如何在swift中设置默认标签颜色

import UIKit

extension UILabel {
    override open func awakeFromNib() {
        super.awakeFromNib()
        textColor = .blue // 设置默认颜色为蓝色
    }
}

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    UILabel.appearance().textColor = .blue // 设置所有UILabel的默认颜色
    return true
}

import SwiftUI

struct DefaultLabelStyle: LabelStyle {
    func makeBody(configuration: Configuration) -> some View {
        Label {
            configuration.title
        } icon: {
            configuration.icon
        }
        .foregroundColor(.blue) // 设置默认颜色为蓝色
    }
}

extension LabelStyle where Self == DefaultLabelStyle {
    static var `default`: DefaultLabelStyle { DefaultLabelStyle() }
}

import SwiftUI

struct ContentView: View {
    var body: some View {
        Label("Hello, World!", systemImage: "globe")
            .labelStyle(DefaultLabelStyle()) // 应用自定义样式
    }
}
