# Extensions for Swift

A collection of small extensions and custom operators.

[DocC documentation](https://fizker.github.io/swift-extensions/documentation/fzkextensions/)

## How to use

1. Add `.package(url: "https://github.com/fizker/swift-extensions.git", from:"1.0.0")` to the list of dependencies in your Package.swift file.

2. Add `.product(name: "FzkExtensions", package: "swift-extensions")` to the dependencies of the targets that need to use the models.

3. Add `import FzkExtensions` to a file to gain access to the extensions and operators.

## Extensions

Array#removing(at index:)

```swift

let measurements: [Double] = [1.1, 1.5, 2.9, 1.2, 1.5, 1.3, 1.2]

let removed = measurements.removing(at: 2)

print(removed)

// Prints "[1.1, 1.5, 1.2, 1.5, 1.3, 1.2]"

```

RandomAccessCollection#[safe index:]

```swift

let array = [1,2,3]

assert(array[safe: -1] == nil)

assert(array[safe: 0] == 1)

assert(array[safe: 1] == 2)

assert(array[safe: 2] == 3)

assert(array[safe: 3] == nil)

```

## Operators

Configurator `~`

```swift

let view = UIView()

view.addGestureRecognizer(UITapGestureRecognizer() ~ {

    $0.numberOfTapsRequired = 2

    $0.modifierFlags = [ .command ]

})

```

Optional set `??=`

```swift

// Given the class Foo

class Foo {

    var bar: Int?

}

func ensureValue(foo: Foo) {

    // If foo.bar is nil, it now becomes 1.

    // If it is not nil, it will remain unchanged.

    foo.bar ??= 1

}

```
