extension String {
    func capitalizingFirstLetter() -> String {
        return prefix(1).capitalized + dropFirst()
    }
    func getCamelCasedString () -> String {
        var camelCasedStringCollection = [String]()
        let stringComponents = components(separatedBy: " ")
        for var oneComponent in stringComponents {
            oneComponent = oneComponent.capitalizingFirstLetter()
            camelCasedStringCollection.append(oneComponent)
        }
        return camelCasedStringCollection.joined(separator: " ")
    }
}

/*
Usage:
let test = "asda qwer edc"
print(test.getCamelCasedString())
Output:
