Chip Stack Visualizer - iPad

Overview

An innovative iPad application that provides real-time visual representation of casino chip stacks with intuitive counting controls. Designed specifically for casino floor operations, this app displays eight different chip denominations as vertical stacks that grow and shrink dynamically as chips are added or removed. Features include long-press rapid counting, percentage capacity indicators, and a visually appealing interface optimized for iPad's larger screen with horizontal scrolling support.

Features

• 8 Chip Denominations: Track Purple (120), Blue (90), Green (60), Red (180), Orange (150), Pink (30), Gray (75), and Cyan (110) chips
• Visual Stack Representation: Real-time vertical stacking animation showing chip accumulation
• Long-Press Rapid Count: Hold increment/decrement buttons for fast continuous counting (100 chips/second)
• Percentage Display: Shows stack capacity as percentage of maximum (200 chips per frame)
• Horizontal Scrolling: Smooth horizontal scroll view for easy access to all chip types
• Color-Coded Design: Each chip type has unique color matching casino standards
• Tap Counting: Single tap for precise one-chip adjustments
• Custom Background: Decorative background image for enhanced visual appeal
• Shadow Effects: 3D card shadows for depth and professional appearance
• Disabled State Handling: Buttons intelligently disable at min (0) and max (200) limits

Technical Stack

• Language: Swift 5.9+
• Framework: SwiftUI
• Platform: iPadOS 15.0+
• Architecture: Component-based view composition
• UI Components: ScrollView, VStack, HStack, ForEach
• Gestures: LongPressGesture, DragGesture, simultaneousGesture
• Animation: Implicit animations for stack growth

Key Learning Concepts

Advanced Gesture Recognition

• LongPressGesture for hold-to-increment functionality
• DragGesture for release detection
• simultaneousGesture modifier for gesture composition
• Minimum duration configuration for long press
• Gesture state management and cleanup

Timer-Based Rapid Counting

• Timer.scheduledTimer for repeating actions
• High-frequency timers (0.01s intervals) for smooth counting
• Timer invalidation and memory management
• Start/stop timer control methods
• Preventing timer overlap with cleanup

Dynamic Visual Feedback

• ForEach with range-based iteration for stack rendering
• Rectangle shapes for chip visualization
• Dynamic height calculation based on count
• Color opacity for visual hierarchy
• Frame clipping for contained stacks

State Management & UI Updates

• @State for local component state
• Real-time UI updates from state changes
• Computed property formatting for percentages
• Conditional rendering based on count
• Button state management (enabled/disabled)

ScrollView & Layout

• Horizontal ScrollView configuration
• HStack alignment for bottom-aligned cards
• Spacing and padding optimization for iPad
• Background image integration
• Frame sizing for consistent card dimensions

Code Highlights

Long-Press Rapid Counting

Sophisticated gesture handling for fast chip counting:

Button {
    increment()
} label: {
    Image(systemName: "plus.circle.fill")
        .font(.largeTitle)
}
.foregroundColor(.green)
.disabled(chipCount >= maxChipsInFrame)
.simultaneousGesture(
    LongPressGesture(minimumDuration: 0.3)
        .onEnded { _ in startIncrementing() }
)
.simultaneousGesture(
    DragGesture(minimumDistance: 0)
        .onEnded { _ in stopIncrementing() }
)

func startIncrementing() {
    stopIncrementing() // Prevent multiple timers
    incrementTimer = Timer.scheduledTimer(withTimeInterval: 0.01, repeats: true) { _ in
        increment()
    }
}

func stopIncrementing() {
    incrementTimer?.invalidate()
    incrementTimer = nil
}

Dynamic Chip Stack Visualization

Real-time visual representation of chip counts:

VStack(spacing: 0) {
    Spacer()
    if chipCount > 0 {
        ForEach(0..<chipCount, id: \.self) { _ in
            ChipVisual(color: chipColor)
        }
    }
}
.frame(width: chipStackWidth, height: chipStackHeight)
.background(chipColor.opacity(0.2))
.cornerRadius(8)
.clipped() // Prevent overflow beyond container

struct ChipVisual: View {
    var color: Color
    var body: some View {
        Rectangle()
            .fill(color)
            .frame(height: 0.44) // Thin chip representation
    }
}

Percentage Capacity Display

Clear visual feedback on stack capacity:

Text("\(chipCount)")
    .font(.title2)
    .fontWeight(.medium)

Text("\(String(format: "%.0f%% full", (Double(chipCount) / Double(maxChipsInFrame)) * 100))")

Horizontal Scrolling Container

iPad-optimized layout with smooth scrolling:

ScrollView(.horizontal, showsIndicators: false) {
    HStack(alignment: .bottom, spacing: 16) {
        ForEach(0..<chipConfigs.count, id: \.self) { index in
            let config = chipConfigs[index]
            ChipCardView(chipColor: config.0, chipCount: config.1)
        }
    }
    .padding(.horizontal)
}
