Question

I want to split an array like shown below.

let arrayToSplit = [\"Europe|#|France|#|Paris\", \"Europe|#|Italy|#|Rome\", \"America|#|USA|#|Washington\", \"America|         


        

Answer 1

let arrayToSplit = ["Europe|#|France|#|Paris", "Europe|#|Italy|#|Rome", "America|#|USA|#|Washington", "America|#|Canada|#|Ottawa"]

let arrayOfLists = arrayToSplit.map{
    $0.componentsSeparatedByString("|#|")
}

let columns = Array(0..<3).map{ i in
    arrayOfLists.map{ list in list[i]}
}

print(columns)
//[["Europe", "Europe", "America", "America"], ["France", "Italy", "USA", "Canada"], ["Paris", "Rome", "Washington", "Ottawa"]]
