Installation

1. Clone or download the repo
2. Open CodeGenerator.xcodeproj
3. Enable target signing for both the Application and the Source Code Extension using your own developer ID
4. Select the application target and then Product > Archive
5. Export the archive as a macOS App
6. Run the app, then quit (Don't delete the app, put it in a convenient folder)
7. Go to System Preferences -> Extensions -> Xcode Source Editor and enable the CodeGenerator extension
8. The menu-item should now be available from Xcode's Editor menu

Uninstallation

1. Remove the App, restart Xcode.

CodeGenerator

CodeGenerator is a Xcode extension for swift code generation.

Generating mock

Example:

protocol Pokemon {
    var height: Double! { get set }
    var canEvolve: Bool! { get }

    func eat(food: String)

    func drink(_ water: String)

    func isFlying() -> Bool

    func evolve(successHandler: @escaping (String) -> Void, failureHandler: (String?) -> String?)
}

class PokemonMock: Pokemon {
    var height: Double!
    var canEvolve: Bool!

    var eatFood: String?
    var drinkWater: String?
    var evolveShouldCallSuccessHandler = true
    var evolveSuccessHandlerParam0: String!
    var evolveShouldCallFailureHandler = true
    var evolveFailureHandlerParam0: String!
    var evolveFailureHandlerDidReturn: String?

    var eatFoodWasCalled: Bool?
    var drinkWasCalled: Bool?
    var isFlyingWasCalled: Bool?
    var evolveSuccessHandlerWasCalled: Bool?

    var isFlyingShouldReturn: Bool!

    func eat(food: String) {
        eatFood = food
        eatFoodWasCalled = true
    }

    func drink(_ water: String) {
        drinkWater = water
        drinkWasCalled = true
    }

    func isFlying() -> Bool {
        isFlyingWasCalled = true
        return isFlyingShouldReturn
    }

    func evolve(successHandler: @escaping (String) -> Void, failureHandler: (String?) -> String?) {
        if evolveShouldCallSuccessHandler {
            successHandler(evolveSuccessHandlerParam0)
        }
        if evolveShouldCallFailureHandler {
            evolveFailureHandlerDidReturn = failureHandler(evolveFailureHandlerParam0)
        }
        evolveSuccessHandlerWasCalled = true
    }

}

Generating Equatable

Example:

class EquatableClazz {
    var var0: Int!
    let var1: String
    var var2: Bool?
}

extension EquatableClazz: Equatable {
    static func ==(lhs: EquatableClazz, rhs: EquatableClazz) -> Bool {
        return lhs.var0 == rhs.var0 && lhs.var1 == rhs.var1 && lhs.var2 == rhs.var2
    }
}

if you don't want to use all the vars for the Equatable, just select the vars you want and click Generate... -> Equatable

Generating Hashable

Example:

class EquatableClazz {
    var var0: Int!
    let var1: String
    var var2: Bool?
}

extension EquatableClazz: Hashable {
    static func ==(lhs: EquatableClazz, rhs: EquatableClazz) -> Bool {
        return lhs.var0 == rhs.var0 && lhs.var1 == rhs.var1 && lhs.var2 == rhs.var2
    }

    var hashValue: Int {
        var hashValue = 1
        let hashableVars: [AnyHashable?] = [var0, var1, var2]
        hashableVars.forEach {
            hashValue = 31 * hashValue + ($0?.hashValue ?? 0)
        }
        return hashValue
    }
}

Generating Init

Example:

class EquatableClazz {
    var var0: Int!
    let var1: String
    var var2: Bool?

    init(var0: Int?, var1: String, var2: Bool?) {
        self.var0 = var0
        self.var1 = var1
        self.var2 = var2
    }


}

Generating NSCoding

Example:

class EquatableClazz {
    var var0: Int
    let var1: String
    var var2: Bool?

    required init?(coder aDecoder: NSCoder) {
        guard let var1 = aDecoder.decodeObject(forKey: "var1") as? String else { return nil }
        var0 = aDecoder.decodeInteger(forKey: "var0")
        self.var1 = var1
        if aDecoder.containsValue(forKey: "var2") {
            var2 = aDecoder.decodeBool(forKey: "var2")
        }
    }

    func encode(with aCoder: NSCoder) {
        aCoder.encode(var0, forKey: "var0")
        aCoder.encode(var1, forKey: "var1")
        aCoder.encode(var2, forKey: "var2")
    }
}
