Xcode 12.5 troubleshooting guide (RN 0.61/0.62/0.63/0.64)

[kelset]

Hey folks.

This issue wants to be a follow up to https://github.com/facebook/react-native/issues/31179; that issue has become really long so opening a new one to try and reduce the noise and confusion around it.

Here is how to fix the Xcode 12.5 iOS build breaks with errors related to "atomic_wait_until is unavailable" (and similar messages).

(sidenote: make sure you are using cocoapods 1.10.x)

If you are on 0.61

Note well: this has only been tested by a few members of the community, not by me, so I can't ensure it will work.

If you are still using RN 0.61, you can refer to this comment https://github.com/facebook/react-native/issues/28405#issuecomment-840914650 from @edgarbonillag.

If you are on 0.62

1. add this line to your podfile (or modify it if you already had it):

   use_flipper!({'Flipper' => '0.75.1', 'Flipper-Folly' => '2.5.3', 'Flipper-RSocket' => '1.3.1'})

2. change your package.json react-native dependency to

   "react-native": "0.62.3"

3. do all the classic necessary cleans (node_modules, caches, pod folders, etc)(react-native-clean-project is your ally) then do yarn install and a pod install --repo-update (if pod install fails on an error about a Flipper package, just remove the relevant lines from the podfile.lock and run the pod install again)

If you are on 0.63

Note well: you need to be on latest 0.63.x release, at the time of writing 0.63.3.

If you are on 0.63, you are in luck! You just need to add this line to your podfile (or modify it if you already had it):

use_flipper!({'Flipper' => '0.75.1', 'Flipper-Folly' => '2.5.3', 'Flipper-RSocket' => '1.3.1'})

Then properly clean your caches (react-native-clean-project is your ally), remove pods folder and do a pod install --repo-update.

This should be enough for you to get Xcode 12.5 to work.

If you are on 0.64

1. (optional) check your podfile.lock and make sure that Flipper is on 0.75 or higher, and Flipper-Folly is 2.5.3 or higher; if not, add this line to your podfile (or modify it if you already had it):

   use_flipper!({'Flipper' => '0.75.1', 'Flipper-Folly' => '2.5.3', 'Flipper-RSocket' => '1.3.1'})

2. change your package.json react-native dependency to:

   "react-native": "0.64.1" // or higher

3. do all the classic necessary cleans (node_modules, caches, pod folders, etc)(react-native-clean-project is your ally) then do yarn install and a pod install --repo-update (if pod install fails on an error about a Flipper package, just remove the relevant lines from the podfile.lock and run the pod install again)

These scenario have all been tested and ✅ so if you are still experiencing issues, it's likely that it's caused by some local configuration getting in the way. If that's the case, please refer to this comment by @smadan.

If none of the above helped you, and you can reproduce your issue consistently - even on a freshly init'd project, then post a comment below with how to repro so that this can be investigated further.

[xclidongbo]

one of Flipper-Folly `s dependencies is "OpenSSL-Universal" . version: '1.1.180' is incompatible with 'libssl.a' old version. when I run app, it always crashes with EXC_BAD_ACCESS in Flipper.

How can I fix it?

[kelset]

@xclidongbo I think that error is caused by cocoapods, make sure you are on latest

[xclidongbo]

@xclidongbo I think that error is caused by cocoapods, make sure you are on latest

cocoapods version is 1.10.1

[nphivu414]

Tried everything for 0.64.1 on XCode 12.5, still no luck. The build keeps failing consistently due to something with FBSDK:

** BUILD FAILED **

The following build commands failed:

(5 failures)

What's strange is the x86_64 part of the error seems to refer to a problem with M1 MacBooks, but I'm on a MacBook Air 2020 (the Intel version, not the M1). Does anyone else know how to resolve this by any chance?

I got the same problem with my iMac 2017 and this solution works for me: https://github.com/facebookarchive/react-native-fbsdk/issues/794#issuecomment-695217977

[ithustle]

RN 0.64.2, after activated hermes on iOS and no luck.

Pods/Headers/Private/RCT-Folly/folly/synchronization/DistributedMutex-inl.h:1051:5: 'atomic_notify_one<unsigned long>' is unavailable

[yoojeen126]

Still build faild on RN 0.63.2, even clean react native project done.

