How to split array objects into two(or 2d array) by seperation character

Question

I want to split an array like shown below.

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


        

Answer 1

Not the best solution, but with the expected result (hints are in the code comments):

let arrayToSplit = ["Europe|#|France|#|Paris", "Europe|#|Italy|#|Rome", "America|#|USA|#|Washington", "America|#|Canada|#|Ottawa"]
var firstArray = [String]()
var secondArray = [String]()
var thirdArray = [String]()

for element in arrayToSplit {

    // new array with substrings divided by "|#|" e.g. ["Europe", "Europe", "America", "America"]
    let newArray = element.componentsSeparatedByString("|#|")
    firstArray.append(newArray[0])
    secondArray.append(newArray[1])
    thirdArray.append(newArray[2])
}

print("first array: \(firstArray)") // first array: ["Europe", "Europe", "America", "America"]
print("second array: \(secondArray)") // second array: ["France", "Italy", "USA", "Canada"]
print("third array: \(thirdArray)") // third array: ["Paris", "Rome", "Washington", "Ottawa"]
