NumberWheelPicker is a Swift package that provides two simple and customizable components for making it easy for users to input whole or decimal numbers.


  • Built using native SwiftUI components
  • Fully compatible with light and dark mode
  • Customizable number of digits for whole and fractional parts
  • Preselected values
  • Compatible with iOS 14 and above

Here are images from both pickers (note that they were recorded with a black background during snapshot testing, but they blend in with no issues in the real UI).

Swift Package Manager

  • In Xcode, select “File” → “Add Packages…”
  • Enter [email protected]:kublaios/NumberWheelPicker.git

…or you can add the following dependency to your Package.swift:

.package(url: "[email protected]:kublaios/NumberWheelPicker.git", from: "0.0.1")


Add WholeNumberWheelPicker.swift file to your project. If you want the decimal picker, add DecimalNumberWheelPicker.swift, too.


If you installed using SPM, make sure to import the package first:

import NumberWheeelPicker

Then, you should be able to create either of the pickers like below:

let wholeNumberPicker = WholeNumberWheelPicker(viewModel: .init(length: 3, preselectedValue: 123))
let decimalNumberPicker = DecimalNumberWheelPicker(viewModel: .init(preselectedValue: 555.777, wholeParthLength: 3, fractionalPartLength: 3))


You can customize the appearance of both number pickers simply by changing the view model’s properties.

For example, to set a custom delimiter between the whole and fractional parts:

decimalNumberPickerViewModel.delimiter = ","