[gmonte]

I created a new project from react-native cli today (react native 0.64.2) and the command react-native run-ios is not working.

error Failed to build iOS project. We ran "xcodebuild" command but it ex
ited with error code 65. To debug build logs further, consider building 
your app with Xcode.app, by opening appTest.xcworkspace.
Command line invocation:
    /Applications/Xcode.app/Contents/Developer/usr/bin/xcodebuild -works
pace appTest.xcworkspace -configuration Debug -scheme appTest -destinati
on id=4B4D293F-C0EB-44FC-B356-4C4E2D794B9A

Well, I tried run the project directly on xcode and it works! But running with react-native cli it fails again. All solutions above does not fix this problem to me.

My environment: MacBook Pro Intel - macOS 11.4 cocoapods 1.10.1 xcode 12.5 - iOS 14.5 react-native 0.64.2

Enviroment: Macbook Pro M1 Cocoapods 1.10.1 Xcode 12.5 react-native 0.64.2

I've tried both in a Rosetta Terminal and a Native terminal and they both fail the exact same way.

FIXED! brew uninstall coreutils

[oarsoy]

Although XCode 12.5 and M1 processors available since December 2020, what a shameful for React Native community to not be able to solve this problem!

If someone is looking for a solution with current stable version 0.64.2, all you need to do in Podfile;

1. delete react_native_post_install line (I don't know why but this command breaks Xcode building as well)
2. add/update following lines like

...
use_flipper!()
post_install do |installer|
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end
...

Facebook literally hates Apple ecosystem. They don't even test with Xcode anymore before releasing new versions. Each versions have different bugs. If someone is starting to React Native recently, I definitely suggest Flutter instead of React Native!

[adrianbartyczak]

Tried to build a new project on Xcode 13 beta. I get this error message:

[oarsoy]

Tried a new project on Xcode 13 beta. I get this error message:

There are some bugs https://github.com/facebook/react-native/issues/31480#issuecomment-858079368

I didn't try yet with Xcode 13 but the solution in Xcode 12.5 with current stable version 0.64.2, all you need to do in Podfile;

1) delete react_native_post_install line (this command breaks Xcode building) 2) add/update following lines like

...
use_flipper!()
post_install do |installer|
installer.pods_project.build_configurations.each do |config|
config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
end
end
...

And after this don't forget to run "pod install".

[adrianbartyczak]

I tried making those changes, but now I get a syntax error:

[Kaihuang724]

@adrianbartyczak It looks like you're missing an end statement for your installer.pods... block. It should look something like this:

use_flipper!({'Flipper' => '0.85.0'})
   post_install do |installer|
     installer.pods_project.build_configurations.each do |config|
         config.build_settings["EXCLUDED_ARCHS[sdk=iphonesimulator*]"] = "arm64"
     end
     flipper_post_install(installer)
   end
end

[kelset]

@adrianbartyczak @Kaihuang724 @oarsoy could I kindly ask you to create a new issue to talk about Xcode 13 related issues? I'm slightly concerned issues not strictly related to the workaround described in this post will surface and it'd be better to track them properly.

Sure, no problem. Just FYI, though, I didn't try on Xcode 13 but could never get the workaround to work in 12.5. I ended up downgrading to 12.4

[adrianbartyczak]

Hey @kelset, sure. I didn't realize the issue was different enough for a new thread, so I'll create one.

@Kaihuang724 I tried your fix for the syntax error, and it fixed it, however when I build the app, I still get the same error.

3. add_flipper_pods

@rbackhouse ... I have RN version 0.62.0 and tried your solution but I had no luck. Below is the error message that I get.

Any suggestions on this?

[rbackhouse]

@Base29 My podfile changed to this which yours has commented out

require_relative '../node_modules/react-native/scripts/autolink-ios'

Not sure if that's the cause

[suprith-s-reddy]

I have the same issue, and I use xcode 12.5, and react-native 0.63.4 and even after trying all the fixes still does not work.

