• [x] Provide a more friendly Swift interface

Usage

Hook object selector with OC block

public class Test: NSObject {
   @objc dynamic func test(id: Int, name: String) {
        print(id)
        print(name)
    }
}

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

test.hook(selector: #selector(Test.test(id:name:)), strategy: .before) { (aspectInfo: AspectInfo, id: Int, name: String) in

}
