My complication code is very similar to that found in the Migrating ClockKit complications to WidgetKit tutorial. Except, I am only interested in displaying the app icon as the complication.
I just cannot get any 'custom' images to display in the simulator, nor on a Watch. Image(systemImage: "") work fine, however.
Does the image need to be re-sized to a specific resolution? The original image is 1024×1024, I have tried re-sizing this down to multiple smaller resolutions with no success.

import Intents
struct Provider: IntentTimelineProvider {
func placeholder(in context: Context) -> SimpleEntry {
SimpleEntry(date: Date(), configuration: ConfigurationIntent())
}
func getSnapshot(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (SimpleEntry) -> ()) {
let entry = SimpleEntry(date: Date(), configuration: configuration)
completion(entry)
}
func getTimeline(for configuration: ConfigurationIntent, in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
var entries: [SimpleEntry] = []
// Generate a timeline consisting of five entries an hour apart, starting from the current date.
let currentDate = Date()
for hourOffset in 0 ..< 5 {
let entryDate = Calendar.current.date(byAdding: .hour, value: hourOffset, to: currentDate)!
let entry = SimpleEntry(date: entryDate, configuration: configuration)
entries.append(entry)
}
let timeline = Timeline(entries: entries, policy: .atEnd)
completion(timeline)
}
func recommendations() -> [IntentRecommendation<ConfigurationIntent>] {
return [
IntentRecommendation(intent: ConfigurationIntent(), description: "Treadmill Assistant")
]
}
}

let date: Date
let configuration: ConfigurationIntent
}
struct Tread_Cadence_ComplicationEntryView : View {
