Hello Apple Forum friends. We launched an application on app store few years back and its live and running. Now we have created an upgraded version of this app independent to old app's xcode project. We have finished developing our first releasable product and are ready to publish on app store but we do not want to publish it as a separate app, instead we want to publish as an update of old app which is available on app store. These two apps now use different bundle id, so is there any possible way to publish it as an update ?

I need an expert to chime in with a solution. I currently find myself with a doubt regarding the Google Map iOS SDK, it's an iOS Front-End Problem. Problem: We need to fetches places around map region. There can be 1000s of places and each place needs to be plotted on map using ground overlay (GMSOverlay). Each place has icon with particular border and marker needs to render both icon and border. Apart from this, each marker is animatable. They can pulsate when they meet certain criteria. Issue we are having: Plotting multiple overlays on map is making app slow. Z-index of the overlay is not working on tap. Even though their visibility is based on z-index, tap action is not performing as expected. I posted the code snippet on the Google Maps iOS Github, check link: https://github.com/googlemaps/maps-sdk-for-ios-samples/issues/118 Here is a video where I describe the slow/stuttering issue in more detail: https://www.youtube.com/watch?v=qJhFrL1QbNg&feature=youtu.be
