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

|  |  |  |
| Image | UI/NSImage |

## 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
```swift
var name = ""
EditValueView(key: "name", value: name)
.onUpdate { newValue in
name = newValue
}
```
- Initialize with keyPath
```swift
EditValueView(target, key: "name", keyPath: \Item.name)
.onUpdate { newValue in
target[keyPath: \.name] = newValue
}
```
- Initialize with binding
```swift
@State var name: String = ""
EditValueView(key: "name", binding: $name)
```
#### Update Handler
You can receive an edit callback when you press the `save` button.
```swift
EditValueView(target, key: "name", keyPath: \Item.name)
.onUpdate { newValue in
// update
}
```
#### Input Validation
You can validate input values.
```swift
EditValueView(target, key: "name", keyPath: \Item.name)
.validate { newValue -> Bool in
// input validation
return !name.isEmpty
}
```
### UIKit
```swift
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`.
```swift
struct Item: Codable {
var name: String
var date: Date
}
struct Message: Codable {
var content: String
var item: Item?
}
```
```swift
// Confirm to `DefaultRepresentable` protocol
extension Item: DefaultRepresentable {
static var defaultValue: Self {
.init(name: "name", date: Date())
}
}
```
```swift
// give default value
EditValueView(target, key: "item", keyPath: \Message.item, defaultValue: .init(name: "name", date: Date()))
```
