Unable to mock a protocol with methods that differ in parameter type - Error: "Invalid redeclaration"

[r3econ]

I am unable to mock a protocol with methods that differ in parameter type. For example:

// sourcery: AutoMockable
public protocol ProtocolA {
    func doSomething(_ data: Int) -> [String]
    func doSomething(_ data: String) -> [String]
}

The generated mock is invalid and can't be compiled. The compiler shows errors like Invalid redeclaration of 'doSomethingCallsCount'. The mock:

// Generated using Sourcery 2.1.2 — https://github.com/krzysztofzablocki/Sourcery
// DO NOT EDIT
import Foundation
import Core

// swiftlint:disable all
open class AMock: ProtocolA {

    public init() {}

    // MARK: - doSomething

    public var doSomethingCallsCount = 0
    public var doSomethingCalled: Bool {
        return doSomethingCallsCount > 0
    }
    public var doSomethingReceivedData: Int?
    public var doSomethingReceivedInvocations: [Int] = []
    public var doSomethingReturnValue: [String]!
    public var doSomethingClosure: ((Int) -> [String])?

    public func doSomething(_ data: Int) -> [String] {
        doSomethingCallsCount += 1
        doSomethingReceivedData = data
        doSomethingReceivedInvocations.append(data)
        if let doSomethingClosure {
            return doSomethingClosure(data)
        } else {
            return doSomethingReturnValue
        }
    }

    // MARK: - doSomething

    public var doSomethingCallsCount = 0
    public var doSomethingCalled: Bool {
        return doSomethingCallsCount > 0
    }
    public var doSomethingReceivedData: String?
    public var doSomethingReceivedInvocations: [String] = []
    public var doSomethingReturnValue: [String]!
    public var doSomethingClosure: ((String) -> [String])?

    public func doSomething(_ data: String) -> [String] {
        doSomethingCallsCount += 1
        doSomethingReceivedData = data
        doSomethingReceivedInvocations.append(data)
        if let doSomethingClosure {
            return doSomethingClosure(data)
        } else {
            return doSomethingReturnValue
        }
    }

}
// swiftlint:enable all

Is it possible to configure the mock generation to make it work?
I'm using Sourcery 2.1.2

👋🏻 Hey @r3econ ,

thank you for your bug report. Indeed, current implementation does not support method overloading it seems.

Possible solution would be to start including type information into the generated tracking variable names to make them uniquely-named, i.e.

-public var doSomethingReceivedData: Int?
+public var doSomethingIntReceivedData: Int?
...
-public var doSomethingCallsCount = 0
+public var doSomethingStringCallsCount = 0

Thanks a lot! 🙇
