuration to minimize layout jumps during height changes.
