Count occurrences of a value-CodePudding

I'm trying to get the count of value from a key,value pairs of a [String: Any] dictionary

for item in mainData {
var answerDict = [String: Any]()
var totalCountValOne = 0

for (key,value) in item.extraAnswers {
   if key.contains("correct") {
      answerDict[key] = value
   }
}
for (key,value) in answerDict {
   let lastChar = key.last
    answerFinalDict[Int(lastChar?.description ?? "") ?? 0] = "\(value)"
    print("value \(value)")
                        
    for (key, value) in answerDict {
    print("\(key) -> \(value)") 
  }
}

Output of print value:

value 0
value 0
value 1
value 0
value 0
value 1
value 0
value 0
value 1
value 0
value 0
value 0
value 0
value 0
value 1
value 0
value 1
value 1
value 0
value 0

Output of print(answerDict)

["correct_2": 1, "correct_5": 0, "correct_4": 1, "correct_3": 0, "correct_1": 0]

Output of print("\(key) -> \(value)")

correct_2 -> 1
correct_5 -> 0
correct_4 -> 1
correct_3 -> 0
correct_1 -> 0

Please note that print outputs have been shortened for readability.

What I'm trying to achieve is to get the count of occurrences of value 1

I get errors as value of type Any can't be compared to int 1, casting caused crash, can't use for loop to check for value 1 to do totalCountValOne = 1

Any ideas?

CodePudding user response：

If you want to find the occurrences of value 1 from answerDict

Try this:

If the value is Int

 print(answerDict.filter({$0.value as? Int == 1 }).count)

If the value is String

print(answerDict.filter({$0.value as? String == "1" }).count)
