MAUI iOS调试时WebView显示空白问题求助

问题说明 #

调试MAUI应用时，iOS端WebView显示空白，但部署应用后WebView可正常渲染，Windows端调试无异常。最终需获取页面重定向后的Cookie，需先解决页面渲染问题。本人不熟悉iOS开发，以下是相关配置代码：

XAML代码 #

<ContentPage xmlns="http://schemas.microsoft.com/dotnet/2021/maui"
         xmlns:x="http://schemas.microsoft.com/winfx/2009/xaml"
         x:Class="FreshMaui.Pages.LoginPage"
         Title="LoginPage">
<Grid ColumnDefinitions="*" RowDefinitions="*" WidthRequest="500" HeightRequest="1500">
    <WebView x:Name="WebView"
             Grid.Column="0"
             Grid.Row="0"
     MinimumHeightRequest="1000"
     MinimumWidthRequest="200" 
     VerticalOptions="FillAndExpand" 
     HorizontalOptions="FillAndExpand" Navigated="WebView_Navigated"/>
</Grid>

后台代码（Xaml.cs） #

public LoginPage()
{
    Shell.SetNavBarIsVisible(this, false);
    InitializeComponent();
    WebView.IsVisible = true;
    WebView.Source = "https://[website].com/login.aspx?WL_Type=I&WL_AppId=[appid]&WL_ReturnMethod=FV&WL_Expire=1&ReturnMethod=Get&WL_ReturnUrl=[appurl]://FreshMaui/Pages/LoginPage.xaml?p1=v1";
}

补充信息 #

在Safari中访问该URL时会提示SSL证书不受信任，以下是info.plist配置：
