AAA

An Any Accessory.

An Any Accessory?

Well.. it sounds great. So, what is it?

You probably encountered at least once the situation that upcasted [Any], [AnyHashable: Any] or anything as Any. If so, you wrote as follows:

func tion(_ anAny: Any) -> Int {
    var anArray: [Int]?
    var aDictionary: [String: Any]?
    var result = 0
    if anAny is [Int] {
        anArray = anAny as! [Int]
    }
    else if anAny is [String: Int] {
        aDictionary = anAny as! [String: Int]
    }
    if let anArray = anArray {
        result = ((anArray[3] as? [Int])?[9] as? [Int])?[27]? ?? 0
    }
    else if let aDictionary = aDictionary {
        result = (aDictionary["3"] as? [String: [String: Int]])?["9"]?["27"] ?? 0
    }
    return result
}

No, stop! Please have mercy on me!

Okay. I'll show some mercy to you.

• Package.swift (Using Swift Package Manager)

import PackageDescription

let package = Package(
    name: "AWESOME_APP",
    dependencies: [
        .Package(url: "https://github.com/minacle/AAA.git", majorVersion: 1),
    ]
)

• Cartfile (Using Carthage)

github "minacle/AAA" ~> 1.0

• Podfile (Using CocoaPods)

target 'AWESOME_APP' do
  use_frameworks!
  pod 'AAA', '~> 1.0'
end

...Now, we have AAA. Let's try it!

import AAA

func tion(_ anAny: Any) -> Int {
    let a = AAA(anAny)
    return (a[3][9][27][] ?? a["3"]["9"]["27"][]) as? Int ?? 0
}

Wait, what? Are these really same code? What a beautiful!

So, how to use it?

It's super simple.

1. Just wrap anything with AAA.
2. Explore with index or key.
3. [] to get a copy of the thing!

One more thing. It never throws error!

• If index or key was wrong, it returns AAA which contains nil.
• If so, [] returns nil.
