So I've got a simple app that works on the Android emulator and physical Opel phone, but when I deploy to iPhone I getting a bunch of errors. For starters...

Could not resolve assembly Microsoft.VisualStudio.DesignTools.TapContract

Surely a tap gesture should work out of the box?

Here's the full list:

    [0:] An error occurred: 'e_sqlite3'. Callstack: '   at SQLitePCL.SQLite3Provider_e_sqlite3.SQLitePCL.ISQLite3Provider.sqlite3_libversion_number()

    The app has been terminated.

Anyone know how to resolve this? I'm guessing sqlite pcl is the main issue

Update: Here's a demo project that illustrates the issue I'm facing. https://github.com/steveski/MauiEFIssue

You need add a new entitlements file to your .NET Multi-platform App UI (.NET MAUI) app project, and add a new XML file named Entitlements.plist to the Platforms\iOS\ folder of your app project. Then add the following XML to the file:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
</dict>
</plist>

Update: I found a working example, you can refer to it.
