Add https://github.com/dagronf/DSFColorPicker to your project

Configuration

Unfortunately, Xcode has a LOT of problems displaying @IBDesignable content in Interface Builder if the content comes from a Swift Package. Sometimes it displays, sometimes it doesn't and displays an error about tvOS. I've reported this to Apple in many forms over the years and nothing has been done about it - my guess is the emphasis is moving heavily to SwiftUI previews and this bug is becoming less and less relevant to them.

So what does this mean? You will still be able to create and configure your color picker within Interface Builder, however the pretty previews may or may not display in Interface Builder. Your app will display fine, its just that IB has platform problems when it comes to Swift Package imports.

Interface builder

You can configure your control in interface builder completely. Drop in a custom view, change the custom type to DSFColorView (or an overload) and choose your display theme using the 'Named Theme' setting in the custom types

	let theme = DSFColorPickerTheme(name: "default", argbValueGrid: [
		[0xF5402C, 0xEB1360, 0x9C1BB1, 0x6634B8, 0x3D4DB7],
		[0x47AE4A, 0x009687, 0x01BBD5, 0x00A6F6, 0x0C93F5],
		[0x89C43F, 0xCCDD1E, 0xFFEC17, 0xFEC001, 0xFF9800],
		[0x000000, 0x5E7C8B, 0x9D9D9D, 0x7A5447, 0xFF5506]]
	)
	self.colorView.selectedTheme = theme

A single row with no recents

	let theme = DSFColorPickerTheme(name: "Simple Line", argbValueGrid: [
		[0xE0BA4240, 0xE0F0C976, 0xE096A873, 0xE089C9B8, 0xE0AFE6E4, 0xE07AA3C0, 0xE08B719F, 0xE0DB849A]]
	)
	self.showRecents = false
	self.colorView.selectedTheme = theme

The number of recent colors (if shown) is the same as the number of columns in the color grid

  • Show or hide the themes in the control
  • Show or hide the 'selected' button
  • Show or hide recent colors
  • Show or hide titles within the control
  • Set the cell width and height
  • Set the spacing between the color cells

Color sampling support

As of macOS 10.15, your app will require Screen Recording permissions to use the color sampler (the eye dropper).

The first time a user selects the eye-dropper, macOS will display a dialog asking for permission.

You can view the Screen Recording permissions for apps in the system preferences Security & Privacy pane.

System Preferences > Security & Privacy > Privacy > Screen Recording

Theme support

Supply a set of themes, and configure the control to display the theme selector.

Drag and drop support

  • Drag from the picker to any other component (eg. a color well) that supports dropping colors
  • Drag colors into the control

Dark mode support

Automatically adjusts to light and dark modes dynamically

High contrast support

Dynamically adjusts to high-contrast display modes

Accessibility support (preliminary)

  • High contrast support
  • VoiceOver reads out 'named' color views as they are interacted with (" Color Selector")

Changes

2.0.0

  • Updated the package to depend on the DSFColorSampler package instead of embedding an older version of the source.

  • Removed 'direct' method of installing as the SPM package now depends on DSFColorSampler.
