You must see a small, black archery icon about our massive, blue circle – it’s the proper strategy, nonetheless it doesn’t search great.

With your preview you’ll see a big black circle fills the readily available display width. That’s a begin, but it really’s not very right – we would like some coloration in there, and ideally introducing just a little House on either aspect so it doesn’t look so restricted.
As much enjoyable as archery is, this application actually has to recommend a random activity to people rather than normally demonstrating the same factor. That means adding two new Homes to our see: a person to shop the assortment of attainable activities, and 1 to show whichever 1 is presently remaining advised.
To finish up our initial go at this user interface, we could incorporate a title at the top. We have already got a VStack that permits us to situation sights a person higher than the opposite, but I don’t want the title inside there too due to the fact in a while we’ll be adding some animation for that Portion of our monitor.
The problem right here is usually that we’ve informed SwiftUI our person interface will have two views inside of – the circle plus some text – but we haven’t advised it how to rearrange them. Do we wish them side by side? Just one earlier mentioned the opposite? Or in Another style of format?

Of course, we make use of a font great site modifier to regulate the icon’s measurement – SF Symbols such as this one particular routinely scale with the remainder of our text, which makes them definitely versatile.
On the correct-hand facet of Xcode, you’ll see a Dwell preview of that code managing – in the event you create a improve to your code about the left, it will surface during the preview straight absent. If you're able to’t see the preview, follow these Guidance to empower it.
In lieu of utilizing a fastened font read this measurement, that utilizes one of SwiftUI’s inbuilt Dynamic Kind sizes referred to as .title. This suggests the font will improve or shrink depending upon the user’s settings, which is often a good suggestion.
