Introduction

XLSwiftKit is a collection of helpers and extensions we use internally. It is a constantly being updated with new snippets. Feel free to use it or to contribute.
You can see a list of helper functions and extensions here. Please keep that list updated if you add new functions

XLSwiftKit 2.0 is in Swift 3 syntax. If you are developing in Swift 2 please use version 1.x

Usage

import XLSwiftKit
// your code using XLSwiftKit

If you use XLSwiftKit in your app, We would love to hear about it! Drop us a line on twitter.

Examples

Follow these 3 steps to run Example project: Clone XLSwiftKit repository, open XLSwiftKit workspace and run the Example project.

Installation

CocoaPods

CocoaPods is a dependency manager for Cocoa projects.

To install XLSwiftKit, simply add the following line to your Podfile:

pod 'XLSwiftKit', '~> 3.0'

Carthage

Carthage is a simple, decentralized dependency manager for Cocoa.

To install XLSwiftKit, simply add the following line to your Cartfile:

github "xmartlabs/XLSwiftKit" ~> 3.0

Implemented functions

This is a list of the helper functions and extensions implemented in this pod.

Extensions

NSData

  • func toJSON() -> AnyObject?: serializes a NSData object to JSON representation

NSDate

  • func isOver18Years() -> Bool: returns if a date is over 18 years ago
  • func monthName() -> String: returns the month of a date in MMMM format

  • func day() -> String: returns the day of a date in dd format

UIApplication

  • class func topViewController(base: UIViewController? = UIApplication.sharedApplication().keyWindow?.rootViewController) -> UIViewController?: returns the top most view controller in the view hierarchy considering a base rootViewController.

  • func spin(duration: CFTimeInterval, rotations: CGFloat, repeatCount: Float): Spins a view around its z axis
  • static public func verticalStackView(views: [UIView], alignLeading: Bool = true, alignTrailing: Bool = true, frame: CGRect? = nil, width: CGFloat = UIScreen.mainScreen().bounds.width) -> UIView: returns a view containing the views passed as parameter as if it was a vertical stack view (putting all views vertically one after the other). Thought to be a iOS 8 alternative to real UIStackViews

UIViewController

  • func showError(title: String, message: String? = nil): shows an UIAlertController alert with error title and message

Double and Int

  • func currencyString() -> String?: Returns a formatted currency String from an Int or Double. Currency formatter used is defined under Constants.Formatters.currencyFormatter

String

  • func isValidAsEmail() -> Bool: Returns if a string is valid as email
  • func isValidAsPhone() -> Bool: Returns if a string is valid as phone number
  • func isNumberString() -> Bool: Returns if a string is composed just of numbers or ‘-‘ symbol
  • func findFirstNumberInString() -> String?: Returns the first number in a String if found
  • func renderedHeightWithFont(font: UIFont, width: CGFloat) -> CGFloat: Return the height necessary for a text given a width and font size. Same as heightForString extension on UIFont
  • func getFirstAndLastName() -> (String,String)?: Parses a first and a last name from a String. Takes last whitespace as separator for these values.
  • By conforming the String type to ParametrizedString protocol and specifying a parameter format like "{i}":
    • func parametrize(parameters: CustomStringConvertible...) -> String: Replace "{i}" substring with the i-th element of parameters. For example: "Hey {0}! It's been {1} years!".parametrize("Arnold", 3) gives you "Hey Arnold! It's been 3 years!"
    • parametrize(withDictonary dictonary: [Int: CustomStringConvertible]) -> String: Same behaviour as above but specifying the parameters as a dictonary.

UIImage

  • init(color: UIColor, size: CGSize = CGSize(width: 1, height: 1))
  • init(view: UIView)
  • init(image: UIImage, scaledToSize: CGSize)
  • class func imageWithColor(color: UIColor, size: CGSize = CGSize(width: 1, height: 1)) -> UIImage
  • class func imageWithView(view: UIView) -> UIImage
  • class func imageWithImage(image: UIImage, scaledToSize size: CGSize) -> UIImage: Returns a new image scaled to desired size
  • func imageScaledToSize(size: CGSize) -> UIImage: Same as previous
  • func saveToCameraRoll(completion: ((succeded: Bool) -> Void)? = nil): Saves an image to Saved Photos Album

UITableView

  • func setFooterWithSpacing(view: UIView): Adds a footer to a tableView that covers the rest of the screen.

UIDevice

  • func maxScreenLength() -> CGFloat: Returns the maximum screen length of the current device

The following helpers return if the device is of certain type depending on the devices maxScreenLength

  • func iPhone4() -> Bool
  • func iPhone5() -> Bool
  • func iPhone6() -> Bool
  • func iPhone6Plus() -> Bool

Other helpers:

  • fontSizeForDevice(size: CGFloat, q6: CGFloat = 0.94, q5: CGFloat = 0.86, q4: CGFloat = 0.80) -> CGFloat: Returns the suggested font size for every device (iPhone only).

UIFont

  • func heightForString(string: NSString, width: CGFloat) -> CGFloat: Return the height necessary for a text given a width and font size. Same as renderedHeightWithFont extension on String

Helpers

Constraints

  • func suggestedVerticalConstraint(value: CGFloat, q6: CGFloat = 0.9, q5: CGFloat = 0.77, q4: CGFloat = 0.65) -> CGFloat: Scale a value for a vertical constraint constant depending on the current device. Works for iPhone apps only. All coefficients have reasonable default values for vertical constraints
  • func suggestedHorizontalConstraint(value: CGFloat, q6: CGFloat = 0.9, q5: CGFloat = 0.77, q4: CGFloat = 0.77) -> CGFloat: Scale a value for a horizontal constraint constant depending on the current device. Works for iPhone apps only. All coefficients have reasonable default values for horizontal constraints

Appearances

This is a publis struct with functions inside:

  • static func removeBackImageIndicatorFromNavigationBar(): Removes the navigation bars backIndicator image

GCDHelper

  • static let mainQueue: DispatchQueue: Returns the main queue
  • static let backgroundQueue: DispatchQueue: Returns a background queue
  • static func delay(_ delay: Double, block: @escaping () -> ()): Executes a block after a given delay
  • static func runOnMainThread(_ block: @escaping () -> ()): Executes a block on the main thread
  • static func runOnBackgroundThread(_ block: @escaping () -> ()): Executes a block on the background queue
  • static func synced(_ lock: AnyObject, closure: () -> ()): Locks an object

Box

Box is a Wrapper: e.g. Used to wrap any structs in a class so that they can be used where AnyObject is required

Views

  • RoundedView, RoundedImageView and RoundedButton are subclasses of UIView, UIImageView and UIButton with a rounded appearance.
  • GradientView renders a gradient from an array of colors and a direction specified by the colors and direction properties. It spreads the colors evenly through the space.
  • OwnerView is intended to wrap xib views in order to reuse them in storyboards and also instantiate them in code.
    • Usage
      • Create a subclass of OwnerView
      • Set it as the File’s Owner of your xib.
      • Connect your xib’s view outlets to your subclass if any.
      • Override func viewForContent() -> UIView? to provide the xib’s view.
      • Override func setup() to initialize the view. Your xib’s view will be accessible through the contentView property.

Others

  • public func JSONStringify(value: AnyObject, prettyPrinted: Bool = true) -> String: Converts a JSON object to a printable String
