Split string into Array of Arrays [closed]

Answer 1

Okay You can do it recursively

let input = "001|apple|red|002|banana|yellow|003|grapes|purple"

let array = input.components(separatedBy: "|")


// Get Chunks from array
 extension Array {
      func getFirstElements(upTo position: Int) -> Array {
         let arraySlice = self[0 ..< position]
         return Array(arraySlice)
      }
  }

func recersivelyGetArray (array:[String], slice:inout [[String]]) {

  guard !array.isEmpty else{
    return
  }

  var copyArray = array

  var chunkSize = 3
  if  array.count >= 3 {
    chunkSize = 3
  } else {
    chunkSize = array.count
  }
  let threeElements =  copyArray.getFirstElements(upTo: chunkSize)
  slice.append(threeElements)

  copyArray.removeFirst(chunkSize)

  recersivelyGetArray(array: copyArray, slice: &slice)


}

var inoutResult = [[String]]()

recersivelyGetArray(array: array, slice: &inoutResult)

print(inoutResult) 

Output

Case 1 For Input

let input = "001|apple|red|002|banana|yellow|003|grapes|purple"

[["001", "apple", "red"], ["002", "banana", "yellow"], ["003", "grapes", "purple"]]

Case 2 For Input

let input = "001|apple|red|002|banana|yellow|003|grapes"

[["001", "apple", "red"], ["002", "banana", "yellow"], ["003", "grapes"]]
