Rating Bar - SwiftUI Component

Developed by: Sameer Mungole

Available on: iOS 17+ & macOS 14+

An interactive rating bar that utilizes drag gestures and animations to let users leave a rating for a product.

How to Install:

• In the toolbar, click on File → Swift Packages > Add Package...
• In the modal, enter the GitHub URL https://github.com/hauntarl/RatingBar.git in the input field.

This view enables two-way interactions:

1. Control the rating using drag gestures
2. Control the rating by externally managing the rating property

The following example shows how to use the RatingBar:

RatingBar(
   rating: $rating,
   shape: Capsule(),
   fillColor: .accentColor,
   backgroundColor: .primary.opacity(0.2)
)

The following example shows two-way interactions using the RatingBar:

VStack {
   RatingBar(
       rating: $rating,
       width: 300,
       height: 50,
       parts: 5,
       spacing: 5,
       shape: Capsule(),
       fillColor: .yellow,
       backgroundColor: .primary.opacity(0.2),
       animation: .smooth
   )

   TextField("Rating", text: Binding(get: {
       String(format: "%.2f", rating)
   }, set: { newValue in
       rating = Double(newValue) ?? .zero
   }))
}

The view makes sure that the rating ranges in [0, parts], it basically won't let the user feed erroneous values to the rating property externally.

Note 1: Sometimes the shapes might get clipped when interacting, it can be easily fixed by providing more height to the view.

Note 2: You might receive

onChange(of: Double) action tried to update multiple times per frame.

message in the console, it usually comes when the animation duration is longer, but it hasn't affected the performance of the application or resulted in any unintended crashes.

This package also contains custom shapes like RatingBarTriangle, and RatingBarRoundedStar under the CustomShapes.swift file. They are publicly accessible for you to use, I will keep adding more custom shapes with time.

I appreciate your time and interest in my package, as this is my first package in SwiftUI, I probably didn't adhere to the industry standards. I would really appreciate your feedback regarding any changes I need to make or bugs I need to fix!
