libHarfBuzzSharp.so
libSkiaSharp.so
TextBob

#!/usr/bin/env xdg-open

bash ./build-macos.sh

Resulting package structure:

TextBob.app
    Contents\
        _CodeSignature\
            CodeResources
        MacOS\
            TextBob
            TextBob.dll
            Avalonia.dll
            ...
        Resources\
            TerxtBob.icns (icon file)
        Info.plist
        embedded.provisionprofile

How to create macOS icons file

You can achieve this using the sips command.

First, store your icon as follows:

In an image file of size 1024 x 1024 pixels
In png format
In a file named Icon1024.png

Then execute the following commands

mkdir MyIcon.iconset

sips -z 16 16     Icon1024.png --out TextBob.iconset/icon_16x16.png
sips -z 32 32     Icon1024.png --out TextBob.iconset/icon_16x16@2x.png
sips -z 32 32     Icon1024.png --out TextBob.iconset/icon_32x32.png
sips -z 64 64     Icon1024.png --out TextBob.iconset/icon_32x32@2x.png
sips -z 128 128   Icon1024.png --out TextBob.iconset/icon_128x128.png
sips -z 256 256   Icon1024.png --out TextBob.iconset/icon_128x128@2x.png
sips -z 256 256   Icon1024.png --out TextBob.iconset/icon_256x256.png
sips -z 512 512   Icon1024.png --out TextBob.iconset/icon_256x256@2x.png
sips -z 512 512   Icon1024.png --out TextBob.iconset/icon_512x512.png

cp Icon1024.png TextBob.iconset/icon_512x512@2x.png

iconutil -c icns TextBob.iconset

The result will be a file named TextBob.icns that you can use to add to your .app directory.
