Is there any simple method to convert string that looks like that: [[1,2],[1,3],[1,4]] to array with arrays?
I will be glad.

3That does not look like the description of a dictionary. How did you obtain the string? – Better choose a format like JSON if you have to convert dictionaries/arrays to a string and back.Martin R– Martin R2017-02-22 20:43:16 +00:00Commented Feb 22, 2017 at 20:43

The easiest option is to convert it to JSON and back:
let str = "[[1,2],[1,3],[1,4]]"
let data = str.data(using: .utf8)!
do {
let json = try JSONSerialization.jsonObject(with: data, options: [])
if let arr = json as? [[Int]] {
print(arr)
}
} catch {
print(error)
}

I made that method for it and it works:
func convertToArray(string: String) -> [[Int]] {
var arrayOrder = 0
var mainArray: [[Int]] = []
var array: [Int] = []
for character in string.characters {
if character == "[" {
arrayOrder += 1
}
if arrayOrder >= 2 && character != "[" && character != "]" && character != "," {
let integer: Int = Int(String(character))!
array.append(integer)
}
if character == "]" {
if arrayOrder >= 2 {
mainArray.append(array)
array = []
}
arrayOrder -= 1
}
}
return mainArray
}

It is only if we have one level of arrays in main array.
