How do I link all packages except one using react-native link ?
I want to run it so that every package except react-native-vector-icons links and makes changes in the native files.
I'm not sure how to do this directly but you can, at least for IOS, open the Project's "Build Phases" tab and look in the "Link Binary with Libraries" dropdown, from which you can manually delete the undesired linked library. This won't delete any files, just the link.

I have added the package react-native-fast-image to my react project which intents faster caching to load images based on priority in a faster way. Also, i have manually linked the libraries as stated here:
https://github.com/DylanVann/react-native-fast-image/blob/master/docs/installation-manual.md
But the build fails.
As per error, I think you haven't did a setup into native xCode. Follow the below steps to link into xCode.
In Xcode:
Add FastImage.xcodeproj to Libraries.
Add libFastImage.a to Link Binary With Libraries under Build Phases.
Don't forgot to link before doing the setup.
1) Need to drag from node_modules->react-native-fast-image->ios->FastImage.xcodeproj into under Libraries folder into xcode.
2) Add libFastImage.a into Link Binary with Libraries section.
I can't add the ReactNativeNavigation.xcodeproj file to my projects Libraries. Any ideas on how to get around this? I left click on Libraries then click add files to my project then go into node_module → react-native-navigation → iOS but then I can't click on the Xcode.proj is like a disabled button when I click on it.
I'm using Xcode 9.4.1.

Solution:
Some how (probably my doing) the ReactNativeNavigation was added to the main project folder so I dragged it down to where the Libraries folder was, and the problem was solved. I suggest if you have this issue to search all the folder in your project, because it is probably already added somewhere in the project.