[Jexim]

As for me for react-native 0.64.1 helped these steps: 1) Add to the end of Podfile function find_and_replace :

...
def find_and_replace(dir, findstr, replacestr)
  Dir[dir].each do |name|
      text = File.read(name)
      replace = text.gsub(findstr,replacestr)
      replaced = text.index(replacestr)
      if replaced == nil && text != replace
          puts "Fix: " + name
          File.open(name, "w") { |file| file.puts replace }
          STDOUT.flush
      end
  end
  Dir[dir + '*/'].each(&method(:find_and_replace))
end

2) Change block post_install do |installer| to this:

post_install do |installer|
    flipper_post_install(installer)

    # Fix atomic_notify_one bug for XCode 12.5
    find_and_replace("Pods/RCT-Folly/folly/synchronization/DistributedMutex-inl.h", "atomic_notify_one(state)", "folly::atomic_notify_one(state)") 
    find_and_replace("Pods/RCT-Folly/folly/synchronization/DistributedMutex-inl.h", "atomic_wait_until(&state, previous | data, deadline)", "folly::atomic_wait_until(&state, previous | data, deadline)")
end

3) Find and remove strings $(TOOLCHAIN_DIR)/usr/lib/swift-5.0/$(PLATFORM_NAME) from project.pbxproj file. 4) Add empty swift file to ios project by xCode. 5) Remove folder ios/Pods clear caches, clean build folder in xCode. 6) Install pods and run the project.

change your package.json react-native dependency to "react-native": "0.62.3"

@rbackhouse ... does changing the RN version to 0.62.3 require significant updates to various files of the project? Or did facebook made it easy to update the version of react native ? I remember I use this tool to help me upgrade the RN version https://react-native-community.github.io/upgrade-helper/

I will give it a try and get back to you with the results.

[Base29]

@rbackhouse ... issue resolved by following your guidance ... Thanks for the help

[M-HARIS-97]

@smadan Im using RN 62.2. Ur solution not working for me.

[angadp]

I have been following this thread since almost the start. The best solution that I have found is to use XCode 12.4 and add the support files in your XCode.app for the version you want to use. It will even build for 14.6. There are a bunch of open source projects for this. Just search 'device support files xcode' and then the version number of your iPhone. Putting this out there until a permanent solution is found. This is just a workaround for the people facing issues even after doing the above steps.

[oferRounds]

Has anyone was able to build 0.64 + use_frameworks! + Hermes on iOS? getting multiple build failures note: I disabled Flipper, but it still does not build

I am suddenly seeing this "atomic_notify_one" build error in xcode again.

I have tried with my more-updated flipper that has been working...

As well as reverting back to the original fixes for 0.64.1

Edit: after five years of react native development, I can still be a giant idiot. I was opening the wrong workspace (which did not have the appropriate fixes) in xcode. Glad I spent hours doing that this weekend.

For those on Apple Silicon (M1) chips, I think there are extra steps necessary for react-native 0.64.2.

Eventually I got this to work (react-native 0.64.2, xcode 12.5, apple m1, no rosetta). I documented my steps here in case it is helpful to others:

[oferRounds]

@aiba thanks! Would you be to try if your way works also with use_frameworks! + removing Flipper (as they do not work together)?

@oferRounds Any luck with hermes 0.64 + use_frameworks? This I think is blocking? https://github.com/facebook/react-native/issues/31302 @tapz any update?

[chriskrogh]

I'm actually getting a different error on a fresh install (npx react-native init MyApp) with a M1 Mac and "react-native": "0.64.2", when running yarn ios.

objc[32403]: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libauthinstall.dylib (0x1efc73ad8) and /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x117f6c2b8). One of the two will be used. Which one is undefined.

** BUILD FAILED **

gist of output

None of the methods mentioned above resolve this. I'm able to reproduce consistently with both a fresh install and also by following the steps outlined here

It seems like people have gotten this issue for a bunch of reasons in the past like with Flutter and python

Has anyone encountered this before and knows if this is related?

[Yandamuri]

I ma still facing this error after doing as mentioned in the issue description. I ma using RN 0.63.

Can some one help me to get rid of this error?. Thank you.

[heapwalker]

Suggestion at https://github.com/facebook/react-native/issues/31249#issuecomment-811715288 helps solved my issue. I uninstalled nvm and used n instead.

More info: I faced this issue with RN 0.64.2, Xcode 12.5, node 14.15.5 (and with nvm too).

My RN project failed to build ios app, via npx react-native run-ios. But it succeeded in building android app, via npx react-native run-android. Such strange behavior has occurred for some weeks, probably since after I upgraded Xcode.

