我有一个显示网络视图的基本列表。我想添加一个在网页加载时显示的活动指示器。这是我创建的代码。

import SwiftUI
import WebKit

struct WebView: UIViewRepresentable {
    var url: String

    // makeUIView func
    func makeUIView(context: Context) -> WKWebView {

        guard let url = URL(string: self.url) else {
            return WKWebView()
        }

        let request = URLRequest(url: url)
        let wkWebView = WKWebView()
        wkWebView.load(request)
        return wkWebView
    }

    // updateUIView func
    func updateUIView(_ uiView: WKWebView, context: Context) {
    }

}


struct WebView_Preview: PreviewProvider {
    static var previews: some View {
        WebView(url: "https://www.google.com")
    }
}

谢谢你！

我正在尝试制作一个复利计算器应用程序，当我返回复利公式时出现此错误 -> Initializer 'init(_:)' 要求 'Decimal' 符合 'BinaryInteger'

执行复利公式时出现错误： return balance * pow((1 + rate / 100), Int(mounths))

struct CompoundView: View {
@State var accountBalance: Decimal?
@State var percentagePerMounth: Decimal?
@State var numberOfMounths: Decimal?

@State var totalCompoundInterest = " "

var total: Decimal {
    guard let balance = self.accountBalance, let rate = self.percentagePerMounth, let mounths = self.numberOfMounths else {
        return 0
    }
    return balance * pow((1 + rate / 100), Int(mounths))
}
