Question 1

How to add an animated gradient background in SwiftUI with Pastel?

Accepted Answer

Use the .pastelBackground modifier with a preset gradient like .instagram or custom colors. For example, Text("Hello").pastelBackground(.instagram) applies the animation directly, as shown in the README SwiftUI examples.

Question 2

Pastel vs native SwiftUI gradients: which is better for animations?

Accepted Answer

Pastel is optimized for smooth, pre-configured animations with minimal code, offering preset gradients and shared states. Native SwiftUI gradients require manual animation setup, making Pastel easier for Instagram-style effects but less flexible for advanced customization.

Question 3

Can I sync gradient animations on multiple views in UIKit?

Accepted Answer

Yes, use PastelAnimationState to coordinate animations. Create a state with colors and duration, then assign it to multiple PastelView instances, as demonstrated in the README UIKit shared state example.

Question 4

How to change the animation speed in Pastel?

Accepted Answer

Set the duration parameter when defining the gradient. In SwiftUI, use pastelBackground(colors:duration:), and in UIKit, adjust the animationDuration property on PastelView, both detailed in the README code snippets.

Question 5

Is Pastel compatible with iOS 15 or lower?

Accepted Answer

No, Pastel requires iOS 16.0 or higher, as specified in the README requirements. For older iOS versions, you'll need to use alternative libraries or native implementations.

Question 6

How to create a custom gradient with specific colors in Pastel?

Accepted Answer

Define an array of UIColor objects and pass them to the gradient function. For instance, in SwiftUI, use pastelBackground(colors: [.red, .blue], duration: 2.0), similar to the custom color example provided.
