Add Apple TV OS as a new target to the xcode project creator utility.
Make sure that TV OS specific files are not part of the iOS and macOS
targets and the other way around.
The TV OS project will utilize the same source code files as the iOS
project but will instead use the tvos dist files.
The Apple TV OS requires a different type of storyboard than iOS. Also,
the Info.plist file differ since the tvOS platform doesn't handle
different orientations.
The Apple TV OS also need a different set of icons with different
resolutions more suitable for TV screens.
The application icons are required to be of layered type, which means
that a single PNG file is not accepted as an icon file. The icons must
have at least two layers, hence the ScummVM icon is defined by a back
image with just the background color and a front image with the ScummVM
logo.
The icons are then put together when archiving the application in Xcode
to an Assets.car file. However the linux builds are not building the
application using Xcode. Therefore a pre-compiled Assets.car file
containing the image assets (icons, splash screen etc) is added to the
tvos folder. This file is copied to the application bundle. If the icons
are changed in the future a new Assets.car file has to be compiled. This
can only be done on a computer with Xcode installed. To compile run the
following command in the tvos folder:
xcrun actool ./Images.xcassets --compile build --platform appletvos \
--minimum-deployment-target 9.0 --app-icon AppIcon \
--output-partial-info-plist build/partial.plist \
--launch-image LaunchImage
The partial.plist file generated will show what to add to the Info.plist
and if something must be changed in the ports.mk section for the
tvosbundle.
