• platform_type
• target_apple_env
• XcodeProperties
• XcodeVersionConfig

apple_host_system_env

dict apple_common.apple_host_system_env(xcode_config)

Returns a dict of environment variables that should be set for actions that need to run build tools on an Apple host system, such as the version of Xcode that should be used. The keys are variable names and the values are their corresponding values.

Parameters

Parameter	Description
xcode_config	required A provider containing information about the Xcode configuration.

apple_toolchain

unknown apple_common.apple_toolchain()

Utilities for resolving items from the apple toolchain.

dotted_version

DottedVersion apple_common.dotted_version(version)

Creates a new DottedVersion instance.

Parameters

Parameter	Description
version	string; required The string representation of the DottedVersion.

platform

struct apple_common.platform

An enum-like struct that contains the following fields corresponding to Apple platforms:

• ios_device
• ios_simulator
• macos
• tvos_device
• tvos_simulator
• visionos_device
• visionos_simulator
• watchos_device
• watchos_simulator

These values can be passed to methods that expect a platform, like XcodeVersionConfig.sdk_version_for_platform.

platform_type

struct apple_common.platform_type

An enum-like struct that contains the following fields corresponding to Apple platform types:

• ios
• macos
• tvos
• visionos
• watchos

These values can be passed to methods that expect a platform type.

target_apple_env

dict apple_common.target_apple_env(xcode_config, platform)

Returns a dict of environment variables that should be set for actions that build targets of the given Apple platform type. For example, this dictionary contains variables that denote the platform name and SDK version with which to build. The keys are variable names and the values are their corresponding values.

Parameters

Parameter	Description
xcode_config	required
platform	required

XcodeProperties

Provider apple_common.XcodeProperties

The constructor/key for the XcodeVersionProperties provider.

If a target propagates the XcodeVersionProperties provider, use this as the key with which to retrieve it. Example:

dep = ctx.attr.deps[0]
p = dep[apple_common.XcodeVersionProperties]

XcodeVersionConfig

Provider apple_common.XcodeVersionConfig

The constructor/key for the XcodeVersionConfig provider.
