Usage

public enum LCIndicatorType {
    case `default`(count: Int)
    case threeBallsRotation(Color, size: CGFloat)
    case threeBallsTriangle(Color, size: CGFloat)
    case threeBallsBouncing(Color, size: CGFloat, speed: CGFloat)
    case doubleHelix(Color, size: CGFloat, count: Int)
    case arcs(count: Int, lineWidth: CGFloat)
    case rotatingDots(count: Int)
    case flickeringDots(count: Int)
    case scalingDots(count: Int, spacing: Int)
    case audioWaveEqualizer(Color, count: Int)
    case equalizer(count: Int)
    case growingArc(Color, lineWidth: CGFloat)
    case pulseCircle
    case accordion(count: Int)
    case gradient(colors: [Color], lineCap: CGLineCap, lineWidth: CGFloat)
}

• Default type, passing the number of points

LCActivityIndicator(isVisible: $isAnimate, type: .default(count: 8))

• Three points rotating animation

LCActivityIndicator(isVisible: $isAnimate, type: .threeBallsRotation(.black, size: 50))

• Three points forming a triangle rotating animation

LCActivityIndicator(isVisible: $isAnimate, type: .threeBallsTriangle(.black, size: 50))

• Three points bouncing vertically

LCActivityIndicator(isVisible: $isAnimate, type: .threeBallsBouncing(.black, size: 50, speed: 0.5))

• Double helix animation

LCActivityIndicator(isVisible: $isAnimate, type: .doubleHelix(.black, size: 150, count: 10))

• Arc-shaped indicator, creating multiple arcs

LCActivityIndicator(isVisible: $isAnimate, type: .arcs(count: 3, lineWidth: 2))

• Rotating dot indicator, multiple dots rotating

LCActivityIndicator(isVisible: $isAnimate, type: .rotatingDots(count: 5))

• Flickering dot indicator, dots flickering in change

LCActivityIndicator(isVisible: $isAnimate, type: .flickeringDots(count: 8))

• Scaling dot indicator, dots scaling in and out

LCActivityIndicator(isVisible: $isAnimate, type: .scalingDots(count: 3, spacing: 2))

• Music waveform equalizer, dynamic equalizer based on sound frequencies

LCActivityIndicator(isVisible: $isAnimate, type: .audioWaveEqualizer(.black, count: 6))

• Equalizer indicator, showing dynamic bars like audio frequencies

LCActivityIndicator(isVisible: $isAnimate, type: .equalizer(count: 6))

• Growing arc indicator, arcs growing continuously

LCActivityIndicator(isVisible: $isAnimate, type: .growingArc(.black, lineWidth: 10))

• Pulse circle indicator, the circle changes over time

LCActivityIndicator(isVisible: $isAnimate, type: .pulseCircle)

• Accordion indicator, multiple bars bouncing at different heights

LCActivityIndicator(isVisible: $isAnimate, type: .accordion(count: 5))

• Gradient indicator, circular gradient effect

LCActivityIndicator(isVisible: $isAnimate, type: .gradient(colors: [.white, .black], lineCap: .round, lineWidth: 10))
