To run the example project, clone the repo, and run pod install from the Example directory first.


AZAPicker is available through CocoaPods. To install
it, simply add the following line to your Podfile:

pod "AZAPicker"


Start with defining your own picker item type by implementing the AZAPickerItem protocol. This can be done with a simple struct:

struct MyPickerItem: AZAPickerItem {
    public let number: Int

    var description: String {
        return "(number)"

The AZAPicker view is instantiated with an instance of AZAPickerConfiguration and a CGRect for frame:

let config = AZAPickerConfiguration<MyPickerItem>(items: ...)
let pickerView = AZAPicker<MyPickerItem>(with: config, frame: .zero)

The onPickItem variable of the picker can be set to a function to receive updates about which item is currently selected. This function has to fulfill the type definition:

public typealias AZAPickerItemPicked = (AZAPicker<T>, T) -> ()

Which for this example becomes:

(AZAPicker<MyPickerItem>, MyPickerItem) -> ()


AZAPickerConfiguration, which is used when instantiating an instance of AZAPicker, holds the various properties which can be configured.

All configuration properties have default values.

items: [T: AZAPickerItem] (no default value)

The list of items to display in the picker. The items are of our own defined type, which conforms to the protocol AZAPickerItem, thus extending CustomStringConvertible.

defaultSelectedIndex: Int (default value: 0)

Which index should be selected when the picker is initialized.

selectedFont: UIFont (default value: UIFont.boldSystemFont(ofSize: 20))

Which font to use for the currently selected item.

selectedFontColor: UIColor (default value: UIColor.white)

Which font color to use for the currently selected item.

nonSelectedFont: UIFont (default value: UIFont.systemFont(ofSize: 14))

Which font to use for the non-selected items.

nonSelectedFontColor: UIColor (default value:

Which font color to use for the non-selected items.

selectionRadiusInPercent: Double (default value: 0.3)

The radius of the selection circle, in percent. (1.0 = 100 %)

selectionBackgroundColor: UIColor (default value:

Which background color to use for the selection circle.

gradientColors: [UIColor] (default value: [UIColor.white.withAlphaComponent(0.8), UIColor.white.withAlphaComponent(0)])

An array of gradient colors to use for the left and right sides.

gradientWidthInPercent: Double (default value: 0.4)

The gradient width, in percent, of the entire picker width. (1.0 = 100 %)

gradientPosition: GradientPosition (default value: GradientPosition.above)

Which position to use for the gradients, above or below the items.

itemWidth: Int (default value: 100)

Which width, in points, to use for the items.

sliderVelocityCoefficient: Double (default value: 60)

Velocity coefficient for the scroll views.
