Array element checking in swift

Question

Currently implementing a favourite function to my application which is based on quotes. I would like to perform a check for if the user has already saved an element to an ar

Answer 1

The better and quick way to find out an element in an array is:

if contains(yourFavArray, stringStatement){
  //Contains you can write your logic
}

Change your favouriteArray as below:

var favouriteQuotesArray: [String] = NSUserDefaults.standardUserDefaults().objectForKey("thekey") as! [String]

Edited:

 if let foundIndex = find(favouriteQuotesArray, dreamFact.dreamArray[factIndex]) {
     sender.setTitle(Constants.like, forState: .Normal)
     favouriteQuotesArray.removeAtIndex(foundIndex)
 }
