Use Tuple Comparison Operators in Swift

Written by Team Kodeco

In Swift, you can use comparison operators like <, >, <= and >= to compare tuples. When comparing tuples, each element is compared in the order they appear in the tuple.

Here’s an example of how to use the less than operator < to compare two tuples:

// Example 1: Compares first element
let tuple1 = (1, "banana")
let tuple2 = (2, "apple")

if tuple1 < tuple2 {
  print("Tuple 1 is less than Tuple 2")
}
if tuple2 < tuple1 {
  print("Tuple 2 is less than Tuple 1")
}
// Output: Tuple 1 is less than Tuple 2

// Example 2: First element is equal, so compares second element
let tuple3 = (1, "banana")
let tuple4 = (1, "apple")

if tuple3 < tuple4 {
  print("Tuple 3 is less than Tuple 4")
}
if tuple4 < tuple3 {
  print("Tuple 4 is less than Tuple 3")
}
// Output: Tuple 4 is less than Tuple 3
