How to set iOS 13 glyphs programmatically [duplicate]

This question already has an answer here:

Starting with iOS 13, Apple is providing a bunch of glyphs which can be used “everywhere you can use an image”.

You can use SF symbols to represent tasks and types of content in a variety of specific places, such as navigation bars, toolbars, tab bars, context menus, and Home Screen Quick Actions. Throughout the rest of your app, you can use a symbol everywhere you can use an image.

Calculated field not updating until edited in UI

I’m trying to test out data binding with XAML and C# as a novice programmer. I have two sliders that are bound to properties and I want to update a TextBox with the sum of the two values of the properties set by the sliders.

I’m using INotifyPropertyChanged and tried changing every property I could find but I can’t get the textbox to update until I edit the textbox, at which point, the textbox updates to the correct value. Using UpdateSourceTrigger=PropertyChanged only updates the textbox as soon as I edit the textbox instead of when I select another element. I’ve tried writing a separate event handler that doesn’t use [CallerNameMember] and uses a specified property but it didn’t seem to change anything.

<Grid>
    <Grid.RowDefinitions>

    </Grid.RowDefinitions>

    <TextBox Grid.Row="0"
             Text="{Binding BoundNumber, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
             FontSize="20"
             FontWeight="Bold"
             AllowDrop="False" />

    <Slider Grid.Row="1"
            Value="{Binding BoundNumber, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
            Maximum="100"
            Minimum="10"
            IsSnapToTickEnabled="True"
            TickFrequency="10" />
    <TextBox Grid.Row="2"
             Text="{Binding BoundNumber2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
             AllowDrop="False" />
    <Slider Grid.Row="3"

            Value="{Binding BoundNumber2, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
            Maximum="100"
            Minimum="10"
            IsSnapToTickEnabled="True"
            TickFrequency="10" />


    <TextBox Grid.Row="4"
            Name="MathBox"
             Text="{Binding QuickMath, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged, NotifyOnSourceUpdated=True}">
           </TextBox>

</Grid>

Version function does not work for JS files in Laravel Mix

I wrote the following code that combined CSS and JS files with the Webpack.mix.js and the correct result, but the version function does not work for the JS file! What can I do to get it right, and both CSS and JS become version?

webpack.mix.js

mix.setPublicPath('/')
    .copy('node_modules/bootstrap/dist/js/bootstrap.js', 'resources/js')
    .copy('node_modules/jquery/dist/jquery.js', 'resources/js')
    .scripts([
        'resources/js/bootstrap.js',
        'resources/js/jquery.js'
    ], 'resources/js/app.js');

mix.sass('resources/sass/app.scss', 'public/css')
    .styles([
        'public/css/app.css',
        'public/css/myCss.css'
    ], 'public/css/all.css')
    .js('resources/js/app.js', 'public/js')
    .version();

mix-manifest.json

{
    "/css/app.css": "/css/app.css?id=35978cdc6a38f7d64fbb",
    "/css/all.css": "/css/all.css?id=eda19119aa76ef087fde"
