Apple bundle for framework fails to import

[timofticiuc]

Cheers,

I'm trying to use the examples i've found online to generate an ObjC framework which i can later include in an ObjC project and i keep getting this error: `fatal error: 'ObjcFramework/SampleObjcClass.h' file not found

import <ObjcFramework/SampleObjcClass.h>`

where ObjcFramework is the framework i'm generating with a BUCK file and SampleObjcClass is one of the exported headers

this is the buck file for the main app:

apple_resource(
  name = 'BuckSampleAppResources',
  files = glob(['*.png','*.storyboard']),
  dirs = [],
)

apple_bundle(
  name = 'BuckSample',
  binary = ':BuckSampleBinary',
  extension = 'app',
  info_plist = 'Info.plist',
  deps = [':BuckSampleAppResources'],
)

apple_binary(
  name = 'BuckSampleBinary',
  preprocessor_flags = ['-fobjc-arc'],
  headers = glob([
    '*.h',
  ]),
  srcs = glob([
    '*.m',
  ]),
  deps = ['//ios/BuckSample/ObjcFramework:ObjcFramework'],
  frameworks = [
    '$SDKROOT/System/Library/Frameworks/UIKit.framework',
    '$SDKROOT/System/Library/Frameworks/Foundation.framework',
  ],
)

and this one's for the framework:

apple_library(
  name = 'ObjcDynamicLibrary',
  srcs = glob(['ObjcFramework/*.m']),
  preprocessor_flags = ['-fobjc-arc'],
  exported_headers = ['ObjcFramework/SampleObjcClass.h'],
  visibility = ['PUBLIC'],
  info_plist = 'ObjcFramework/Info.plist',
  #preferred_linkage = 'shared',
  header_path_prefix = 'ObjcFramework',

  frameworks = [
    '$SDKROOT/System/Library/Frameworks/UIKit.framework',
    '$SDKROOT/System/Library/Frameworks/Foundation.framework',
  ],
)

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

To be noted that if i don't wrap the library in a bundle and just leave it to buck to compile it as a static library, it works. however, i need to able to generate a framework for future use Also, here's a repo for the whole example project if anyone wants to take a look over it: https://github.com/timofticiuc/BuckSample

Framework doesn't work currently, because exported headers from apple_library are not propagated up to the bundle. The support for framework started at https://github.com/facebook/buck/pull/1032, and we are currently not actively working on it. Instead, we find another way without frameworks by supporting clang modules https://github.com/facebook/buck/pull/983.

We are discussing about continue our effort on supporting framework after module support, we also heard that Facebook is working on it @Coneko? Maybe we should have a meeting around this thing to make sure we are not duplicating our work.

Thanks dude, thought i was losing my mind. So as i see it, it's either let them link as static libraries or wait for #983 to be merged

[nguyentruongtho]

Yes, I'm breaking up https://github.com/facebook/buck/pull/983 into smaller PRs, the first one is recently merged https://github.com/facebook/buck/issues/1238, and working on following up PRs.

Please read up about modules http://clang.llvm.org/docs/Modules.html, it is a similar concept to framework, and if it fits your case, you should wait for that PR to be merged.

Is it now possible to generate a .framework that can be exported to Xcode app ?

We try to do it like:

load("//Config:buck_rule_macros.bzl", "apple_lib", "apple_pod_lib")
load("//Config:configs.bzl", "info_plist_substitutions")

apple_pod_lib(
    name = "Shared",
    srcs = glob([
        "**/*.swift",
    ]),
        supported_platforms_regex = '^(iphoneos|iphonesimulator).*',
        exported_headers = glob([
            "**/*.h",
        ]),
        swift_version = "4.2",
        deps = [
            "//Frameworks:PromiseKit",
            "//Frameworks:RealmSwift",
            "//Frameworks:AdyenCSE",
            "//Frameworks:BlurKit",
            "//Frameworks:Differ",
            "//Frameworks:Lottie",
            "//Frameworks:nanopb",
            "//Frameworks:netfox",
            "//Frameworks:Nuke",
            "//Frameworks:Protobuf",
            "//Frameworks:Realm",
            "//Frameworks:Starscream",
            "//Frameworks:SwiftyBeaver",
            "//Frameworks:Swinject",
            "//Frameworks:ZXingObjC",
            "//LegacyDependencies/AdidasUINew:AdidasUINew",
            "//LegacyDependencies/TrackingCore:TrackingCore",
            "//LegacyDependencies/AdidasUI:adidasUI",
            "//LegacyDependencies/PhoneNumberKit:PhoneNumberKit",
            "//LegacyDependencies/StoreFinder:StoreFinder",
            "//LegacyDependencies/ConfirmedCore:ConfirmedCore",
            "//LegacyDependencies/CustomerChatCore:CustomerChatCore",
            "//LegacyDependencies/CustomerChatUI:CustomerChatUI",
            ":SharedAssets"
    ],
        link_style = 'shared',
        header_path_prefix = 'ObjcFramework',
)

apple_resource(
    name = "SharedResources",
    visibility = ["PUBLIC"],
    files = glob([
            "**/*.xib",
            "**/*.storyboard",
        ]),
)

apple_asset_catalog(
    name = "SharedAssets",
    visibility = ["PUBLIC"],
    dirs = glob(["**/*.xcassets"]),
)

apple_bundle(
    name = "SharedBundle",
    visibility = [
        "PUBLIC",
    ],
    extension = "framework",
    binary = ":Shared#static",
    product_name = "Shared",
    info_plist = "Info.plist",
        deps = [
        ":SharedResources",
    ],
        info_plist_substitutions = info_plist_substitutions("Shared"),
)

the frameworks gets build, but I can't be imported from Xcode code

[edias]

Is this issue still happening? I'm able to generate a framework (#dwarf-and-dsym,no-include-frameworks) but I'm having issues with headers not being included.

I'm guessing the issue remains?

I'm trying to generate fat frameworks to import on Xcode
