I use Visual Studio Community on a Mac. I am testing the People database app from Xamarin University, course XAM160. The iOS project creates a database here: /Users/(myusername)/Library/Developer/CoreSimulator/Devices/B9981834-C5FA-4711-A063-A90EB9EC59C5/data/Containers/Data/Application/8A1DEF28-6E77-49E9-A288-24FA58B29FE3/Documents/../Library.
But, boy, am I unable to find that path. The (misnamed) Finder displays no Library folder under Users/(myusername). Elsewhere the Finder shows me a Library/Developer folder but there's no CoreSimulator folder under that.
But no question, the database has been created somewhere, because I stored data in it and then retrieved it next time I ran the app in the simulator.
Would appreciate an explanation!
