The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0 - React Native, VS Code

Question

Hey Stackoverflow community,

I am completely new to React Native and already struggling in the first step. I have done everything according to this site: https://reactnative.dev/docs/environment-setup

I have installed node and watchman I have X Code running for the simulation I have installed cocoa pods The editor I am using is VS Code and the terminal is iTerm.

I created a test project like described in the doc.

npx react-native init AwesomeProject

After that, I went inside the folder and ran in two different terminals.

npx react-native start

npx react-native run-ios

When I watch people doing this on Youtube it always works, but what I get is the following:

warning: The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.4.99. (in target 'boost-for-react-native' from project 'Pods')

I would be super happy if someone could help me with this problem. I have seen some other posts on Stackoverflow, but nothing helped.

Thank you very much

UPDATE

After I have make I have changed

cd AwesomeProject/ios
a) Comment this line in Podfile
   # use_flipper!()
b) pod install

With running:

npx react-native run-ios

I am getting this error message:

    /bin/sh -c /Users/mw/Library/Developer/Xcode/DerivedData/AwesomeProject-hdnnulyuswlwrafjfjkeikstoeak/Build/Intermediates.noindex/Pods.build/Debug-iphonesimulator/FBReactNativeSpec.build/Script-90F0FABA0342DD788075D851B9320B7C.sh
N/A: version "N/A -> N/A" is not yet installed.

You need to run "nvm install N/A" to install it before using it.

Researching about this error message I came along that it could have something to do with NodeJS, but Node is installed.

Answer 1

You need an additional step :

1) npx react-native init AwesomeProject

2) cd AwesomeProject/ios
   a) Comment this line in Podfile
      # use_flipper!()
   b) pod install

3) cd ..
   npx react-native run-ios

Answer 2

I faced the same issue in an already exisiting project. In this project Flipper is necessary, so commenting it out in the Podfile didn't solved the issue.

This comment with an instruction depending on the React Native version helped me to get the project back running in the iOS emulator: https://github.com/facebook/react-native/issues/31179#issuecomment-830184757
