When I try downloading xcode 12 from either the appstore or from the developer code portal I get an error that says I dont have enough storage space. But I have over 200 GB of free memory on hard disk. I am unable to run code on my ipad because xcode 12.0 says its not connected, even though it recognises it and its up-to-date. Having been developing software for over 40 years I am finding Apple products are becoming less and less useful because I spend days just trying to sort out the problems they cause with their poor quality control in updates. So does anyone know how to update xcode or make it run code on my ipad?

I am using MKMapView to display a gps track as an MKPolyline. But when in satellite or hybrid view MKMapView hides parts of the track when I zoom in, even when the entire track should be visible. When I change to street view I get the polyline displayed correctly. Is this a bug in MKMapView or is there some way of forcing the line to sit above the map? My guess is it's something to do with the pseudo-3D rendering that projects trees and other objects above the map plane and results in hiding (or rather preventing the rendering of) parts of the polyline. But I haven't found any way to fix this. I am using a Mac OSX Catalina.
