This was used in the past to make sure the code can be compiled
with old compilers that do not support using @available. But we
already dropped support for those old compilers, and in many
places already used @available without checking first that it can
be used.
The main change in to use the interface orientation and not the device
orientation. This may be different for example when locking the orientation.
This also changes the way orientation changes are detected using the
documented method. However this means dropping support for iOS 7 as this
method is only available since iOS 8, and alternative methods available in
iOS 7 have been deprecated in iOS 13.
Another change is to properly detect the interface orientation instead of
infering it from the view bounds, which was incorrect on some devices.
This updates the instructions for building the ios7 and tvos backends
using scummvm-ios7-libs-v3, utilizing the Apple XCFramework format for
the pre-compiled libraries.
Using scummvm-ios7-libs-v3 also enables use of the following
features:
- faad
- gif
- mikmod
- mpeg2
- theoradec
- vpx
The introduction of Apple M1 processor, which is based on the arm64
architecture, makes it impossible to use fat static libraries for iOS
and tvOS since building libraries for the simulators targeting the
arm64 architecture conflicts with the iOS and tvOS native arm64
libraries. It's not possible to have two arm64 libraries targeting
different platforms in the same fat library.
Apple resolves this problem with XCFrameworks. Each XCFramework
contain an Info.plist specifying which platforms and architectures it
targets.
The new iOS and tvOS library package, scummvm-ios7-libs-v3, utilize
the XCFramework format and includes pre-compiled libraries for both
iOS and tvOS with corresponding simulator.
Add the option to use XCFramework in create_project by passing the
switch '--use-xcframework'
Implement support to use XCFrameworks for iOS, tvOS and macOS. If not
passing '--use-xcframework' to create_project, legacy behaviour is
applied.
This commit also add support for mikmod for tvOS.
Also added a dedicated debugSound channel for debugging
Fixes include closer conformance to original code (for entering/exiting ESPER and VK), and a change in assigning a track slot to a new track with priority equal to the lowest existing (it will now take the place of the old stored track). Also Music::adjustVolume() now takes the target volume as argument and stores it in the track volume field similar to how Music::adjustPan works.
According to documentation getExternalFilesDir returns the absolute path to application-specific directory
May return null if shared storage is not currently available.
This will not happen for getFilesDir() which returns the internal app path (always guaranteed to be available)
