A fun real world problem I am trying to debug.
iPhone XS crashes when the Map on the MyLocations App is accesed.
This may be an Apple MapKit problem with a specific device. There is no issue when run on an iPhone 6S for example or run on the simulator.
Steps to reproduce the problem:
Download the “iOS Apprentice iOS_Apprentice_v7.0.zip” from raywenderlich.com Download
Unzip download file
In Xcode open “iOS_Apprentice_v7.0/my-locations/Source Code/29-Maps/chapter-29-final/MyLocations.xcodeproj”
Build and run on a iPhone XS (not on the simulator as there is no issue when run on the simulator)
Tag to add a location to the app
At the bottom right of the screen tap “Map”
Xcode indicates the line the app terminates on is “mapView.addAnnotations(locations)” in MapViewController.swift
The crash log on the iphone indicates the app crashed deep in the Apple framework
