Condition checking on NSMutableDictionary

Question

I have NSMutableDictionary with (key,value) pairs.For JournalId the key is "journalId".I just want to check whether my dictionary contains specific "journalId", for eg, 29. If it exists, need to print the corresponding title and userId. eg.

{
    journalId = 28;
    title = Creed;
    userId = 105; } {
    journalId = 29;
    title = Fg;
    userId = 105; } {
    journalId = 30;
    title = Dhh;
    userId = 105; }

I want to check in my dictionary whether it has journalId value = 28.

if (dictValues["journalId"] == 28){
print(dictValues["title"]
}

The above method shows error. Thanks in advance.

What you have is not even data with NSMutableDictionary. It's raw data before converted into JSON. Why do you even want to use NSMutableDictionary in Swift? Why not using Dictionary instead? — El Tomato, Dec 07 '16 at 14:04

guard dictValues["journalId"] as! Int == 28 else {
    print("key Not found")
    return // exit the function
}
let title = dictValues["title"] as! String
print("\(title)")

Try this:

if let journalId = dictValues["journalId"] as? Int, journalId == 28 {
  print(dictValues["title"])
}

NSDictionary subsctiption returns an object of type AnyObject?. This code should resolve your problem

if (dictValues["journalId"] as? Int == 28) {
   print(dictValues["title"])
}
