iPhone and iPad Notification have not automatically generated

[l260205354]

Xcode version 8.3.3,OS 10.12.6

I use the following command:
"blade -s icon.png -o AppIcon.appiconset -c"
AppIcon.appiconset is a empty directory.
A new Contents.json file and all size icons are automatically generated in AppIcon.appiconset directory . That's greate.
But the iPhone and iPad Notification sizes are still missing.

Then,I use the following command:
"blade -s icon.png -o AppIcon.appiconset -c -t AppIcon.appiconset/Contents.json"
Nothing happened.

But I open the Xcode project, which uses the AppIcon.appiconset above,use the following command again.
"blade -s icon.png -o AppIcon.appiconset -c -t AppIcon.appiconset/Contents.json"

The iPhone Notification and iPad Notification are both automatically generated.

Is there any way to generate all icons (especially notification) without opening Xcode project?
