JLSwiftUtilities

A collection of Swift helpers and utilities that I've written over the years that I think everyone could benefit from using it. This repo is constantly getting maintained and updated.

Extensions

UIView+Extensions

func addRoundCorners(cornerRadius: CGFloat = 20.0)

Adds a rounded corner to any UIViews.

Array+Extensions'

func sliced(from begin: Int, to end: Int) -> [Element]

An array slice solution to avoid the memory issues created with the default ArraySlice.

func duplicatesRemoved() -> [Element] 

Removes duplicates while preserving order. Requires array elements to conform to Hashable and Equatable.

UIImage+Extensions

class func imageFrom(color: UIColor, at size: CGSize = default) -> UIImage?

Generate an image from a color, at the specified size. The size defaults to 500.

UITabBarController+Extensions

func removeText()

Remove all texts from the tab bar and then move the icon down. The resulting tab bar looks like Instagram's.

Views

ColorPickerView

A simple but effective color picker.

PageViewController

Simply initialize it with a few view controllers to achieve a instagram-like pager look!

Classes

Haptic

A singleton class written to simplify the usage of haptic feedback generators which first shipped with iOS 10 on iPhone 7. It contains three main categories: selection feedbacks, impact feed backs and notification feedbacks. It is used through a singleton current.

Sample code to trigger a medium impact feedback:

Haptic.current.mediumImpact()
