EditValueView

Library that makes easy to display property edit screens for SwiftUI.

Demo

String	Bool	Int

Double	Date	Color

Image	UI/NSImage

Array	Dictionary

Enum(CaseIterable)	Enum(CaseIterable & RawRepresentable)

Codable

Supported types

• String
• Bool
• any Numerics
• Date
• Color/UIColor/NSColor/CGColor/CIColor
• Image/UIImage/CGImage/CIImage (iOS Only)
• Array(Codable)
• Dictionary(Codable)
• CaseIterable
• CaseIterable & RawRepresentable
• Codable

Usage

Note If you want to use the camera for editing images, you must add a key named NSCameraUsageDescription to the info.plist file.

SwiftUI

Initialize

• Initialize with key and initial value

  var name = ""
  EditValueView(key: "name", value: name)
    .onUpdate { newValue in
        name = newValue
    }
  

• Initialize with keyPath

  EditValueView(target, key: "name", keyPath: \Item.name)
    .onUpdate { newValue in
        target[keyPath: \.name] = newValue
    }
  

• Initialize with binding

  @State var name: String = ""
  EditValueView(key: "name", binding: $name)
  

Update Handler

You can receive an edit callback when you press the save button.

EditValueView(target, key: "name", keyPath: \Item.name)
    .onUpdate { newValue in
        // update
    }

Input Validation

You can validate input values.

EditValueView(target, key: "name", keyPath: \Item.name)
    .validate { newValue -> Bool in
        // input validation
        return !name.isEmpty
    }

UIKit

let vc = EditValueViewController(target, key: "name", keyPath: \Item.name)
vc.onUpdate = { target, newValue in
    // update
}
vc.validate = { target, newValue -> Bool in
    // input validation
}

Protocol

When using optional types, type hints for Codable cannot be displayed when nil is used. To avoid such problems, provide a default value in accordance with the protocol named DefaultRepresentable.

struct Item: Codable {
    var name: String
    var date: Date
}

struct Message: Codable {
    var content: String
    var item: Item?
}

// Confirm to `DefaultRepresentable` protocol
extension Item: DefaultRepresentable {
    static var defaultValue: Self {
        .init(name: "name", date: Date())
     }
}

// give default value
EditValueView(target, key: "item", keyPath: \Message.item, defaultValue: .init(name: "name", date: Date()))
