I would like to create a complication for watchOS 3 that will simply launch my App. I have used XCode to create the ComplicationController:
class ComplicationController: NSObject, CLKComplicationDataSource
{
// MARK: - Timeline Configuration
func getSupportedTimeTravelDirections(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimeTravelDirections) -> Void) {
handler([.forward, .backward])
}
func getTimelineStartDate(for complication: CLKComplication, withHandler handler: @escaping (Date?) -> Void) {
handler(nil)
}
func getTimelineEndDate(for complication: CLKComplication, withHandler handler: @escaping (Date?) -> Void) {
handler(nil)
}
func getPrivacyBehavior(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationPrivacyBehavior) -> Void) {
handler(.showOnLockScreen)
}
// MARK: - Timeline Population
func getCurrentTimelineEntry(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimelineEntry?) -> Void) {
// Call the handler with the current timeline entry
handler(nil)
}
func getTimelineEntries(for complication: CLKComplication, before date: Date, limit: Int, withHandler handler: @escaping ([CLKComplicationTimelineEntry]?) -> Void) {
// Call the handler with the timeline entries prior to the given date
handler(nil)
}
func getTimelineEntries(for complication: CLKComplication, after date: Date, limit: Int, withHandler handler: @escaping ([CLKComplicationTimelineEntry]?) -> Void) {
// Call the handler with the timeline entries after to the given date
handler(nil)
}
// MARK: - Placeholder Templates
func getLocalizableSampleTemplate(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTemplate?) -> Void) {
// This method will be called once per supported complication, and the results will be cached
handler(nil)
}
}
and added images for the Circular, Modular and Utilitarian assets. But when I run the Watch App I cannot select my complications for a Watch face. What do I still need to do?
Thanks

These code changes are required:
func getSupportedTimeTravelDirections(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimeTravelDirections) -> Void)
{
handler([])
}
func getCurrentTimelineEntry(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTimelineEntry?) -> Void)
{
if complication.family == .circularSmall
{
let template = CLKComplicationTemplateCircularSmallRingImage()
template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Circular")!)
let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
handler(timelineEntry)
} else if complication.family == .utilitarianSmall
{
let template = CLKComplicationTemplateUtilitarianSmallRingImage()
template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Utilitarian")!)
let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
handler(timelineEntry)
} else if complication.family == .modularSmall
{
let template = CLKComplicationTemplateModularSmallRingImage()
template.imageProvider = CLKImageProvider(onePieceImage: UIImage(named: "Modular")!)
let timelineEntry = CLKComplicationTimelineEntry(date: Date(), complicationTemplate: template)
handler(timelineEntry)
} else {
handler(nil)
}
}
func getLocalizableSampleTemplate(for complication: CLKComplication, withHandler handler: @escaping (CLKComplicationTemplate?) -> Void)
{
switch complication.family
{
case .circularSmall:
let image: UIImage = UIImage(named: "Circular")!
let template = CLKComplicationTemplateCircularSmallSimpleImage()
template.imageProvider = CLKImageProvider(onePieceImage: image)
handler(template)
case .utilitarianSmall:
let image: UIImage = UIImage(named: "Utilitarian")!
let template = CLKComplicationTemplateUtilitarianSmallSquare()
template.imageProvider = CLKImageProvider(onePieceImage: image)
handler(template)
case .modularSmall:
let image: UIImage = UIImage(named: "Modular")!
let template = CLKComplicationTemplateModularSmallSimpleImage()
template.imageProvider = CLKImageProvider(onePieceImage: image)
handler(template)
default:
handler(nil)
}
}
Plus you need to provide the images as assets in the extension.
