# SafeCollection

![Swift](https://img.shields.io/badge/Swift-5.0-orange.svg)

[![Build Status](https://travis-ci.org/devxoul/SafeCollection.svg)](https://travis-ci.org/devxoul/SafeCollection)

[![CocoaPods](http://img.shields.io/cocoapods/v/SafeCollection.svg)](https://cocoapods.org/pods/SafeCollection)

[![Carthage compatible](https://img.shields.io/badge/Carthage-compatible-4BC51D.svg?style=flat)](https://github.com/Carthage/Carthage)

SafeCollection provides a safer way to deal with subscripts. Inspired by Swift's [LazyCollection](https://developer.apple.com/documentation/swift/lazycollection).

## At a Glance

```swift

let arr = ["A", "B", "C"]

arr[0]    // "A"

arr[100]  // fatal error: Array index out of range 😟

arr.safe[0]   // Optional("A")

arr.safe[100] // nil 😄

```
