How can I regenerate ios folder in React Native project

Question

So a while ago I deleted the  ios directory in my react native app  let s call it X   I ve been developing and testing using the android emulator but now I d like to make sure it works on ios with xcode simulator etc    So my current idea is to create a new react native bare project  let s call it Y  with ios folder  then follow these steps to rename Y so that it has the name of X and then moving the  ios directory from Y into X and trying to run-ios    I ll update here how that goes  but I wondered if there is a better way and has nobody been in this situation before   I ve googled lots of things  regenerate ios folder   deleted ios folder   add ios folder to existing    and nothing helpful  Maybe my googlefu isn t good enough but if anyone has any suggestions  much appreciated   Step 2 will be making sure it compiles because of dependencies and stuff but for now my goal is to just get the  ios folder back in the project and for React Native to be aware of it s existence  it has all the necessary config    Thanks

If you are lost with errors like module not found there is noway other the than following method if you have used react native CLI I had faced similar issue as a result of openning xcode project from  xcodeproj file instead of  xcworkspace  Also please note that react-native eject only for Expo project  The only workaround to regenarate ios and android folders within a react native project is the following   Generate a project with same name using the command react-native init  Backup your old project ios and android directories into a backup location Then copy ios and android directories from newly created project into your old not working project Run pod install within the copied ios directory  Now your problem should be solved

I just found myself with this problem too  but I just solved it  Surely when running the  quot react-native upgrade quot  command  it gave them the message that it was not necessary to update or with the command  quot react-native eject quot  that the command is not recognized  react-native upgrade Now you should use the react-native upgrade --legacy true command to back up your android folders or ios as the case may be as this command will replace your files  react-native upgrade --legacy true Now it s just telling you not to replace your package json

The process you need to follow is so similar to renaming a react native app  Basically you just need to run react-native upgrade in your root project directory  For further info you can check another question here  The instructions below explains how to create another react native project based on a copied one with a new name    First copy the directory which your to-be-name-changed application exists  And go to your newly cloned directory  Change the name at index ios android js file which is given as a parameter to AppRegistry  Change the name and version accordingly on package json Delete  ios and  android folders which are remaining from your older app  Run  react-native upgrade to generate  ios and  android folders again  Run  react-native link for any native dependency  Finally run  react-native run-ios or anything you want

Since react-native eject is depreciated in 60 3 and I was getting diff errors trying to upgrade form 60 1 to 60 3 regenerating the android folder was not working   I had to   rm -R node modules   Then update react-native in package json to 59 1  remove package-lock json    Run   npm install  react-native eject   This will regenerate your android and ios folders Finally upgrade back to 60 3  react-native upgrade   react-native upgrade while back and 59 1 did not regenerate my android folder so the eject was necessary

Open Terminal cmd Move to the folder directory where the project  quot ProjectName quot  folder exist Do not go into project directory  run command as    react-native init  quot ProjectName quot  and it will warn that project directory already exist but you continue  It will install all updated node modules as well as missing platform  android ios  folders inside project without disturbing the code already written  cd  quot ProjectName quot  and then cd ios and then run pod install  PS  Take backup of your code in case it changes App js

It seems like react-native eject is no more available  The only way I could find for recreating the ios folder was to generate it from scratch   Take a backup of your ios folder   mv  path to your old project ios  path to your backup dir ios backup   Navigate to a temporary directory and create a new project with the same name as your current project  react-native init project name mv project name ios  path to your old project ios    Install the pod dependencies inside the ios folder within your project  cd  path to your old project ios pod install