I want to use react-native-youtube but it shows the error Native component for "RCTYouTube" does not exist, i try to find the solution it looks like i have to link the library manually if the library with native code.
But i have no idea with this link talk about Manual linking Step1 https://facebook.github.io/react-native/docs/linking-libraries-ios.html
I use type command create-react-native-app testyoutube to create my react native project, Visual Studio Code is my tool.
I'm not familiar with Xcode. I try to open my project folder testyoutube in Xcode. It will show an alert Could not open file.
If i want to follow Manual linking Step1 what step should i do ?
Here is my folder structure:
Any help would be appreciated. Thanks in advance.
To expand upon Adeel's answer:
Locate the RCTYouTube.xcodeproj at {your project root} /node_modules/react-native-youtube.
Use XCode to open your iOS project's .xcworkspace (or .xcodeproj if .xcworkspace does not exist).
Locate the 'Libraries' folder in the project navigator pane on the left hand side of the window and drag the RCTVideo.xcodeproj file inside it.
Select your project's target from the targets list pane on the inner left hand side of the window then scroll down to the 'Linked Libraries and Frameworks' section.
Click the plus symbol at the bottom of the section and use the search bar to find 'libRTCYouTube.a', select it from the results, and hit the 'Add' button.
Your library should now be linked!
You have two options to link libraries with your Xcode/Android project.
Automatic linking (run in your terminal in the root folder of your react-native project):
react-native link
Manual Setup:
It's actually very simple. Open your react native xcode project (.xcodeproject file) with Xcode.
On the left side you have the project navigator. Drag the Xcode project from react-native-youtube inside the Libraries group.
Project Navigator
Next step is to add the library to you project. Click on the left side on your xcode project in the project navigator. Go to the libraries section and add the RCTYoutube library.
After you have setup everything up, rebuild the project and you are good to go!
What is the purpose of the react-native link command?
Note: from React-Native 0.60.0 linking packages using react-native link has become redundant. Autolink has been added to the React-Native CLI which means that iOS will now use cocoapods and Android will use gradle. You can read more about Autolinking here.
What is react-native link?
react-native link is an automatic way for installing native dependencies. It is an alternative to manually linking the dependency in your project. It works for both Android and iOS.
When linking a project manually the majority of the steps are the same and so using react-native link allows you to install the native dependency with less fuss and without having to type similar code or perform similar actions repeatedly.
However, it should be noted that running react-native link will not always link a package fully, sometimes additional steps are required and you should check carefully with the installation instructions.
Always read the instructions carefully before installing a dependency and linking it.
iOS Considerations
If your project is using CocoaPods and the dependency that you are linking has a .podspec then when you use run react-native link it will update your Podfile. This is instead of adding the files directly to your Xcode project. You will also have to run pod install inside your ios directory otherwise the native dependency won't be fully installed.
Sometimes installing using CocoaPods can cause more issues, and not every dependency needs to be installed with CocoaPods you could always follow the steps that I outlined in this SO answer to stop react-native link adding a dependency to the Podfile, it is not ideal but it is a workaround. Some dependencies require additions to be made to the Podfile, so you should only do this if the dependency doesn't require pods to run.
react-native link or react-native link dependency-name
Should you just use react-native link when linking any dependency or should you be more explicit and use react-native link dependency-name?
From my experience it is better to use react-native link dependency-name. This is due to the fact that react-native link will try to link (or re-link) all the dependencies that can be linked and this can lead to code duplication. Most of the issues that I have experienced have been when the Android native dependency is being linked. I think there has been some headway in stopping this from happening in subsequent updates, but the old adage applies here once bitten, twice shy
Linking good practice
When using react-native link dependency-name you should follow good practice so that you don't get stung. Sometimes dependencies that you try don't work as expected and removing all the code that was added during the linking process can be tricky. (Xcode project files can be a nightmare to go through if you are unfamiliar with them).
This is how I install dependencies and then link them.
Make sure that you are using version control, like git.
Make sure your code is fully committed with no unsaved changes.
Create a new branch, and check it out.
Install your dependency npm i dependency-name
Then link you dependency react-native link dependency-name
Perform any additional installation steps that the dependency requires. See the installation instructions for the dependency.
Check that your code works with the new dependency.
commmit changes and merge the branch.
Manual Linking
If you prefer to link your native dependencies manually then you should either follow the instructions on the dependency's website or you can look at the documentation that react-native provides.
Currently there is only an explanation on how to manually link iOS projects.
Manually linking Android requires you to make changes in the following locations:
settings.gradle
app/build.gradle
MainApplication.java
As always for the exact changes that you should make you should look at the dependency's manual linking instructions.
Do I have to link?
It depends on the dependency that you are using some dependencies use only code written in Javascript, so it is not required to link them, and there is no benefit served by running react-native link dependency-name.
However, if the dependency contains native code then you will have to link. Either manually or by using react-native link dependency-name.
How can I tell if I need to link the dependency?
Firstly you need to check the website, the github repo, or the npmjs.com page for the dependency. There will usually be instructions there telling you whether to link the dependency after you have installed it.
If you cannot find any instructions about linking, you (probably) won't need to link it.
If you are still unsure, check with the dependency maintainer.
Can I just run link anyway?
Yes, you can it won't do anything if there is nothing to link. But always run it with react-native link dependency-name to avoid issues.
When do I run link?
You only run it after you have installed your dependency. I would recommend running it just after you have installed the dependency. You should then check to make sure that it works, before installing any new dependencies so that you can easily debug.
You shouldn't need to run it more than once per dependency.
It doesn't matter how many components or changes to the javascript code that you make it won't affect the linking, as the linking is purely native and components are javascript.
What is autolink?
Autolink is a new feature that is being added to the react-native-cli. You can read more about autolink here.
Autolink replaces react-native-link
Autolinking is a mechanism built into CLI that allows adding a
dependency with native components for React Native to be as simple as:
yarn add react-native-webview
Autolinking is a replacement for react-native link that brings new features (such as ability to easily integrate native dependencies on iOS) and fixes some of the long-standing issues.
Once it is fully implemented it should make adding dependencies with native-code to your project much easier.
Linking native library means that you are going to integrate already implemented module into your application or module which completes your react native's module functionality.
Steps to integrate lib(android):
1) Add package name to new packages() 2) Add dependencies to settings.gradle file and main application's gradle i.e app/gradle file. 3) sync the projects gradle because you made changes in the gradle and it's done.
All manual steps like below you have to perform
1) Go to your project's home dir using cmd.
2) run npm install
3) Thereafter run rnpm link or react-native link
4) see ios folder in your project folder and if you find any pod file then run pod install after navigating into ios folder in cmd.
now instead,
1) Go to your project's home dir using cmd.
2) run npm install
3) Thereafter run rnpm link or react-native link
4) see ios folder in your project folder and if you find any pod file then run pod install after navigating into ios folder in cmd.
When you've installed a library with native content(android or ios) then you need to require linking to the component react-native library.
like this
react-native link react-native-sound-player
When you installed any third party library with native content,you have to link the dependencies in android and ios. react-native link is responsible for including the dependencies in gradlew and pod files.
for suppose you installed react-native-vector-icons package then you have to link in your gradlew files. the new version of react native 0.60 has auto linking.
npm install react-native-vector-icons
react-native link react-native-vector-icons
Thanks for asking this question
if you are working with fonts
react-native link is used for linking the fonts and assets to project
link command is also for linking the libraries to react-native
But now React-native too better so there is no need to link the library
we can use
pos install
npx jetify
it will automatically link the libraries

I tried to remove an iOS8 today view extension from my iOS App in Xcode6, but somehow the extension is still built and always appearing on the device. I removed both the extensions files from the project as well as the build target. I also removed the application multiple times but the widget is still always copied whenever I build the application.
If you want to keep the sourcecode and only remove the today widget:
go to your app target into your project file
select General -> Embedded binaries
remove the TodayWidgetName.appex file with the minus button
do a clean
If you compile or archive you should not see any longer the today widget appearing in the iOS notification center.
I finally found a solution: in the menu go to Product > Clean and the extensions that are not used or built anymore are gone!
Apparently, there is a way of removing embedded binaries from compiled IPA package if you don't want to recompile. Obviously, after altering the package you'll have to resign it.
This is where embedded binaries are placed:
Payload > .app > PlugIns > .appex
I've tried removing the PlugIns and resigning the whole bundle - seems to be working well.
