Getting first letter from the string of first two words

Question

My string like :

Apple recipe  recapes

Mango Tengaer

Lemone T U

Grapes limoenis  Steyic genteur

So what i tried is :

if let bakery = filtered?[indexPath.row]{
   let stringInput = bakery.fruitsname
                let stringInputArr = stringInput.components(separatedBy: " ")
                var stringNeed = ""

                for string in stringInputArr {
                    stringNeed = stringNeed + String(string.characters.first!)
                }

    print(stringNeed)  // have to print first word first letter, second word second letter

}

But for me crash on this line when i do for my 3rd Lemone T U words.On this line:

 stringNeed = stringNeed + String(string.characters.first!)

Any help !!

Thanks

Try this. It separates the string into array of string and removes nil. So if the string has double space it filters that. Make sure that the string has minimum 2 words.

if let bakery = filtered?[indexPath.row]{
   let stringInput = bakery.fruitsname
   if stringInput.components(separatedBy: " ").count >= 2 {
         let stringNeed = (stringInput.components(separatedBy: " ").map({ $0.characters.first }).flatMap({$0}).reduce("", { String($0) + String($1) }) as NSString).substring(to: 2)
    print(stringNeed)  
  }
}
