## Overview
The **`min()` method** can be used to get the minimum element of an array.
## Syntax
```swift
arr.min()
```
## Parameters
**arr**: This is the array whose minimum element we want to find.
## Return value
The value returned is the minimum element of the array. If the array has no element, a `nil` value is returned.
## Code example


// create arrays
let evenNumbers = [2, 10, 4, 12, 6, 8]
let negativeNumbers = [-1.3, -0.5, 0.002, 4.5]
let decimalNumbers = [45.7, 44.2, 90.0, 23.3]

// get minimum elements
let minEvenNo = evenNumbers.min()!
let minNegNo = negativeNumbers.min()!
let minDecNo = decimalNumbers.min()!

// print results
print(minEvenNo)
print(minNegNo)
print(minDecNo)

## Code explanation
* Lines 2–4: We create some arrays.
* Lines 7–9: We invoke the `min()` method on the arrays we created. Then, we store the results in some variables.
* Lines 12–14: We print the results to the console.

How can we get the minimum element of an array in Swift

Use the min() method to get the minimum element of an array in Swift, returning nil if empty.
