SwizzleSwift

Who said that method swizzling needs to look ugly? SwizzleSwift is a little wrapper that lets you swizzle selectors just one clean and elegant API.

SwizzleSwift: Swizzle selectors with just one clean and elegant API

Version License Platform

Installation

Pods

pod 'SwizzleSwift'

Swift package manager

From Xcode, select File → Swift Packages → Add Package Dependency → Select your project → Search SwizzleSwift

Usage example

Swizzle(<#AType.Self#>) {
	<#OriginalSelector#> <-> <#SwizzledSelector#>
}

Given the following controller

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        print(#function)
    }
    
    override func viewWillAppear(_ animated: Bool) {
        super.viewWillAppear(animated)
        print(#function)
    }

}

extension UIViewController {

    @objc private func myViewDidLoad() {
        print(#function)
        myViewDidLoad()
    }
    
    @objc private func myViewWillAppear(_ animated: Bool) {
        print(#function)
        myViewWillAppear(animated)
    }
    
}

Swizzling the methods like this

extension UIViewController {

    @objc static func methodSwizzling() -> Void {
        Swizzle(ViewController.self) {
            #selector(viewDidLoad) <-> #selector(myViewDidLoad)
            #selector(viewWillAppear(_:)) <-> #selector(myViewWillAppear(_:))
        }
    }
    
}

Will produce the following output

myViewDidLoad()
viewDidLoad()
myViewWillAppear(_:)
viewWillAppear(_:)
