There are four ways to use BSZoomGridScrollView in your project:
CocoaPods is a dependency manager for Objective-C, which automates and simplifies the process of using 3rd-party libraries in your projects. See the Get Started section for more details.
First,
pod 'BSZoomGridScrollView'
then in your root project,
pod install
Swift Package Manager (SwiftPM) is a tool for managing the distribution of Swift code as well as C-family dependency. From Xcode 11, SwiftPM got natively integrated with Xcode.
BSZoomGridScrollView support SwiftPM from version 5.1.0. To use SwiftPM, you should use Xcode 11 to open your project. Click File
-> Swift Packages
-> Add Package Dependency
, enter BSZoomGridScrollView repo's URL. Or you can login Xcode with your GitHub account and just type BSZoomGridScrollView
to search.
After select the package, you can choose the dependency type (tagged version, branch or commit). Then Xcode will setup all the stuff for you.
If you're a framework author and use BSZoomGridScrollView as a dependency, update your Package.swift
file:
let package = Package(
dependencies: [
.package(url: "https://github.com/boraseoksoon/BSZoomGridScrollView", from: "0.1.1")
],
// ...
)
It was done for my fun.
