Introducing PickerKit for SwiftUI

Say hi to PickerKit - an open-source SwiftUI package that contains various image pickers, cameras, document scanners, file pickers, picker utilities, etc. for your everyday picker needs.

Available Features

The first PickerKit beta was just released, but already has many pickers and picker-related views:

• Camera can be used to take photos and handle them as images.
• ColorPickerBar adds a color picker to a horizontal or vertical bar with additional colors.
• DocumentScanner can be used to scan documents and handle them as images.
• FilePicker can be used to pick any file from the Files app.
• ImagePicker can be used to pick images from the user’s photo library.
• MultiPicker can be used to pick multiple items in e.g. a list or form.

There are also models and utilities, like the OptionalBinding and CancellableResult models.

Camera

The Camera picker uses the ImagePicker with a .camera picker configuration, and can take pictures with the device camera:

Camera(
    isPresented: $isPickerPresented,
    action: { result in
        switch result {
        case .cancelled: break
        case .failure: break
        case .success(let image): // Handle image here...
        }
    }
)

If you provide a value for isPresented, the camera will automatically dismiss itself when it’s done.

DocumentScanner

The DocumentScanner picker wraps a VNDocumentCameraViewController and can scan one or multiple documents with the device camera:

DocumentScanner(
    isPresented: $isPickerPresented,
    action: { result in
        switch result {
        case .cancelled: break
        case .failure: break
        case .success(let scan): // Handle scan here...
        }
    }
)

If you provide a value for isPresented, the scanner will automatically dismiss itself when it’s done.

FilePicker

The FilePicker picker wraps a UIDocumentPickerViewController and can pick files from Files:

FilePicker(
    documentTypes: [.content],
    isPresented: $isPickerPresented,
    pickerConfig: { picker in
        picker.allowsMultipleSelection = true
    },
    action: { result in
        switch result {
        case .cancelled: break
        case .failure: break
        case .success(let urls): self.urls = urls
        }
    }
)

If you provide a value for isPresented, the picker will automatically dismiss itself when it’s done.

ImagePicker

The ImagePicker picker wraps a UIImagePickerController and can pick images in various ways:

ImagePicker(
    sourceType: .photoLibrary,
    isPresented: $isPickerPresented,
    pickerConfig: { picker in },
    action: { result in
        switch result {
        case .cancelled: break
        case .failure: break
        case .success(let image): images.append(image)
        }
    }
)

If you provide a value for isPresented, the picker will automatically dismiss itself when it’s done.

ColorPickerBar

The ColorPickerBar adds a ColorPicker to a horizontal or vertical bar with extra colors and actions:

ColorPickerBar(
    axis: .horizontal, 
    value: $color
)
.colorPickerBarConfig(.init(
    barColors: .colorPickerBarColors(withClearColor: true),
    opacity: true,
    resetButton: true,
    resetValue: .black
))
.colorPickerBarStyle(.init(
    animation: .bouncy,
    spacing: 10,
    colorSize: 30,
    selectedColorSize: 45
))

If you provide a value for isPresented, the picker will automatically dismiss itself when it’s done.

MultiPicker

A MultiPicker can be used to pick multiple Identifiable values in a List, Form, stack or grid:

MultiPicker(
    items: items,
    selection: $selection
) { item, isSelected in
    MultiPickerItem(isSelected: isSelected) {
        Text(item.name).tag(item)
    }
}

You can use any custom item view, and wrap it in a MultiItemPickerView to automatically add a checkmark to the selected values.
