Aspect is a lightweight, pure-Swift library for for aspect oriented programming. This project is heavily inspired by the popular Aspects. It provides you a chance to use a pure-Swift alternative in your next app.

Features

• Hook object selector
• Hook different classes selector in the same hierarchy
• Hook class and static selector
• Provide more friendly Swift interfaces

Usage

Hook object selector with OC block

public class Test: NSObject {

    @objc dynamic func test(id: Int, name: String) {

    }

    @objc dynamic static func classSelector(id: Int, name: String) {

    }
}

let test = Test()

let wrappedBlock: @convention(block) (AspectInfo, Int, String) -> Void = { aspectInfo, id, name in

}
let block: AnyObject = unsafeBitCast(wrappedBlock, to: AnyObject.self)
test.hook(selector: #selector(Test.test(id:name:)), strategy: .before, block: )

Hook object selector with Swift block

let test = Test()

_ = try? test.hook(selector: #selector(Test.test(id:name:)), strategy: .before) { (_, id: Int, name: String) in

}

Hook class instance selector with Swift block

_ = try? Test.hook(selector: #selector(Test.test(id:name:)), strategy: .before) { (_, id: Int, name: String) in

}

Hook class class and static selector with Swift block

_ = try? Test.hook(selector: #selector(Test.classSelector(id:name:)), strategy: .before) { (_, id: Int, name: String) in

}
