2.0.0-rc1

What's Changed

Breaking Changes

• The swift_module= tag on cc_library targets no longer does anything, and the swift_c_module rule was removed: #1191 and #1224
  • Use the new swift_interop_hint aspect hint instead
  • There were also some changes to how the apple_common.Objc provider is handled (e.g. d68b214)
• The deprecated swift proto library rules were removed: #1193
• The Bzlmod module.compatibility_level was increased: #1214
  • If you ruleset can support both pre-2.0 and post-2.0 rules_swift, please set bazel_dep.max_compatibility_level = 2 instead of bumping your minimum supported version of rules_swift
• The swift.disable_system_index feature is now enabled by default: #1252
• Removed swift.emit_symbol_graph feature: #1229
  • Use the new swift_symbol_graph_extract rule
• Removed the swift.use_response_files feature: #1275
• Removed the swift.bundled_xctests feature: #1272
• Removed the implicit output from swift_library: #1260
• Moved swift_usage_aspect and SwiftUsageInfo from rules_swift into rules_apple: #1223
• Manually specifying the -index-store-path flag while also using the swift.index_while_building is no longer supported: #1248
• It is now an error to specify both swiftinterface and swiftmodule in swift_import: #1253

Deprecations

• Moved rules and other build definitions into their own public files and deprecated the umbrella swift.bzl and proto.bzl files: #1231, #1236, and #1255
  • Please update your load statements as the swift.bzl file will be removed in the next major release

Other changes

• Added support for symbol graph extraction with the swift_symbol_graph_extract rule: #772, #1195, #1246, #1270, and #1271
• Added support for the fdo_instrument_order_file feature: #1251
• Added the swift.add_target_name_to_output feature, which allows multiple targets in a package to produce the same module name in the same build: #1098 and #1217
• Added the swift.thin_lto and swift.full_lto features to enable LTO: #1208
• Added the swift.propagate_generated_module_map feature to propagate the generated module map: #1212
• Added the swift.headers_always_action_inputs feature which causes all headers to always be included as inputs to SwiftCompile actions, even when using explicit modules: #1249
• Added an API to compile a .swiftinterface file into a .swiftmodule: #1250
• Added an XCTest observer to swift_test targets that generates a JUnit-style XML log at the path in the XML_OUTPUT_PATH environment variable defined by Bazel: #1222, #1242, #1263, and #1273
• Added a discover_tests attribute to swift_test: #1259, #1266, #1273, and #1274
• Added a mechanism to provide a list of protocol names for constant value extraction: #1170
• Added a swift_common.get_toolchain helper function: #1226, #1257, and #1258
• resource_set is now defined for SwiftCompile actions: #1241
• Swift compiler sandboxing is now disabled when using Xcode 15.3+, which fixes nested sandboxing errors: #1206
• We now correctly add .swiftmodule directories to the search path: #1245
• We now correctly calculate the minimum supported OS when calculating the target triple for 'arm64-apple-ios-simulator' targets: #1247
• The new driver is now used on Xcode 14+ since it contains the fixes in swiftlang/swift-driver#1036: #1268
• Removed some no-longer-relevant "supports X" features: #1267
• Fixed LLDB expr evaluation for swift_{binary,test} targets only containing Swift in their srcs: #1269

This release is compatible with Bazel 6.x LTS, 7.x LTS, and 8.x rolling releases.

1.14.0

What's Changed

• Fix clang discovery when compiler isn't named clang
• Update swift_test to fail if it doesn't execute any tests, thanks @jszumski!
• Add --@build_bazel_rules_swift//swift:copt and --@build_bazel_rules_swift//swift:exec_copt flags to replace --swiftcopt and --host_swiftcopt in the future (--host_swiftcopt is already removed from bazel @ HEAD). The easiest migration path is to use --flag_alias=swiftcopt=@build_bazel_rules_swift//swift:copt --flag_alias=host_swiftcopt=@build_bazel_rules_swift//swift:exec_copt
• Fix bazel @ HEAD support removing linking info from the objc provider
