Render Images on iOS 14 Widgets

Question

I\'m developing a iOS 14 Widget extension.

I have 3 images to show in loop and creating a Timeline to show those images.

func getTimeline(in context: Conte         


        

Answer 1

Constucting timeline you need to specify explicit entry date for each entry. The policy parameter is for recreating next timeline.

So your getTimeline should look like

func getTimeline(in context: Context, completion: @escaping (Timeline<Entry>) -> ()) {
    var entries: [ImageEntry] = []
    let currentDate = Date()

    for i in 1 ..< 4 {
        let imageNumber = String(i)
        let currentImage = "image_" + imageNumber
        let entryDate = Calendar.current.date(byAdding: .minute, value: (i-1)*5, to: currentDate)!
        let entry = ImageEntry(date: entryDate, image: currentImage)
        entries.append(entry)
    }

    let timeline = Timeline(entries: entries, policy: .atEnd)
    completion(timeline)
}
