Bazel rules for creating watchOS applications and bundles.

Rules

watchos_application

Builds and bundles an watchOS Application.

name

A unique name for this target.

app_icons

Files that comprise the app icons for the application. Each file must have a containing directory named *..xcassets/*..appiconset and there may be only one such ..appiconset directory in the list.

bundle_id

The bundle ID (reverse-DNS path followed by app name) for this target.

bundle_name

The desired name of the bundle (without the extension). If this attribute is not set, then the name of the target will be used instead.

deps

A list of targets whose resources will be included in the final application. Since a watchOS application does not contain any code of its own, any code in the dependent libraries will be ignored.

entitlements

The entitlements file required for device builds of this target. If absent, the default entitlements from the provisioning profile will be used.

The following variables are substituted in the entitlements file: $(CFBundleIdentifier) with the bundle ID of the application and $(AppIdentifierPrefix) with the value of the ApplicationIdentifierPrefix key from the target's provisioning profile.

entitlements_validation

An entitlements_validation_mode to control the validation of the requested entitlements against the provisioning profile to ensure they are supported.

executable_name

The desired name of the executable, if the bundle has an executable. If this attribute is not set, then the name of the bundle_name attribute will be used if it is set; if not, then the name of the target will be used instead.

extension

The watchos_extension that is bundled with the watch application.

infoplists

A list of .plist files that will be merged to form the Info.plist for this target. At least one file must be specified. Please see Info.plist Handling for what is supported.

ipa_post_processor

A tool that edits this target's archive after it is assembled but before it is signed. The tool is invoked with a single command-line argument that denotes the path to a directory containing the unzipped contents of the archive; this target's bundle will be the directory's only contents.

Any changes made by the tool must be made in this directory, and the tool's execution must be hermetic given these inputs to ensure that the result can be safely cached.

minimum_os_version

A required string indicating the minimum OS version supported by the target, represented as a dotted version number (for example, "9.0").

platform_type

provisioning_profile

The provisioning profile (.mobileprovision file) to use when creating the bundle. This value is optional for simulator builds as the simulator doesn't fully enforce entitlements, but is required for device builds.

resources

A list of resources or files bundled with the bundle. The resources will be stored in the appropriate resources location within the bundle.

storyboards

A list of .storyboard files, often localizable. These files are compiled and placed in the root of the final application bundle, unless a file's immediate containing directory is named *.lproj, in which case it will be placed under a directory with the same name in the bundle.

strings

A list of .strings files, often localizable. These files are converted to binary plists (if they are not already) and placed in the root of the final bundle, unless a file's immediate containing directory is named *.lproj, in which case it will be placed under a directory with the same name in the bundle.

version

An apple_bundle_version target that represents the version for this target. See apple_bundle_version.


watchos_build_test

Test rule to check that the given library targets (Swift, Objective-C, C++) build for watchOS.

Typical usage:

watchos_build_test(
    name = "my_build_test",
    minimum_os_version = "6.0",
    targets = [
        "//some/package:my_library",
    ],
)

name

A unique name for this target.

minimum_os_version

A required string indicating the minimum OS version that will be used as the deployment target when building the targets, represented as a dotted version number (for example, "9.0").

platform_type

targets

The targets to check for successful build.


watchos_dynamic_framework

Builds and bundles a watchOS dynamic framework that is consumable by Xcode.

name

A unique name for this target.

binary_type

This attribute is public as an implementation detail while we migrate the architecture of the rules. Do not change its value.

bundle_id

The bundle ID (reverse-DNS path followed by app name) for this target.

bundle_loader

This attribute is public as an implementation detail while we migrate the architecture of the rules. Do not change its value.

bundle_name

The desired name of the bundle (without the extension). If this attribute is not set, then the name of the target will be used instead.

codesign_inputs

A list of dependencies targets that provide inputs that will be used by codesign (referenced with codesignopts).

codesignopts

A list of strings representing extra flags that should be passed to codesign.

deps

A list of dependencies targets that will be linked into this target's binary. Any resources, such as asset catalogs, that are referenced by those targets will also be transitively included in the final bundle.

dylibs

This attribute is public as an implementation detail while we migrate the architecture of the rules. Do not change its value.

executable_name

The desired name of the executable, if the bundle has an executable. If this attribute is not set, then the name of the bundle_name attribute will be used if it is set; if not, then the name of the target will be used instead.

exported_symbols_lists

A list of targets containing exported symbols lists files for the linker to control symbol resolution.

Each file is expected to have a list of global symbol names that will remain as global symbols in the compiled binary owned by this framework. All other global symbols will be treated as if they were marked as __private_extern__ (aka visibility=hidden) and will not be global in the output file.

See the man page documentation for ld(1) on macOS for more details.

extension_safe

If true, compiles and links this framework with -application-extension, restricting the binary to use only extension-safe APIs.

frameworks

A list of framework targets (see ios_framework) that this target depends on.

infoplists

A list of .plist files that will be merged to form the Info.plist for this target. At least one file must be specified. Please see Info.plist Handling for what is supported.

ipa_post_processor

A tool that edits this target's archive after it is assembled but before it is signed. The tool is invoked with a single command-line argument that denotes the path to a directory containing the unzipped contents of the archive; this target's bundle will be the directory's only contents.

Any changes made by the tool must be made in this directory, and the tool's execution must be hermetic given these inputs to ensure that the result can be safely cached.

linkopts

A list of strings representing extra flags that should be passed to the linker.

minimum_os_version

A required string indicating the minimum OS version supported by the target, represented as a dotted version number (for example, "9.0").

platform_type

provisioning_profile

The provisioning profile (.mobileprovision file) to use when creating the bundle. This value is optional for simulator builds as the simulator doesn't fully enforce entitlements, but is required for device builds.

resources

A list of resources or files bundled with the bundle. The resources will be stored in the appropriate resources location within the bundle.

stamp

Enable link stamping. Whether to encode build information into the binary. Possible values:

  • stamp = 1: Stamp the build information into the binary. Stamped binaries are only rebuilt when their dependencies change. Use this if there are tests that depend on the build information.
  • stamp = 0: Always replace build information by constant values. This gives good build result caching.
  • stamp = -1: Embedding of build information is controlled by the --[no]stamp flag.

strings

A list of .strings files, often localizable. These files are converted to binary plists (if they are not already) and placed in the root of the final bundle, unless a file's immediate containing directory is named *.lproj, in which case it will be placed under a directory with the same name in the bundle.

version

An apple_bundle_version target that represents the version for this target. See apple_bundle_version.


watchos_extension

umbrella_header

An optional single .h file to use as the umbrella header for this framework. Usually, this header will have the same name as this target, so that clients can load the header using the #import <MyFramework/MyFramework.h> format. If this attribute is not specified (the common use case), an umbrella header will be generated under the same name as this target.
