Saystack

Saystack is a collection of classes and extensions for most common uses in any Swift project (mainly directed at iOS). It is a Swift counterpart to Haystack, which has been deprecated.

Saystack adds many convenience methods to native Swift API's. Multiple iOS and macOS frameworks are extended, including UIKit and Foundation. Both macOS and iOS are supported, but the framework is mainly targeting iOS, as macOS does not support UIKit.

Foundation

• Simple Email validation

let email1 = "some@example.com".isValidEmail // true
let email2 = "some@example".isValidEmail // false
let email3 = "1231241231".isValidEmail // false
let email3 = "@example.com".isValidEmail // false

• Pseudo Random number generation

// Random Integer between 0 and 1000
let rand1 = Int.random(0, upper: 1000)
// Random Integer between -1000 and 1000
let rand2 = Int.random(-1000, upper: 1000)

// Single Precision random between 0.00 and 1.00
let rand2 = Float.random()
// Double Precision random between 0.00 and 1.00
let rand3 = Double.random()

• Array Utilities

//
// Shuffling
//
var array = [ 1, 2, 3, 4, 5 ]
array.shuffle()

// Prints [ 5, 2, 3, 1, 4 ]
print(array)
let shuffled = [ 1, 2, 3, 4, 5 ].shuffled()

//
// Unique elements
//
let uniqueArray = [ 1, 2, 1, 2, 4, 5 ].unique()
// Prints [ 1, 2, 4, 5 ]
print(uniqueArray)

struct Person {
    var name : String
}

let people = [ Person(name: "John"), Person(name: "John"), Person(name: "Mark"), Person(name: "John") ]
let distinctArrayByProperty = people.distinct({ $0.name })
// Prints [ Person("John"), Person("Mark") ]
print(distinctArrayByProperty)

UIKit

Saystack provides several common UIKit extensions (not available on macOS).

• Environment detection

let environment = UIApplication.environment

if environment == .testFlight {
    ...
}

• UIImage resizing

let image = UIImage(named: "test-image.png")!
let resized = image.resize (CGSize(width: 100, height: 100))

• Searching for parent view types in UIView

@IBAction func tableCellButtonTap(sender: UIButton) {
    guard let cell = sender.parentTableViewCell() else { return }
    
    let indexPath = self.tableView.indexPathForCell(cell)
    
    // Use IndexPath
}

• Device information

let device = UIDevice.current.modelName

// Will use AdSupport.framework if available at runtime, otherwise vendorId.
let identifier = UIDevice.current.deviceIdentifier
