How do I create a custom animator in RHPlaceholder?

Conform to the LayerAnimating protocol as mentioned in the README, then pass your custom Animator class as a parameter to the Placeholder initializer. This allows you to define unique animation behaviors beyond the predefined gradient or blink effects.

RHPlaceholder vs SkeletonView: which is better for iOS loading?

RHPlaceholder is focused on gradient-based animations similar to Instagram, while SkeletonView offers skeleton screen effects for content blocking. Choose RHPlaceholder for trendy, visual placeholders; SkeletonView for more subtle, content-aware loading states. RHPlaceholder is simpler for basic animations but has fewer community resources.

Can I use RHPlaceholder with SwiftUI?

The README doesn't mention SwiftUI compatibility, and since it's designed for UIKit and storyboards, direct integration with SwiftUI may require additional bridging or wrappers. Check the demo project for UIKit-based examples only.

How to handle errors or retries with RHPlaceholder animations?

The library provides basic control with `startAnimation()` and `remove()` methods, but error handling or retry logic must be implemented manually in your data fetching code, as it's not built into the placeholder animations.

Does RHPlaceholder work with CocoaPods and Carthage?

Yes, the README includes installation instructions for both CocoaPods (pod 'RHPlaceholder') and Carthage (adding the GitHub repo to Cartfile), making it flexible for different dependency management setups in iOS projects.

What are the performance costs of using RHPlaceholder?

While not detailed in the README, gradient animations can be more resource-intensive than native UIActivityIndicatorView. For performance-sensitive apps, test on target devices to ensure smooth frame rates, especially with multiple animated views.

Pros & Cons

Pros

Simple Setup

Integration takes only a few lines of code, as shown in the README with examples like `placeholderMarker.register(viewElements)` and methods like `startAnimation()` for quick implementation.

Varied Animations

Offers multiple predefined animators such as InstaLayerAnimatorGradient and RainbowAnimatorGradient, with visual examples provided in GIFs for easy selection.

Storyboard Compatibility

Designed to work seamlessly with storyboard-based view controllers, making it accessible for developers using Interface Builder without code-heavy setups.

Extensible Design

Allows creation of custom animators by conforming to the LayerAnimating protocol, enabling unique visual effects beyond the built-in options.

Cons

Unstable API

The README's Swift support table explicitly states that versions are 'very early' and 'API may change', posing a risk for production apps with breaking updates.

Limited Documentation

Beyond basic usage examples, there's no extensive guide or advanced tutorials, which could hinder complex customizations or troubleshooting.

iOS-Only Lock-in

Specifically built for iOS, it's not suitable for cross-platform projects targeting Android, web, or other environments, limiting its versatility.
