1. TVButton

Today, we start with TVButton, a library that recreates the beautiful parallax effect that you can see on Apple TV, on your UIButton control. The effect is triggered by a long press or dragging.

To use the parallax effect, you need at least two/three layers of images with the same dimensions. Below is an implementation example:

let bg = TVButtonLayer(image: UIImage(named: "TVBG.png")!)
let pattern = TVButtonLayer(image: UIImage(named: "TVBtnPattern.png")!)
let top = TVButtonLayer(image: UIImage(named: "TVbtnTop.png")!)
tvButton.layers = [background, pattern, top]

Then you can customize the parallax-effect intensity by changing the following property:

tvButton.parallaxIntensity = 1.3

2. TKRubberIndicator

TKRubberIndicator is a library made in Swift that’ll add a rubber animated page control onto your app.

To use it, you need to import the TKRubberPageControl framework first. Then, you need to add the following code into your controller:

override func viewDidLoad() {

page.center = self.view.center
page.valueChange = {(num) -> Void in
print("Closure : Page is \(num)")
page.addTarget(self, action: "targetActionValueChange:", forControlEvents: UIControlEvents.ValueChanged)

page.numberOfpage = 2

@IBAction func pageCountChange(sender: UISegmentedControl) {
page.numberOfpage = (sender.selectedSegmentIndex + 1) * 2
func targetActionValueChange(page:TKRubberIndicator){
print("Target-Action : Page is \(page.currentIndex)")

3. DimensionsPickerView

In a few lines of code, DimensionsPickerView will let you add a beautiful view that can be used to measure data input.

Placeholder unit, font color, spacing, and border color/width are customizable in the following way:

sizePickerView.textFieldConfigureBlock = { index, field in
switch index {
case 0:
field.placeholder = "w"
case 1:
field.placeholder = "h"

sizePickerView.pickerFieldConfigureBlock = { field in
field.text = "m"

sizePickerView.tintColor = UIColor.red
sizePickerView.spacingBetweenValueFields = 0
sizePickerView.spacingBetweenUnitAndValues = 30

sizePickerView.layer.cornerRadius = 5
sizePickerView.layer.borderColor = UIColor.white.cgColor
sizePickerView.layer.borderWidth = 1.5

4. TransitionButton

TransitionButton is a library used to add a UIButton with loading and transition animations.

First of all, consider that TransitionButton is a subclass of UIButton. TransitionButton also adds two main methods:

  • startAnimation(): when called will start animating the button with a loading spinner
  • stopAnimation(...): when called will stop animating the button

5. Sliders

Lastly, Sliders is a library made entirely in SwiftUI. It allows you to create customizable horizontal and vertical sliders on iOS, macOS, and Mac Catalyst.

Among the personalizations, we find:
