A customizable range slider UI component for iOS built with Swift, supporting IBDesignable and target-action patterns.
RangeSlider is a Swift library that provides a customizable range slider UI component for iOS applications. It allows users to select a numeric range using two draggable thumbs, with support for visual customization and real-time value change notifications. It solves the need for a reusable, well-designed range picker in native iOS interfaces.
iOS developers building apps that require range selection features, such as e-commerce filters, settings panels, or data visualization tools.
Developers choose RangeSlider for its simplicity, Interface Builder support, and easy integration via CocoaPods or Swift Package Manager, avoiding the need to build a custom slider from scratch.

The component is IBDesignable, allowing visual customization and preview directly in Interface Builder without running the app.
Uses the target-action pattern with .valueChanged events, making it simple to respond to slider updates in real-time, as demonstrated in the README code example.
Offers properties like trackTintColor, thumbTintColor, and curvaceousness to adjust colors and shapes from square to circular, providing flexibility in design.
Provides clear properties for minimumValue, maximumValue, lowerValue, and upperValue, enabling easy access and manipulation of range values.
Only supports two thumbs, making it unsuitable for applications that require selecting multiple disjoint ranges or more complex slider interactions.
The README doesn't mention support for step values or snapping, which could be a limitation for precise control in settings like currency or time increments.
Designed exclusively for iOS, so it can't be used in macOS, watchOS, or cross-platform projects without significant additional development effort.
