type Alias function with closure callback in swift

just_testing.swift

    typealias function = (String) -> String
    let someProperty: function = {(value: String) -> String in 
        // create a default value for someProperty inside this closure
        // someValue must be of the same type as SomeType
        return value
    }
    
    print(someProperty("abiodun"))

// This can be refactored to this

 typealias function = (String) -> String
    let someProperty: function = {(value: String) in 
        value
    }
    
    print(someProperty("abiodun"))
