README
EFSafeArray is an extension to make array subscript safe, nil will be return instead of crash if index is out of range, it works on `iOS`, `macOS`, `watchOS` and `tvOS`.
## Example
To run the example project, clone the repo, and run `pod install` from the Example directory first.
## Requirements
- Xcode 16+
- Swift 6.0+
## Installation
### CocoaPods
EFSafeArray is available through [CocoaPods](http://cocoapods.org). To install it, simply add the following line to your Podfile:
```ruby
pod 'EFSafeArray'
```
### Swift Package Manager
The [Swift Package Manager](https://swift.org/package-manager/) is a tool for automating the distribution of Swift code and is integrated into the Swift compiler.
Once you have your Swift package set up, adding EFSafeArray as a dependency is as easy as adding it to the `dependencies` value of your `Package.swift`.
```swift
dependencies: [
.package(url: "https://github.com/EFPrefix/EFSafeArray.git", .upToNextMinor(from: "6.0.0.0"))
]
```
## Use
```swift
var list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
// Get Index
let xxx = list[0] // xxx: Int = 1
let zzz = list[0~] // zzz: Int? = 1
let yyy = list[10~] // yyy: Int? = nil
// Set Index
list[0] = 0 // list = [0, 2, 3, 4, 5, 6, 7, 8, 9, 0]
list[0~] = 1 // list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
list[10~] = 10 // list = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
// Get Bounds
let iiii = list[(0...5)~] // iiii: ArraySlice? = [1, 2, 3, 4, 5, 6]
let oooo = list[(-1...12)~] // oooo: ArraySlice? = [1, 2, 3, 4, 5, 6, 7, 8, 9, 0]
// Set Bounds
list[(0...5)~] = [1] // list = [1, 7, 8, 9, 0]
list[(-1...12)~] = [2, 3, 4, 5] // list = [2, 3, 4, 5]
```
