apple_platform_type
Describes an Apple "platform type", such as iOS, macOS, tvOS, or watchOS. This is distinct from a "platform", which is the platform type combined with one or more CPU architectures.Specific instances of this type can be retrieved by accessing the fields of the apple_common.platform_type:
apple_common.platform_type.iosapple_common.platform_type.macosapple_common.platform_type.tvosapple_common.platform_type.watchos
Likewise, the platform type of an existing platform value can be retrieved using its platform_type field.
Platform types can be converted to a lowercase string (e.g., ios or macos) using the str function.
