Extensions and syntactic sugar to enrich the Swift standard library, iOS frameworks, and [SwifterSwift](https://github.com/SwifterSwift/SwifterSwift).
## Installation
### CocoaPods:
```ruby
pod 'SweeterSwift'
```
### Swift Package Manager:
```swift
dependencies: [
.package(url: "https://github.com/yonat/SweeterSwift", from: "1.2.6")
]
```
## Usage
* [Auto Layout](#auto-layout)
* [Bundle](#bundle)
* [Codable](#codable)
* [DateFormatter](#dateformatter)
* [NotificationCenter](#notificationcenter)
* [NSAttributedString](#nsattributedstring)
* [NSManagedObjectContext](#nsmanagedobjectcontext)
* [String](#string)
* [Swift Standard Library](#swift-standard-library)
* [TimeInterval](#timeinterval)
* [UIApplication](#uiapplication)
* [UILabel / UITextView](#uilabel-uitextview)
* [UIStackView](#uistackview)
* [UIView](#uiview)
### Auto Layout
Add button at the center of view:
```swift
view.addConstrainedSubview(button, constrain: .centerX, .centerY)
```
Put label over textField:
```swift
view.constrain(label, at: .leading, to: textField)
view.constrain(textField, at: .top, to: label, at: .bottom, diff: 8)
```
Add child view controller covering all but the bottom margin:
```swift
addConstrainedChild(vc, constrain: .bottomMargin, .top, .left, .right)
```
### Bundle
App name with reasonable fallback to process name:
```swift
let appName = Bundle.main.name
```
App info string with name, version, and build number:
```swift
let appInfo = Bundle.main.infoString // "MyApp 1.0 #42"
```
### Codable
Create object from a dictionary:
```swift
let decodableObject = MyDecodableClass(dictionary: aDictionary)
```
Export object to a dictionary:
```swift
let aDictionary = encodableObject.dictionary
```
### DateFormatter
Create with format:
```swift
let dateFormatter = DateFormatter(format: "cccc, MMMM dd")
```
### NotificationCenter
Post a local notification using `NotificationCenter.default`:
```swift
notify(notificationName, userInfo: infoDictionary)
```
Respond to a local notification from `NotificationCenter.default`:
```swift
observeNotification(notificationName, selector: #selector(someFunc))
```
### NSAttributedString
Create from HTML:
```swift
let attributedString = NSAttributedString(htmlString: "Hello, world!")
```
Turn a substring into a link:
```swift
mutableAttributedString.link(anchorText: "Hello", url: "https://ootips.org")
```
### NSManagedObjectContext
Dump contents to console for debugging:
```swift
managedObjectContext.printAllObjects()
```
Create a copy of the store for backup or for using later as initial setup:
```swift
managedObjectContext.backupStore()
```
### String
Separate CamelCase into capitalized words:
```swift
let words = "winterIsComing".unCamelCased // "Winter Is Coming"
```
Change CamelCase into snake_case:
```swift
let key = "winterIsComing".camelToSnakeCased // "winter_is_coming"
```
### Swift Standard Library
Index of current enum case in `allCases`:
```swift
let index = MyEnum.someCase.index
```
Unwrap collection, shorthand for `compactMap { $0 }`:
```swift
let nonOptionals = optionalsCollection.compact
```
Avoid retain cycles when passing a member function as an @escaping closure:
```swift
var closure = weak(self, in: MyClass.someFunction)
```
### TimeInterval
Standard time intervals:
```swift
let myInterval: TimeInterval = .year + .month + .week + .day + .hour + .minute
```
### UIApplication
Find the top-most view controller:
```swift
let topVC = UIApplication.topViewController()
```
Present modal over the top view controller:
```swift
UIApplication.present(modalVC)
```
### UILabel / UITextView
Create a label with links by using a `UITextView` to auto-detect links and simulate `UILabel` appearance:
```swift
let hyperlinkedLabel = UITextView(simulatedLabelWithLinksInText: "More at https://ootips.org")
```
### UIStackView
Remove an arranged subview from the view hierarchy, not just the stack arrangement:
```swift
stackView.removeArrangedSubviewCompletely(subview)
```
Remove all arranged subviews from the view hierarchy, not just the stack arrangement:
```swift
stackView.removeAllArrangedSubviewsCompletely()
```
### UIView
Search the view hierarchy recursively for a subview that meets a condition:
```swift
let blueSubview = view.viewInHierarchy(where { $0.backgroundColor == .blue })
```
Search the view hierarchy recursively for a subview with a specific class:
```swift
let button = view.viewWithClass(UIButton.self)
```