I have followed all steps under section "If you are on 0.64" on first post of this issue (except I am using RN 0.64.2 rather than 0.64.1). But no luck, it still failed to build ios app.

Lastly I see https://github.com/facebook/react-native/issues/31249#issuecomment-811715288 . Remembering I did see error messages coming out from npx react-native run-ios:

...
nvm is not compatible with the "npm_config_prefix" environment variable: currently set to "/usr/local"
Run `unset npm_config_prefix` to unset it.
...

(I tried many times running such unset npm_config_prefix but still no success).

Then I tried uninstalling the nvm on my machine (falling back to default node). And then npx react-native run-ios works perfectly! 😃😃

p.s.

• I follow here to uninstall nvm only; without modifying /node_modules/react-native/scripts/find-node.sh.
• As I really need different node versions for different projects, I install the package n instead. Doing so does not harm building RN ios app.

[xiongemi]

how about RN 0.65?

[kelset]

@xiongemi 65 should work out of the box, it did during our testing

[tiennguyen1293]

same issue, when i run npx react-native run-ios on command line. with XCode the build is successfully

I use 0.65-rc.3 and I run the xcode command code: xcodebuild -workspace App2.xcworkspace -scheme App2 -configuration Debug -sdk iphonesimulator -derivedDataPath ./build -quiet

@xiongemi: What's your target iOS version? It doesn't look like thread_local was added until iOS 9.

[xiongemi]

@xiongemi: What's your target iOS version? It doesn't look like thread_local was added until iOS 9.

in my podfile, I have platform :ios, '11.0'

this iso target is from RN 0.65, right? https://raw.githubusercontent.com/react-native-community/rn-diff-purge/release/0.65.0-rc.3/RnDiffApp/ios/Podfile

[tido64]

It would be great if you could upload a minimal repro for us. As kelset mentioned earlier, we did not see this issue during testing.

[flora8984461]

Wondering if anyone using stripe? I am on M1 device, Xcode 12.5, RN 0.64.1 and keep getting

fatal error: module map file '/<path>/DerivedData/<AppName>-bruuceewkpsieogndskuohenymiu/Build/Products/Debug-iphonesimulator/Stripe/Stripe.modulemap' not found

And I think it's kinda related with Xcode and RN. Any help is really appreciated, thanks!

this is repo i used. it is just a out-of-box project I generated using react native cli. I run the command under ios folder: xcodebuild -workspace reactNativeApp.xcworkspace -scheme reactNativeApp -configuration Debug -sdk iphonesimulator -derivedDataPath ./build -quiet and I got this error:

@xiongemi I HAVE NOT NESTED IT: I would start by fixing warnings. Look like You have IPHONEOS_DEPLOYMENT_TARGET set to 8 and not to 9. Since thread_local is supported since IOS 9, so it seems like that should lead to fixing this problem https://github.com/measurement-kit/measurement-kit/commit/9362ad10eac9d6a988dfe429aea5eea28064d67a

i do have it set ios target in xcode:

I run xcodebuild -showBuildSettings | grep IPHONEOS_DEPLOYMENT_TARGET:

DEPLOYMENT_TARGET_CLANG_ENV_NAME = IPHONEOS_DEPLOYMENT_TARGET
    DEPLOYMENT_TARGET_LD_ENV_NAME = IPHONEOS_DEPLOYMENT_TARGET
    DEPLOYMENT_TARGET_SETTING_NAME = IPHONEOS_DEPLOYMENT_TARGET
    IPHONEOS_DEPLOYMENT_TARGET = 11.0

do you mean I have to add delete 'IPHONEOS_DEPLOYMENT_TARGET' to Podfile? I have also tried config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'

  post_install do |installer|
    react_native_post_install(installer)
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end

i got a different error when I run xcodebuild -workspace reactNativeApp.xcworkspace -scheme reactNativeApp -configuration Debug -sdk iphonesimulator -derivedDataPath ./build -quiet:

@xiongemi no, my mistake, I apologize. You seem want Your target to be 11, so set 11. Not 9. :)

@xiongemi no, my mistake, I apologize. You seem want Your target to be 11, so set 11. Not 9. :)

do you mean add config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'? I have tried:

installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
