React Native IOS Build CFBundleIdentifier Does not Exist

Question

I have create sample React Native project and following the tutorial as per react native website.

I have try to run the application IOS simulator, its throwing error

Answer 1

Try to add CFBundleIdentifier in the Info.plist as:

 <key>CFBundleIdentifier</key>
<string>org.reactjs.native.example.$(PRODUCT_NAME:rfc1034identifier)</string>

Answer 2

This may happen because of some library files not found.You need to follow some steps That I have done and it is worked perfectly for me. 1.) go to Xcode project -> Target -> select build Phase -> Go to target dependies -> Click on + -> add "react" and press add.

2.) Xcode > Product -> scheme > manage sceme -> click on + button -> targetName(React) -> Okay -> make shared of this by select checkbox under shared column.

3.) Clean your project and try to build, If it is getting some error like "glog/logging.h file not found" or "cofig.h file not found" in Xcode and "CFBundleIdentifier not exist" then do not worry. You are just one step far. This is may occurs if you are missing config.h file, For this you need to update config.h file. For this

4.) follow below steps a.) close your Xcode b.) Open terminal with the project (Or you can directly left click your project and drag your folder to closed terminal, [It will automatically take the path from your that corresponding folder]) c.) write command

cd node_modules/react-native/third-party/glog-0.3.4/

d.) Run the configure scripted file by the command

./configure

e.) now close terminal and go to terminal with your project root path. now try final run your iOS project by

react-native run-ios

Happy Coding :)

Answer 3

Run the command

react-native upgrade
react-native run-ios

or

react-native run-android

this was solved when am faced this issue

Answer 4

For XCODE 10.0, I did two things

1) check out this answer which basically says Go to File -> Project settings

Click the Advanced button

Select "Custom" and select "Relative to Workspace" in the pull down

Change "Build/Products" to "build/Build/Products"

2) If (1) doesn't work for you then open your project from xcode go to project navigator and select your project name --> go to info --> use debug for command-lines builds.

do this

3) go to terminal and react-native run-ios

Answer 5

In my case, just delete the build directory, Pods directory, node_modules directory and running yarn install, pod install and npx react-native run-ios solves the issue.
