I have a flutter app that runs on android and uses several plugins which work perfectly and all of them have support for iOS. I am trying to run it on a Mac using VSCode and its throwing a bunch of errors saying it can't find packages that are there. I am trying to start with one, fix it and then move to the next but after adding the proper Key / Value pairs for the Device_Calendar plugin in info.plist but it is not fixing it.
ERROR
lib/calendar/calendars.dart:1:8: Error: Error when reading '../../Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/device_calendar-3.0.0+1/lib/device_calendar.dart': No such file or directory
import 'package:device_calendar/device_calendar.dart';
Here is the plugin:
import 'package:device_calendar/device_calendar.dart';
I added this to info.plist :
<key>NSCalendarsUsageDescription</key>
<string>INSERT_REASON_HERE</string>
plugin - device_calendar 3.0.0+3

I'm currently stuck on a problem related to my Ionic project.
I have an Ionic project on GitHub which i've been working on in the past few weeks, i have a few Cordova plugins as part of the project.
When downloading the project from GitHub, i can run the app using Ionic Serve without a problem. However, when trying to setup the project for xCode to run on local device(s), i run into a multitude of errors
Some include:
When running ionic 'cordova platform add ios' the following error appears
Error: Could not install from "ios" as it does not contain a package.json file.
When trying to run 'ionic cordova run ios -l --external'
Error: Error: terminating with uncaught exception of type NSException
I have not yet tried to transfer my code into a new Ionic project, as i wish to see if my problem can be solved without that hassle.

I figured it out. You have the exact same issue I've had with the android platform.
As I pointed it out in the comments, it is indeed caused by a "corrupted" project architecture.
How it happened
Initially, I had an issue with the cordova generated resources, somehow not being copied into the android platform directory. I tried plenty of things with the cordova-res CLI, including using the --copy and the --ios-project flags to force the copy to happen in the directory of my choice.
I couldn't manage to fix my issue, and then decided to rollback all my changes and start over on a clean project to try something else. Since then, I was not able to add the android platform anymore. Every single time, the following error was being thrown :
Error: Could not install from "android" as it does not contain a package.json file.
Explanation
With all my testing, I noticed that when using cordova to add the platform or copy the resources over, somehow, it had created the android platform in the wrong directory, at the root of my project instead of in the platforms folder. And that's where the issue comes from.
I can't explain it, but you will encounter this error every single time if you try to add a platform with cordova while having a folder with this platform name at the root of your project. I have no idea why this would prevent a platform from being added to the project, maybe this folder is used as a temp folder by the CLI.
Solution
The fix is to simply remove any ios or android directory at the root of your project.
The error will go away and you will be able to add the platform again.
#CodingJunkie
Regarding the Github repository you provided in your post, you will likely run into another error while trying to add the ios platform if you use cordova#>=9.0.0.
Using "requireCordovaModule" to load non-cordova module "xcode" is not supported.
Instead, add this module to your dependencies and use regular "require" to load it.
Check this issue#1033 for a workaround. However, it's not recommended to directly edit the plugin source code, you might want to look for another cordova Firebase plugin.
I also noticed you kinda mixed up cordova and capacitor in your project.
Make sure to use one or the other to avoid potential errors.
Hope this helped !
#Reqven
Thank you for your support! - i was sure that i had done this step while trying to fix the issue. It is such an absurd problem, it seems that there is a new project architecture as you mentioned which needs to be followed. I followed your steps with also one minor additional step as im working on the iIOS platform:
Delete iOS folder
cordova platform add ios
cordova prepare ios
ionic build
If step 2 throws an error causing the version not to be found or integrated into the project run - include '#latest' this also solved my problem
I'm trying to build and run an iOS simulator version of the getting started React Native project from the instructions at:
https://facebook.github.io/react-native/docs/getting-started.html
The app launches in the XCode simulator, displays it's window very briefly but then an exception occurs that opens a red screen with the message
"Requiring unknown module "498".If you are sure the module is there,
try restarting Metro Bundler. You may also want to run yarn, or npm
install (depending on your environment).
loadModuleImplementation require.js:176:29
viewPropTypes.js:15:30
loadModuleImplementation require.js:212:12
View.js:20:22
loadModuleImplementation require.js:212:12
AppContainer.js:22:13"
etc
Line 15 of ViewPropTypes is
const PlatformViewPropTypes = require('PlatformViewPropTypes');
Line 20 of node_modules/react_native/Libraries/Components/Views/View.js is
const ViewPropTypes = require('ViewPropTypes');
Note: There is another, 15 line View.js files in the directory structure at node_modules/react_native/lib/ it's basically a stub containing
// This is a forwarding module to allow React to require React Native internals
// as node dependency
module.exports = require('View');
I'm on the latest of everything, MacOS High Sierra (10.13.4), XCode 9.3 with 9.3 command line tools installed. I've tried running yarn and npm install, and a fresh install. Obviously I have NPM and Watchman installed. Any ideas why the stock example won't run for me?
Newbie mistake. I had previously attempted to build a different React Native project in a different directory, and Metro Bundler was still pointed at the previous project. As the error message suggested, restarting Metro Bundler fixed the problem.
Also didn't realize the errors in the exception screen were tappable, they take you right into the Metro Bundler terminal process for more detail. Hope this helps someone else too!
In my case, just close all the related process, and re-run react-native run-android solved the problem.
refer to: https://github.com/facebook/react-native/issues/11568
I had the same issue.
In my case, while creating a reusable component, I wasn't importing React into the file,as I was not using them(in functional component) in the component file.
Turns out that jsx to React Element conversion happens per file/module basis, so we should import React and component in every file.
Including Both React and Component normally, solved the problem.
For me I got "955" error. And a simple solution was to
import React, {Component} from "react";
This is a long shot, but I've taken over a project done in RN v .38 and I need to update a library and resolve the build issues without updating the version of react native. I'm trying to update the react-native-aws-cognito-js library and while it looks to be compatible with the formatting change of import statements, I'm still not able to get it to build on IOS. Android is fine.
To reproduce my issue I did the following:
react-native init sample --version 0.38.0
cd sample
npm install react-native-aws-cognito-js
react-native link react-native-aws-cognito-js
react-native run-ios
Which fails with:
/node_modules/react-native-aws-cognito-js/ios/RNAWSCognito.h:4:9:
fatal error: 'React/RCTBridgeModule.h' file not found #import
Mobile and RN development is not my wheelhouse, but I'm hoping there is some sort of xcode configuration or tricks I can do to get this working and avoid a major overhaul. Running an upgrade to >.40 would probably take too long and also cause other compatibility issues that I don't have the time to resolve.
Note: I have tried the suggestions in `React/RCTBridgeModule.h` file not found
I am new to development, I have followed instructions, downloaded a zip of the dev's project,unzip,cd to folder, ran npm install and npm start
In the example app folders when trying to build in Xcode I get numberous React/RCT{file} file not found and will highlight an invalid import statement such as #import
I have been chasing this issue around github for days, tried numerous fixes such as updating the schemes, making an extra cocopods file that references the libraries functions
Anyone have a solution to this referencing problem?
these kinds of errors

