Installation
ExpandedTabBar doesn't contain any external dependencies.
These are currently the supported intllation options:
CocoaPods
To integrate ExpandedTabBar into your Xcode project using CocoaPods, specify it in your Podfile:
use_frameworks!
target '<Your Target Name>' do
pod 'ExpandedTabBar'
endSwift Package Manager
The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the swift compiler. It is in early development, but appstore-card-transition does support its use on supported platforms.
Once you have your Swift package set up, adding ExpandedTabBar as a dependency is as easy as adding it to the dependencies value of your Package.swift.

.package(url: "https://github.com/yervandsar/ExpandedTabBar", from: "3.0.1")
