Swift linking error: type metadata accessor for Module.Class

While working in Swift project, I have two modules, let's say

1. Base
2. Feature

Base has a SHService class from where I am calling a function of Feature module (of class SHCommon). Feature module is building without error but Base raises error in linking phase.

Snapshot of workspace:

Base.SHService

import Foundation
import Feature

class SHService {

    public func printMe(printString: String){
        SHCommon().printMe(printString: printString)
    }
}

Feature.SHCommon

import Foundation

public class SHCommon {

    public init(){}
    public func printMe(printString: String) {
        print(printString)
    }
}

Link error:

Any idea why this is happening?
