How to sort 1 array in Swift / Xcode and reorder multiple other arrays by the same keys changes

Question

Sorry for the complex wording of the question. My main experience is with PHP and it has a command called array_multisort. The syntax is below:

bool array_mu         


        

Answer 1

I believe AlainT:s solution is to prefer, but to extend the variety of options, below follows a solution mimicking what a zip5 method could let us achive (in case we could use zip for zipping together 5 sequences instead of its limit of 2):

/* example arrays */
var firstName: [String] = ["David", "Paul", "Lisa"]
var age: [Int] = [17, 27, 22]
var city: [String] = ["London", "Rome", "New York"]
var country: [String] = ["England", "Italy", "USA"]
var active: [Int] = [906, 299, 5060]

/* create an array of 5-tuples to hold the members of the arrays above.
   This is an approach somewhat mimicking a 5-tuple zip version.        */
var quinTupleArr : [(String, Int, String, String, Int)] = []
for i in 0..
