I'm building a react native mobile app and getting an error when I build the iOS project.

ld: library not found for -lboost_context

Xcode version is 12.4 and here is a list of dependencies written in package.json file.

"dependencies": {"@react-navigation/native": "^5.9.4","@react-navigation/stack": "^5.14.4","axios": "^0.21.1","react": "17.0.1","react-native": "0.64.0","react-native-camera": "^3.43.6","react-native-gesture-handler": "^1.10.3","react-native-permissions": "^3.0.2","react-native-qrcode-scanner": "^1.5.4","react-native-reanimated": "^2.1.0","react-native-responsive-screen": "^1.4.2","react-native-safe-area-context": "^3.2.0","react-native-screens": "^3.1.1","react-native-tab-view": "^2.15.2","react-native-vector-icons": "^8.1.0","react-navigation": "^4.4.4"  }

I've been looking into different API/SDKs that would be best and easiest to integrate with my React Native iPhone app. This is an internal employee app, that once a form is submitted I would like to automatically print out a label from a thermal printer (e.g. Brother QL1110NWB).

Some options I found are:

React Native:

• https://github.com/christopherdro/react-native-print

Brother SDK:

• https://support.brother.com/g/s/es/htmldoc/mobilesdk/

Apple AirPrint:

• https://developer.apple.com/documentation/uikit/uiprintinteractioncontroller#//apple_ref/doc/uid/TP40010141-CH1-SW34

Does anyone have experience with any of these API/SDKs and can recommend best method for easy integration and be able to print directly without interaction?

Thank you!

I have a React Native app that receives a push notification from my server.When the app is in background and the user open the notification the app prints a label.When the app is in foreground and receives the notification the app immediately prints a label.

I would like to print the label without the interaction of the user when the app is in background.

How can I achieve this?

I was thinking to use Expo Background Fetch but I need to print the label immediately after the notification and with the Expo Background Fetch I could print too late.

Thanks

I have been following this tutorial to set-up Remote Push notifications on my react-native application using react-native-firebase Version 5.2.0. After I configured everything and ran the application I get an error as:

APNS device token not set before retrieving FCM Token for Sender ID ''. Notifications to this FCM Token will not be delievered over APNS. Be sure to re-retrieve the FCM token once the APNS token is set.

Been trying to figure out how to solve this issue but wasn't quite successful.Running on react-native : 0.61.2, react-native-firebase: 5.2.0

Following is my AppDelegate.m

Thanks a lot for your help.

I get the above error when trying to build the project via Xcode.

I know that there are some threads about this issue already, but I tried everything and it is still not working. Cocoapods update, the pre install thing with static linking etc.

My podfile looks like this:

    require_relative '../node_modules/react-native/scripts/react_native_pods'require_relative '../node_modules/@react-native-community/cli-platform-ios/native_modules'platform :ios, '10.0'target 'gymlabs_mobile_client' do  config = use_native_modules!  use_react_native!(    :path => config[:reactNativePath],    # to enable hermes on iOS, change `false` to `true` and then install pods    :hermes_enabled => false  )  target 'gymlabs_mobile_clientTests' do    inherit! :complete    # Pods for testing    permissions_path = '../node_modules/react-native-permissions/ios'    pod 'Permission-PhotoLibrary', :path => "#{permissions_path}/PhotoLibrary"  end  # Enables Flipper.  #  # Note that if you have use_frameworks! enabled, Flipper will not work and  # you should disable the next line.  # use_flipper!()  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['IPHONEOS_DEPLOYMENT_TARGET'] = '10.12'      end    end  endend

I also added the following thing to my Info.plist:

<key>NSPhotoLibraryUsageDescription</key><string>App Name would like access to your photo gallery</string>

It feels like I have searched the whole Internet for it and still dont find a solution, thanks in advance guys!

I recently installed and uninstalled some dependencies, but I reinstalled node modules (removed node_modules folder and ran npm install and have re-installed pods with pod install). Building through the Xcode UI works fine and the app gives no errors, but when I build through the react-native cli using npx react-native run-ios, the build just hangs forever with no error (see screenshot below):

Again, I've reinstalled node modules, reinstalled pods, restarted my computer, tried running on different simulator devices, but no matter what the build hangs everytime. I need to build this way for debugging and this is costing me a lot of time. Any help would be greatly appreciated.

When upgrading to iOS 12.5, I am getting the compile error that: "Application extensions and any libraries they link to must be built with the APPLICATION_EXTENSION_API_ONLY build setting set to YES."

However, I am explicitly setting it to false in my Podfile:

post_install do |installer|  installer.pods_project.targets.each do |target|    target.build_configurations.each do |config|      config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'NO'    end  endend

Because this is required as a work-around for another issue.

If I set config.build_settings['APPLICATION_EXTENSION_API_ONLY'] = 'YES', then I get even more issues.

Does anyone know how to fix this issue?

After reading https://reactnative.dev/docs/environment-setup, I created a react-native project using npx react-native init ***.

It was successful, so, I tried to run the project using npx react-native run-ios, and got the below error:

When I try to create a campaign in amazon pinpoint no eligible endpoints show up in the segment creation section. Even though I have a device successfully receiving push notifications from the test messaging section.

I have implemented iOS push notifications for my react-native app exactly as shown in the documentation (https://aws-amplify.github.io/docs/js/push-notifications). Everything works without any errors on the frontend and the backend. When I run the code:

PushNotification.onRegister((token) => console.log(token)); 

I successfully receive the app token. I can even receive push notifications from the test messaging section by using the token generated from the onRegister function.

However when I try to create a campaign in amazon pinpoint. I cannot get farther than the create segment section because despite there being 6 total endpoints, there are 0 eligible endpoints. Why are my endpoints ineligible? I have tested on a device. I have tested in a simulator. I tried changing the IAM access of my auth and un auth roles to

"mobiletargeting:*"

so that they have full access to pinpoint.

