Realm-cocoa: Missing required architecture arm64 with Realm 5.4.4 against watchOS 7 simulator on Xcode 12

[owenzhao]

Watch Test.zip

Goals

It is said in release note "Add support for the x86_64 watchOS simulator added in Xcode 12.", so I created a new iOS project with a watchOS app. Added Realm by CocoaPods and it couldn't compile.

Run the sample project on simulator.

Expected Results

App ran.

Actual Results

Build failed.

Steps for others to Reproduce

1. create an iOS app.
2. added an watchOS app.
3. create a Podfile and added realm in both targets.
4. pod install
5. open the new workspace file
6. run the app with a iPhone simulator.

Code Sample

Version of Realm and Tooling

Realm framework version: ?
5.3.3

Realm Object Server version: ?

Xcode version: ?
12.0 beta 3 (12A8169g)

iOS/OSX version: ?
iOS 14 simulator

Dependency manager + version: ?

[owenzhao]

The same with Xcode 12 beta 4.

Facing the same issue with Realm 5.3.3, release notes suggested that the issue was fixed.

@tgoyne Perhaps you could shed light on what's causing this to happen or if you're aware of this still being an issue? The errors persist even after removing Realm from the watchOS Extension.

I thought this week and last, Realm employees were on their vacations. As no one answered the issues and nothing was committed to the main branch.

[tgoyne]

Those errors are related to the arm64 simulator added in beta 3, which we have not yet added support for. You'll currently need to add arm64 to the excluded architectures for the simulator only:

[jordimele]

I have the same problem with Xcode 12 beta 6
@tgoyne Is it working to support arm64?
Do you know a possible date when there will be a version of Realm with arm64 support?

[jordimele]

Realm framework version: 5.4.0

Xcode version: Xcode 12 GM (12A7209)

iOS/OSX version: iOS 14 simulator

Project with iOS app & watchOS app

The same problem:

Do you know when it will be resolved?

[jordimele]

Realm framework version: 5.4.1

Xcode version: Xcode 12 (12A7209)

iOS/OSX version: iOS 14 simulator

Project with iOS app & watchOS app

The same problem:

With the latest version released to the store yesterday of Xcode 12 and the latest version of Realm, the same error persists.
Are you working to release a version of Realm that will fix the problem?
It is important to know if a version is going to be released shortly solving the problem or if it is necessary to work with the workaround to exclude arm64 architectures for the simulator because there is no forecast that it will be solved.
Thank you.

[rursache]

v5.4.3 have the same issue, any ETA for the fix?

[jordimele]

Realm framework version: 5.4.4

Xcode version: Xcode 12.0.1 (12A7300)

iOS/OSX version: iOS 14 simulator

Project with iOS app & watchOS app

We have the same problem with the latest version of Realm (5.4.4) and Xcode (Xcode 12.0.1).
@tgoyne Do you know if a version is being worked on that solves this problem?
Thank you.

[leemaguire]

In your target/projects settings add arm64 to the list of excluded architectures.

[owenzhao]

In your target/projects settings add arm64 to the list of excluded architectures.

That won't work at least if you are using other frameworks which depend Realm internally, for example: 'IceCream'.

[leemaguire]

@owenzhao Try this, it may help https://github.com/realm/realm-cocoa/issues/6685#issuecomment-685870573

[jordimele]

@owenzhao Try this, it may help #6685 (comment)

@leemaguire
what you comment is still a workaround.
Working with other frameworks that have the dependency on Realm internally, I have added this configuration in the podspecs:

Pod :: Spec.new do | s |
    s.name = "repo_name"
    ...
    s.watchos.pod_target_xcconfig = {
        'EXCLUDED_ARCHS [sdk = watchsimulator *]' => 'arm64'
    }
end

Configuration is also required in the target / project settings of the application, to add arm64 to the list of excluded architectures.

The question is whether Realm plans to release a fix for that problem and not use the workaround.

[maulik-brt]

It's still happening to me too.
Can anyone help me?

Same issue

[anatoliykant]

Xcode 12.0.1
My corporate (private) framework uses Realm 5.4.7 internally and I still get the following error when linking Podspec file :
ld: in /var/folders/2p/kz5hwvys7pl4gjvpgyww69bh_tbwp3/T/CocoaPods-Lint-20201005-46915-696cd2-MyFramework/Pods/Realm/core/librealmcore-ios.a(array_binary.o), building for iOS Simulator, but linking in object file built for iOS, for architecture arm64 clang: error: linker command failed with exit code 1 (use -v to see invocation)

Guys, tell me if you plan to fix this problem? If so, which version of Realm should this be expected?
Please do not ignore this message and respond. You must respect your developer users! 🧘‍♂️

upd 2020-10-05:
I installed Cocoapods 10.0.0-rc.1, Realm/RealmSwift 10.0.0-rc.1,
used in Podfile

post_install do |installer|
  installer.pods_project.build_configurations.each do |config|
    config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "x86_64 i386"
    config.build_settings["ONLY_ACTIVE_ARCH"] = "YES"
  end
end

and in MyFramework.podspec

spec.user_target_xcconfig = {
  'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => '$(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT)__XCODE_$(XCODE_VERSION_MAJOR))', 'EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64__XCODE_1200' => 'arm64 arm64e armv7 armv7s armv6 armv8'
}
spec.pod_target_xcconfig = {
  'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => '$(EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_$(EFFECTIVE_PLATFORM_SUFFIX)__NATIVE_ARCH_64_BIT_$(NATIVE_ARCH_64_BIT)__XCODE_$(XCODE_VERSION_MAJOR))',
      'EXCLUDED_ARCHS__EFFECTIVE_PLATFORM_SUFFIX_simulator__NATIVE_ARCH_64_BIT_x86_64__XCODE_1200' => 'arm64 arm64e armv7 armv7s armv6 armv8'
}

But none of this helped.

Having exactly the same scenario. Kind of disappointed that this issue has not been solved before the release of iOS14.

I fixed the issue by pushing the podspec files of Realm to our private cocoaspecs repo and adding the EXCLUDED_ARCHS to the spec files of Realm. A workaround I wish did not have to make.

Did I understand correctly that you only created the podspec Realm file in your private repository?
Moreover, you did not clone the Realm and RealmSwift repositories there?!
Could you share the podspec file for Realm?

[dannydeut]

@anatoliykant I only added the spec file to our private cocoa spec repo. No cloning of the actual repo is required. Make sure the source of your private repo is before cdn.cocoapods.org in the podfile of your framework. You might get some warnings about double pods, but these are acceptable until this is fixed the right way. Also had to clear some pod caches...

I'll check it out and post here based on the results.

I'll check it out and post here based on the results.

I checked and it works for me.
The only thing at the end of MyFramework.podspec I had to add the following three lines:

    spec.user_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }
    spec.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64' }

I think we can combine two lines pod_target_xcconfig into one line like this:

spec.pod_target_xcconfig = { 'EXCLUDED_ARCHS[sdk=iphonesimulator*]' => 'arm64', 'VALID_ARCHS' => 'x86_64 armv7 arm64'  }
