Swift 3 - 用字典值匹配用戶輸入

Question

我的應用程序的用戶將被測試他們的英語。他們將通過在該單詞旁邊放置複選標記來從列表中選擇不同的單詞。他們只想選擇名詞的單詞。例如，如果他們正確選擇了5個，我該如何向他們展示50％的分數。我認爲我需要根據用戶的輸入過濾字典值。用戶的輸入是一個數組。對此進行編碼的最佳方式是什麼？

試試下面的代碼： - 100％的工作

 let myDictionary : [String : Any] = 
     [ "Nouns":["One","Two","Three","Four","Five","Six","Seven","Eight","Nine","Ten"], 
"Verbs":["Eat","play","dance","walk","run","sing","read","write","go","come"]] 
    var myUserSelectedArray:[String] = ["One","come","Three","go","Five","x","Six","x","x","Ten"]; 

    let myNounArray = myDictionary["Nouns"] as? [String]; 
    let myVerbArray = myDictionary["Verbs"] as? [String]; 
    let set1:Set<String> = Set(myUserSelectedArray); 
    let set2:Set<String> = Set(myNounArray!); 
    let set3:Set<String> = Set(myVerbArray!); 
    let scroeInNoun = set1.intersection(set2).count; 
    let scroeInVerb = set1.intersection(set3).count; 
    print ("score in Verb \((scroeInVerb * 100)/set2.count) %") 
    print ("score in noun \((scroeInNoun * 10)/set3.count) %") 
    let finalScore = (scroeInNoun + scroeInVerb) * 100/((myNounArray?.count)! + (myVerbArray?.count)!) 
    print ("final score in noun \(finalScore) %")
