Simple sorting in Swift. Sort array of int, array of string, and by a property in instances of a class

simple-sorting

// sort int
var ar = [3,2,5,6]

sort(&ar, <)
// or
ar = ar.sorted(<)

print(ar);

// sort by member in class
class Person {
    var name = ""
    var age = 0
    
    init(name: String, age:Int) {
        self.name = name
        self.age = age
    }
}

var people = [ Person(name: "bob", age: 23), Person(name: "alice", age: 56), Person(name: "david", age: 88)]


sort(&people) { $0.name < $1.name }

print(people);

for person in people {
    print(person.name);
}

do you know how to run the sort by converting the strings to a number?

finally figured this shit out.

self.zones = nearbyZones.sorted { $0["distanceinfeet"].string!.compare($1["distanceinfeet"].string!, options: .NumericSearch) == NSComparisonResult.OrderedAscending }
