Usage

1. Add an Int to store the current selection
2. Pass your buttons to the AnimatedTabBar using one of 2 initializers. For the first one you can pass any view type:

import AnimatedTabBar

AnimatedTabBar(selectedIndex: $selectedIndex) {
    TabButton1()
    TabButton2()
    TabButton3()
}

For the second one the views must have the same type, or be manually converted to AnyView

AnimatedTabBar(selectedIndex: $selectedIndex, views: [TabButton1(), TabButton2(), TabButton3()])

Required parameters

selectedIndex - binding to the current index
views - buttons to display in the tabbar

Available customizations - modifiers

use the customize closure in the popup modifier:

barColor - Color of the tabbar itself
selectedColor - Selected tab color (use template rendering for this color to be applied properly)
unselectedColor - Unselected tab color
ballColor - Ball indicator color
verticalPadding - Space from the buttons to the bar's top and bottom edges
cornerRadius - The corner radius applied to the tabbar background color
ballAnimation - Animation curve to apply to ball motion, default is .easeOut(duration: 0.6) indentAnimation - Animation curve for growing/shrinking of the indent in the tabbar
buttonsAnimation - Animation curve for applying color to tab buttons
didSelectIndex - Closure which gets called on every tab tap

ballTrajectory - Options for ball indicator animation paths:

• parabolic - Jump to the selected button following a parabolic arc
• teleport - Disappear and quickly re-appear above selected tab
• straight - Slide to the selected tab

Built-in animatable tab buttons

By default tabs only have a simple color animation, but you can customize that. This library has two built-in button types you can use out-of-the-box: DropletButton and WiggleButton, and a super custom ColorButton type in the Example project. Please feel free to use them in your projects or build your own buttons on top of them.
