ComplicationController getLocalizableSampleTemplate gets called multiple times during development

Hello everyone,

I'm having trouble understanding when getLocalizableSampleTemplate() will be called in production apps. During development, this method is called several times a day for me, even if I don't run a new build on my Watch.

My app has several complications updates througout the day using

server.reloadTimeline(for: complication)

but calling reloadtimeline does not necessarily trigger "getLocalizableSampleTemplate()" calls.

Per documentation: https://developer.apple.com/documentation/clockkit/clkcomplicationdatasource/1650686-getlocalizablesampletemplate

"The system calls this method once per supported complication when your extension is installed, and the results are cached"

I have some logs that show the app appears to crash when this method is called in some circumstances. However, I don't get a crash report nor has it ever crashed when the debugger has been active. I'm trying to get a better understanding of this method.

An example last line of log before crash hits this code:

case .circularSmall:
            let localComp = CLKComplicationTemplateCircularSmallSimpleImage()
          
            let imageName = "Complication/Circular"
            let image = UIImage.init(named: imageName)
          
            if image != nil {
              
                localComp.imageProvider = CLKImageProvider.init(onePieceImage: image!)
            }
            else {
            
                handler(nil)
                return
            }
          
            builtComp = localComp
            handler(builtComp)

any insight would be appreciated!
