xCode fails to build new react-native init project due to 'library not found for -lDoubleConversion'

[shannonjensen]

I have initiated a new react-native app with the react-native cli (react-native init newproject). The build works if I then run react-native run-ios but if I open the project in xcode (via the .xcodeproj file in the ios folder) then the build fails due to 'library not found for -lDoubleConversion'

React Native version:
System:
OS: macOS 10.14.5
CPU: (4) x64 Intel(R) Core(TM) i5-7360U CPU @ 2.30GHz
Memory: 28.45 MB / 8.00 GB
Shell: 5.3 - /bin/zsh
Binaries:
Node: 12.5.0 - /usr/local/bin/node
Yarn: 1.16.0 - /usr/local/bin/yarn
npm: 6.9.0 - /usr/local/bin/npm
Watchman: 4.9.0 - /usr/local/bin/watchman
SDKs:
iOS SDK:
Platforms: iOS 12.2, macOS 10.14, tvOS 12.2, watchOS 5.2
IDEs:
Xcode: 10.2.1/10E1001 - /usr/bin/xcodebuild
npmPackages:
react: 16.8.6 => 16.8.6
react-native: 0.60.0 => 0.60.0
npmGlobalPackages:
react-native-cli: 2.0.1
react-native-log-ios: 1.0.1

Steps To Reproduce

1. react-native init newproject
2. open ios/newproject.xcodeproj in xcode and build

Describe what you expected to happen:

Build to fail with warning "library not found for -lDoubleConversion"

Please try this. It's work for me in error which I am getting in installing pods.
sudo xcode-select -switch <path/to/>Xcode.app

[irshadpc]

@shannonjensen Look like your project never run the 'pod install' command.

Do the below steps

1. go to ios/
2. run 'pod install' or 'pod update'
3. open ios/newproject.xcworkspace

[shannonjensen]

Thank you @irshadpc.

I followed those steps and am still getting the same error.

I uninstalled and reinstalled cocoapods previously. I ran pod install and then pod update in the ios directory and it looks like everything went as it should, no errors or warnings. But the xcode build still fails while react-native run-ios works fine.

@shannonjensen Can you please share the pod file.

[shannonjensen]

Thank you @irshadpc

@shannonjensen Look like your 'podfile' and 'podfile.lock' are same. I don't know why it happens. Can you please share the code.

[Moneling]

I had this problem.
i resolve this problem is open the *.xcworkspace with xcode ,not the *.xcodepro.
try it.

Ah, sorry @irshadpc, my mistake. The podfile.lock is:

@shannonjensen Please update your cocoapods and run the pod update command. Let me see what happens.

[xJkit]

Due to the fact that DoubleConversion is a third-party library, I think you should open your project with .xcworkspace rather than .xcodeproj.

[CompSciGuy777]

I am having the same problem, only when I try and build the tvOS build of my app in Xcode. I can build the mobile version through the CLI and through Xcode but as soon as I try and target the tv-OS simulator. Things I noticed as I was looking through the project/ios files:

• the tvOS sub-folder didn't have a copy of the project files(appDelegate.m, etc.)...fixed...still the same error

• Other linking under build settings for tvOS project in Xcode...fixed by copying the iOS portion of the podfile to the tvOS portion

• I have tried pod install and pod update at various times
• I have tried deleting my derived data folder

Does anyone know how to get the tvOS to build? Any other Debugging ideas? I can get it to run for iOS but don't know enough about react-native or iOS development to effectively change the device target without some help.

PS: I did open the .workspace, I did try the .proj but got different errors.

[YBDevelopment]

I have the same problem when I try simulate on tv-ios
with this error
ld: library not found for -lPods-reactProject-tvOS

then I found this post when I create the project from his code it works
https://github.com/danilvalov/react-native-appletv
the app runs on tv-os perfect!

@danilvalov thanks

[Fr1kki3]

Temp fix:

right click on products,
select add files,
navigate to ../node_modules/react-native/,
add react project file,
edit scheme,
navigate to build tab,
remove React (missing),
add libReact.a,
move React to top of build order

[sourish]

@shannonjensen Look like your project never run the 'pod install' command.

Do the below steps

1. go to ios/
2. run 'pod install' or 'pod update'
3. open ios/newproject.xcworkspace

This fixed my problem, Thank U.
Can I know from when did pods became mandatory ?