What am I missing? Why are my endpoints ineligible?

In all of the tutorials that I have gone through. The segment automatically recognizes that the test device is eligible. Why is this not working for my project?

I am working on React Native App project where I have to display an interactive bar chart. As shown in attracted screenshot. The app is working on both iOS and Android devices. Where we are currently providing minimal iOS and Android app support as following:

1. Android 4.3.x / Jelly Bean / API level 18 2. iOS 9.0 or later3. iPadOS 9.0 or later.

Requirement:

1. In a bar chart, every bar will be clickable. When the user clicks on any bar, the relative information will be display below the chart accordingly.
2. Suggested chart library should match our minimal app support in both operating systems (iOS & Android).

Current dependencies

Currently, the project is running with the following React framework versions:

1. React Native: 0.63.4
2. React: 16.13.1

How to get rid of this drag action in ios devices react native? It shows white space. It gives the feel of refreshing the screen.

I have a requirement to upload the entire SqLite.db file backup to the cloud from the device.

It is very new to me see this problem which started happening recently. Previously my app used to work fine on the iOS simulator by running this command react-native run-ios. Now I have done a lot of research and made my app run via XCode. But somehow the metro bundler is not linked when the app runs via XCode.

I tried running the app via react-native run-ios and every time I am seeing this error. It is too big to copy paste every error here, but here are some of them:

Undefined symbols for architecture x86_64:"Swift._ArrayBuffer._copyContents(initializing: Swift.UnsafeMutableBufferPointer<A>) -> (Swift.IndexingIterator<Swift._ArrayBuffer<A>>, Swift.Int)", referenced from:      generic specialization <serialized, Swift._ArrayBuffer<Swift.Int8>> of Swift._copyCollectionToContiguousArray<A where A: Swift.Collection>(A) -> Swift.ContiguousArray<A.Element> in libMixpanel-swift.a(AutomaticProperties.o)ld: symbol(s) not found for architecture x86_64clang: error: linker command failed with exit code 1 (use -v to see invocation)** BUILD FAILED **The following build commands failed:        Ld /Users/careerlabsdev/Library/Developer/Xcode/DerivedData/CareerLabs_Elev8-gxcfanteiuxazegkgwkjkrjxbdmw/Build/Products/Debug-iphonesimulator/CareerLabs.app/CareerLabs normal(1 failure)

I have done a lot of things to make it to work. The only success I got here is, while running the command react-native run-ios, it opens up the metro bundler server. After that it fails with giving a 1000 lines of error. I picked the error which had some cream part. Some key words to pick from the error:

• ld: symbol(s) not found for architecture x86_64
• clang: error: linker command failed with exit code 1 (use -v to see invocation)
• Did not understand the word Ld, which is listed under BUILD FAILED

What I did is as follows:

1. Deleting node_modules, Pods. Cleaning the build from XCode. Running npm install and then cd ios && pod install and then ran the command react-native run-ios
2. Deleting Pods, Podfile.lock. Did pod install and then in the root react-native run-ios
3. Doing these:

rm -rf ~/Library/Caches/CocoaPodsrm -rf Podsrm -rf ~/Library/Developer/Xcode/DerivedData/*pod deintegratepod setuppod installcd ..react-native run-ios

4. Restarted the system, and ran the command again react-native run-ios
5. Added arm64 in the Excluded Architecture from XCode. Please note, this enabled me to build and run the app successfully on XCode. But it doesn't get attached to the metro bundler server. Looks like it runs the release mode only.
6. Updated my package react-native-gesture-handler to the latest one which is 1.10.3, to see if that removes my problem. But no luck :(

My Podfile look like this:

  platform :ios, '10.0'  use_flipper!({'Flipper' => '0.81.0'})  post_install do |installer|    flipper_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 am out of options now, and waiting for some insight to be given. It is indeed frustrating to see an error on something which never created a problem. I am using Apple M1 Chip Macbook. Would appreciate any kind of help on this.

Update V1.0

• I have tried commenting down the use_flipper!(), from the /ios/Podfile, and then redid the same things, like removing Pods, Podfile.lock. Running this command, pod update && pod install && cd.. && npm run ios. Ran into multiple issues. God knows what actually the issue is with XCode and React Native on Apple M1.

Update V2.0

I have found some significant places where the developers are complaining about the same. XCode has forced updated my version to 12.5, without my notice. And now XCode is creating a problem with RN Older projects. Here are the supportive links for the same:

• Flipper doesn't build with XCode 12.5 (GitHub)
• Do I need Flipper? (Reddit)

I hope this may give some insight to the developers who are confused like me. Please take a look, and looks like Facebook is fixing it, but don't know when. Have to keep an eye on it :/

I get the error 'Lexical or Preprocessor Issue React/RCTBridgeDelegate.h file not found in AppDelegate.h' when attempting to build and run my react native project in Xcode 12.1.I have tried reinstalling cocoapods (sudo gem install cocoapods) in project directory and pod install in my ios folder but I am still getting the same error. I've also tried adding React to my Xcode scheme but it doesn't seem to be available in the manage schemes. I think this is where my problem is but I'm not sure how I should add React. Is this a folder? And where is it located? In the node_modules folder? I'm still fairly new to react native and Xcode.

I would really appreciate it if someone can please assist me in resolving this.

Thanks.

I would like add custom font family on my React Native App on iOS. I've no problem with Android, but i've an error in iOS :

File name : dinproRegular.ttf

Call in react-native : fontFamily: "dinproRegular" // Test with "Dinpro Regular" too

No result :(

Anyone have idea ?