Frankly I mightnt even be installing the project folder correctly, I dont know
thanks
I have a strange problem. I develop an app using Ionic on a samba network drive.
I develop on a windows machine and run all the command lines regarding Android development. I switch to a Mac to be able to build for iOS.
All went fine and as expected the last couple of days. Today I edited some HTML, JS and CSS files - just some minor improvements. I built the app for android on the windows machine (plus using jarsigner and zipalign - only if that should matter).
On the Mac I had troubles. Suddenly I get errors when trying to run ionic build --release ios (as I already did successfully the last couple days).
The executed script creates files and folders starting with "._" which were never created before and are already existing without it. This results at some point in an ENOENT (no such file or directory) aborting everything.
I don't get it. I already de-/re-installed node, npm, cordova and ionic. But nothing helped.
I would love to support you guys with additional error messages or logs, but due to I'm fairly new to mobile development (and using a Mac), I don't know what information would be helpful and what not.
Sp please tell me any information you need and I'll be happy to supply them.
I accidentally solved my own problem. I just "removed" the platforms directory (by renaming it) and re-added the platform using the command cordova platform add ios.
After that I could build my app as it did before. Don't know why or what actually triggered this behavior, but at least I'm able to proceed.
If somebody knows how to prevent that from happening again (so that I don't loose all the project settings I configured in Xcode), I would appreciate it.
This happened to me, too - I found this bug in the Cordova issues:
https://issues.apache.org/jira/browse/CB-5644
I found out that Xcode created the file PROJECT_PATH/platforms/ios/._APPNAME.xcodeproject. I deleted this file and "cordova prepared ios" was working again.
...
It should ignore files starting with ._ as they are hidden system
files used by osx to store infos about a file
