Animated Tab Bar

AnimatedTabBar is a tabbar with number of preset animations written in pure SwiftUI

Usage

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

import AnimatedTabBar

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

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

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

Required parameters

selectedIndex – binding to current index views – buttons to display in a tabbar

Available customizations – modifiers

use customize closure in 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 buttons to bar’s top and bottom edges cornerRadius – Applied to tabbar background color ballAnimation – Default is .easeOut(duration: 0.6): Animation curve to apply to ball motion indentAnimation – Animation curve for growing/shrinking of the indent in the tabbar buttonsAnimation – Animation curve for applying color to tab buttons

ballTrajectory – Options for ball indicator animation paths:

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

Built-in animatable tab buttons

By default tabs only have a simple animation of color, 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 Example project. Please feel free to use them in your projects or build your own buttons on top of them.
