Question 1

How to use GRMustache.swift with SwiftUI for dynamic content?

Accepted Answer

Render templates into strings using Template.render(), then display them in SwiftUI Text views. Load templates from bundle resources or strings, and update the data model to trigger re-renders as needed.

Question 2

GRMustache.swift vs Stencil: which is better for Swift projects?

Accepted Answer

GRMustache.swift is Mustache-compliant with pure Swift integration, while Stencil uses a Django-like syntax. Choose based on preference for Mustache standards vs. more logic-oriented syntax and community size.

Question 3

How to register a custom filter in GRMustache.swift?

Accepted Answer

Define a filter using the Filter() function, then register it with template.register(filter, forKey: "key"). For example, create an uppercase filter that transforms strings, as shown in the README's filter section.

Question 4

Does GRMustache.swift support async rendering for performance?

Accepted Answer

No, the library does not explicitly support async rendering; rendering is synchronous. For heavy templates, manually offload work to background threads to avoid blocking the main thread.

Question 5

Can GRMustache.swift load templates from a remote URL?

Accepted Answer

Yes, use Template(URL:) to load templates from URLs, enabling dynamic updates from web sources. This is part of the multiple template sources feature documented in the README.

Question 6

What's the best way to handle errors in GRMustache.swift templates?

Accepted Answer

Use do-catch blocks and check for MustacheError types, which provide detailed info like line numbers, error kinds, and template IDs for debugging, as explained in the Errors section.
