Unable to import Objective-C module into Swift

See original GitHub issue

I have an objective-C(cocoapod JKBigInteger) project I am trying to import into Swift, though the module is compiling correctly, Swift don’t see it.

error: no such module 'JKBigInteger'

First attempt:

apple_library(
  name = 'JKBigInteger',
  exported_headers = glob([
    'JKBigInteger/*.h',
    'JKBigInteger/LibTomMath/*.h'
  ]),
  srcs = glob([
    'JKBigInteger/LibTomMath/*.c',
    'JKBigInteger/*.m',
  ]),
  visibility = ['PUBLIC'],
)

Second attempt by creating a framework:

apple_library(
  name = 'JKBigIntegerDynamicLibrary',
  srcs = glob([
    'JKBigInteger/LibTomMath/*.c',
    'JKBigInteger/*.m',
  ]),
  preprocessor_flags = ['-fobjc-arc'],
  exported_headers = glob([
    'JKBigInteger/JKBigInteger.h',
    'JKBigInteger/LibTomMath/*.h'
  ]),
  visibility = ['PUBLIC'],
  header_path_prefix = 'JKBigInteger',
  frameworks = [
    '$SDKROOT/System/Library/Frameworks/Foundation.framework',
  ],
)

apple_bundle(
  name = 'JKBigInteger',
  binary = ':JKBigIntegerDynamicLibrary#shared',
  extension = 'framework',
  info_plist = 'JKBigInteger/Info.plist',
  visibility = ['PUBLIC'],
)

Using as dependency in my apple_binary:

apple_binary(
  name = 'BuckDemoBinary',
  deps = [
    ':Assets',
    ':Storyboards',
    '//Pods/RxSwift:RxSwift',
    '//Pods/RxCocoa:RxCocoa',
    '//Pods/RxGesture:RxGesture',
    '//Pods/JKBigInteger:JKBigInteger',
  ],
  preprocessor_flags = ['-fobjc-arc', '-Wno-objc-designated-initializers'],
  srcs = glob([
    'BuckDemo/*.swift',
  ]),
  frameworks = [
    '$SDKROOT/System/Library/Frameworks/UIKit.framework',
    '$SDKROOT/System/Library/Frameworks/Foundation.framework',
  ],
)

This one is same as https://github.com/facebook/buck/issues/1563 and I’m trying to solve it using bridging header with no luck.

I have a rule for Lottie:

# Lottie iOS.
apple_library(
    name='Lottie',
    visibility=['PUBLIC'],
    preprocessor_flags = ['-D', 'PRODUCT_NAME=Lottie'],
    exported_headers=glob([
        CHECKOUT_PATH + '/lottie-ios/lottie-ios/Classes/PublicHeaders/*.h',
    ]),
    headers=glob([
        CHECKOUT_PATH + '/lottie-ios/lottie-ios/Classes/**/*.h',
    ]),
    srcs=glob([
        CHECKOUT_PATH + '/lottie-ios/lottie-ios/Classes/**/*.m',
    ]),
    frameworks=[
        '$SDKROOT/System/Library/Frameworks/UIKit.framework',
    ],
)

Then I add it in another apple_binary rule:

apple_binary(
    name='AppBinary',
    headers=glob([
        os.path.join(APP_SRC, '**/*.h'),
    ]),
    bridging_header='App/Supporting Files/App-Bridging-Header.h',
    preprocessor_flags=['-fobjc-arc', '-Wno-objc-designated-initializers'],
    srcs=PROD_TARGET_FILES,
    deps=[
        '//vendor:Lottie',
    ],
    frameworks=DEFAULT_FRAMEWORKS,
)

In the bridging header I’ve added #import <Lottie/Lottie.h>, but no luck so far.
