I have an issue with Flutter. I can't run my app on an iOS simulator. I've tried to create a new certificate under the Mac keychain and that didn't help me much. Does anyone know how I can fix this problem?

The answer is in your flutter doctor:
✗ Flutter plugin not installed; this adds Flutter specific functionality.
✗ Dart plugin not installed; this adds Dart specific functionality.
You will need to fix these issues by setting it all up again as shown here: https://flutter.io/setup-macos/

I'm new to iOS development and I ran into this problem at the very beginning:
When I tried to flutter run my hello world app I got xcodebuild failed (I took only the last lines since it's too long):
81 errors generated.
<unknown>:0: error: failed to emit precompiled header '/Users/mehec/Library/Developer/Xcode/DerivedData/Runner-cssmbpuzzkyjvpfghedbpvdhbbmr/Build/Intermediates.noindex/PrecompiledHeaders/Runner-Bridging-Header-swift_2PXLF604USZTM-clang_KLU4EDN5EN1U.pch' for bridging header '/Users/mehec/Desktop/bgp/learn_flutter_0_test/ios/Runner/Runner-Bridging-Header.h'
<unknown>:0: error: generate-pch command failed with exit code 1 (use -v to see invocation)

note: Planning build
note: Constructing build description
I then tried to build and run in xcode and everything's fine.
I have tried flutter clean and flutter upgrade even creating a new project but no effect
I'm using macOS 10.14.6, IntelliJ Idea 2020.1, Flutter 1.17.5 and 1.19.0, Xcode 11.3.1
the code in main.dart:
import 'package:flutter/material.dart';
void main() {
runApp(Center(
child: Text(
"hello world",
textDirection: TextDirection.rtl,
),
));
}

Thanks!
I had a similar problem.
The build from Xcode.app was successful, but the build from the command line or Android Studio failed.
Finally, I reinstalled rbenv, and the problem went away.
In other Github comments, some people solved the problem with conda deactivate, so I think the problem is caused by a bug in the development environment that Xcode.app does not refer to, such as ruby or python environment.
Flutter failed to start-up on real IOS device (not emulator), its working fine on the IOS emulator but when I connect my device its installed but fails to launch without printing any message on flutter application log.

could you please help!
There was an issue on Flutter repository as mentioned by #amer rawashdeh.
iOS 13.4 is now available, please update your iOS device and Xcode to v11.4 to keep your project newly working.
If you are on Flutter stable channel you need also to apply this guide to keep you project working with v11.4 Xcode
It seems the problem with ISO version 13.3.1 only
check it out:
https://github.com/flutter/flutter/issues/49504#issuecomment-581554697
The application was working on IOS emulator version 13.3
I recently upgraded Flutter framework, and when I try to build and run the project from Android Studio, I get the following warnings and error:

Could not build the application for the simulator.

If I open the project in Xcode, I get the same warnings, but somehow I manage to build and run successfully on the Simulator.
I tried some suggestions from GitHub Issues regarding paths & symlinks, but they seem to not work.
Also added flutter doctor info:

I'm trying to build an archive by doing flutter build ios but I encounter a problem on Starting Xcode build
$ flutter build ios

I already build an archive one (last week) and it was working. Maybe this is due to flutter upgrade ?
$ flutter doctor

That's an issue that was fixed very recently and the fix should already be available in the master channel.
flutter channel master
flutter doctor
You can also try dev channel, but I'm not sure if it landed there already.
The fix will of course be included in the next beta channel, but a beta release just came out last week, so it will probably take a while to the next.

No matter which dart package I am trying to fetch, pub fails retrieving it.
When in my project root folder, I run:
flutter packages get
I consistently get:
Got socket error trying to find package cupertino_icons at https://pub.dartlang.org.
pub get failed (69) -- attempting retry 1 in 1 second...
Here is the output from flutter doctor:

and the pubspec is what comes with IntelliJ Flutter's wizard:

description: A new Flutter project.
dependencies:
flutter:

# The following adds the Cupertino Icons font to your application.
# Use with the CupertinoIcons class for iOS style icons.
cupertino_icons: "0.1.1"
Any idea how to fix pub?
So... restarting my laptop just fixed it. 😕
