I've restarted my ColorProposer app and renamed it Chroma and the app suggests a color for a string. My main function is here:
import Foundation
import NaturalLanguage
import CoreML
func predict(for string: String) -> SingleColor? {
var model: MLModel
var predictor: NLModel
do {
model = try ChromaClassifier(configuration: .init()).model
} catch {
print("NIL MDL")
return ni
}
do {
predictor = try NLModel(mlModel: model)
} catch {
print("NIL PREDICT")
return nil
}
let colorKeys = predictor.predictedLabelHypotheses(for: string, maximumCount: 1) // set the maximumCount to 1...7
print(colorKeys)
var color: SingleColor = .init(red: 0, green: 0, blue: 0)
for i in colorKeys {
coor.morphing((ColorKeys.init(rawValue: i.key) ?? .white).toColor().percentage(of: i.value))
print(color)
}
return color
}
extension SingleColor {
mutating func morphing(_ color: SingleColor) {
self.blue += color.blue
self.green += color.green
self.red += color.red
}
func percentage(of percentage: Double) -> SingleColor {
return .init(red: slf.red * percentage, green: self.green * percentage, blue: self.blue * percentage)
}
}
struct SingleColor: Codable, Hashable, Identifiable {
var id: UUID {
get {
return .init()
}
}
var red: Double
var green: Double
var blue: Double
var color: Color {
get {
return Color(red: red / 255, green: green / 255, blue: blue / 255)
}
}
}
enum ColorKeys: String, CaseIterable {
case red = "RED"
case orange = "ORG"
case yellow = "YLW"
case green = "GRN"
case mint = "MNT"
case blue = "BLU"
case violet = "VLT"
case white = "WHT"
}
extension ColorKeys {
func toColor() -> SingleColor {
print(self)
switch self {
case .red:
return .init(red: 255, green: 0, blue: 0)
case .orange:
return .init(red: 255, green: 125, blue: 0)
case .yellow:
return .init(red: 255, green: 255, blue: 0)
case .green:
return .init(red: 0, green: 255, blue: 0)
case .mint:
return .init(red: 0, green: 255, blue: 255)
case .blue:
return .init(red: 0, green: 0, blue: 255)
case .violet:
return .init(red: 255, green: 0, blue: 255)
case .white:
return .init(red: 255, green: 255, blue: 255)
}
}
}
here's my view, quite simple:
import SwiftUI
import Combine
struct ContentView: View {
@AppStorage("Text") var text: String = ""
let timer = Timer.publish(every: 1, on: .main, in: .common).autoconnect()
@State var color: Color? = .white
var body: some View {
TextField("Text...", text: $text).padding().background(color).onReceive(timer) { _ in
color = predict(for: text)?.color
print(color)
}
}
}
But the problem of not updating the view still persists. In prints, I discovered a really strange issue: The line of
print(colorKeys)
is always the same.
