In Flutter project, I Also faced with this issue. Fixed by updating flutter and cocoa pods to the latest version.

Solution:

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
flutter pub get
cd ios
pod install # (or on an M1+ mac: arch -x86_64 pod install)
cd ..
flutter build ios
flutter run

On an M1 mac, arch -x86_64 pod install may have to be used instead of pod install – Belligerency 24/9, 2021 at 10:44

I had to run arch -x86_64 pod install --repo-update – Snappish 5/2, 2022 at 4:41

Had to do the following: cd ios, rm Podfile.lock and arch -x86_64 pod install --repo-update – Starlastarlene 21/3, 2023 at 12:53

I got this error when I was using Firebase in flutter, the solution for me was to set the Podfile deployment target to a iOS version higher than 9.

Example: Changed this

#platform :ios, '9.0'

to

 platform :ios, '13.0'

And as @Mana commented, remember the higher the version you set, your app will not be supported for users with lower IOS versions

Biota answered 18/6, 2021 at 17:51 Comment(3)

Updated to 14.5 and works. – Dullish 16/11, 2021 at 21:9

Same here, with Firebase in flutter. changed platform to 13.0 also works with iOS 15.3 – Whalebone 1/6, 2022 at 15:35

but pls remember the higher the version you set, your app will not be supported for users with lower IOS versions – Servile 24/6, 2022 at 10:14

I faced the same issue and none of the above work. Finally I resolved it by:

Check ios/.symlinks/plugins contains extra plugin which you are not using.
Delete podfile.lock in ios folder, if it exists.
Delete podfile from ios folder.
Delete pods folder in ios directory.
Run flutter clean in the terminal.
Run flutter pub get in the terminal.
Run flutter runin the terminal.

Worked with me after I updated my cocoapods (pod) from 1.10 to 1.11.2 – Surat 7/11, 2021 at 2:58

I followed your method and then ran brew reinstall cocoapods and it started working on M2 Pro 2022 – Offen 15/9, 2022 at 5:20

2022 update

After struggling for hours the following helped me:

sudo gem uninstall cocoapods
brew install cocoapods

Make sure you have HomeBrew installed before you do the above. Steps to install HomeBrew: Install HomeBrew

Phew!! That did it. Upgraded pod to 1.11.3. – Camisole 3/5, 2022 at 16:55

Type, flutter clean && pod update

No `Podfile' found in the project directory. – Iridaceous 29/2, 2020 at 16:12

Pod is located on project/ios folder, run cd ios – Lightness 7/11, 2020 at 15:32

if no podfile, clean and pub get – Nasion 31/12, 2020 at 9:24

1) flutter clean 2) flutter pub get 3) cd macos or cd ios 4) pod update Worked for me – Brocade 17/2, 2023 at 8:44

So did you solve this problem?

I met the same situation. And this is the solution I found. Link

Basically:

Locate Terminal.app in Finder. (Applications->Terminal.app)
Right-click and choose Get Info
Check the “Open using Rosetta”
Quit all instances of Terminal app and run it again
Run sudo gem install ffi

After you finish the above several steps, restart your IDE and re-run the application. Please give a reply if this method works.

Economizer answered 8/5, 2021 at 6:54 Comment(1)

Yes, "Run sudo gem install ffi" resolved the issue for M1 Mac. The terminal.app is located in (Applications->Utilities->Terminal). Right clicked Terminal, Get Info, and clicked the checkbox "Open using Rosetta". Then cd'd into flutter project, run flutter clean, flutter pub get, and flutter build iOS. This resulted in a "Building a deployable iOS app requires.." notice. Then app would run in iOS simulator. Thank you. – Fertility 1/11, 2021 at 12:24

I'm using VS Code and flutter 2.10.1 running intel mac

I've faced this problem several times, usually when switching between projects or when working with multiple versions of project. But the solution is pretty simple.

Inside your project parent directory go to, ios -> Podfile. Here the top line will be something like this,

# Uncomment this line to define a global platform for your project
# platform :ios, '9.0'

check whatever version you are using on simulator and replace '9.0' with that and uncomment.

# Uncomment this line to define a global platform for your project
platform :ios, '15.4'

Now if we try to run the flutter project, the debugger will say that the cocoapods are outdated. So just update them using command

pod repo update

And that should solve the problem.

There are multiple reasons this could occur so a one-size-fits-all solution won't exist.

Instead, in terminal, run:

$cd ios

$pod install

This will give you more in depth information on the error and you can search from there. In my case one of my dependencies required a higher minimum ios version so I had to open the .xcworkspace file and adjust the minimum deployment version in xcode>targets>general>minimum_deployments

This should have more upvotes as there are a lot of things that could cause this issue, and this one will help troubleshoot – Plumbism 29/3 at 18:38

Delete the podfile.lock (located in app root > ios folder)
Run in Terminal pod install --repo-update
flutter run

Did not work for me – Kristykristyn 16/11, 2023 at 13:39

Simply delete the Podfile from your project
Run this command in terminal (I did in Android studio terminal it self)

sudo gem install cocoapods

And then run this

pod init

It works for me..

The link https://cdn.cocoapods.org does not work correctly, I had to change the source in ios/Podfile as described in the code below:

Change source in ios/Podfile

# platform :ios, '9.0'

source 'https://github.com/CocoaPods/Specs.git'

Clean your project

flutter clean

Install referenced packages

flutter pub get

Run the app

The error can also come from a package which requires a version higher than '9.0' in this case it is necessary to uncomment the line # platform :ios, '9.0' and to pass for example to version '14.0' according to the version requested by the package.

For me none of the above helped, the following worked on my case:

Deleted the macos folder from main project.
Created a dummy flutter project.
Copied the newly created macos folder.
Pasted it to my main project.

Additionally I use firebase plugins, so I made some changes in pod file,.. It started running.

Open Your Terminal paste this line of code open ~/.zshrc press Enter

if you don't have the zshrc file you will have to create it, to create it you need to open terminal paste this code touch ~/.zshrc add you flutter path and move to Second instruction

2 The Text File will open add then you add this export LANG=en_US.UTF-8

I was trying to build flutter app in my M1 chip MacBook Air when I faced this issue, unfortunately the above solutions did not work for me but this did -

add to your ~/.zshrc or ~/.bashrc

export LC_ALL="en_US.UTF-8"

Reference - CocoaPods requires your terminal to be using UTF-8 encoding and it aborts to run pod

I'd the same problem, in my case when I ran pod install --verbose I realize that there was an specific error during pod install

undefined method `each_child' for #Dir:0x00007ff10befa7f0 Did you mean? each_slice

Looking for this specific error I found this answer and I realize that I was using ruby 2.5 and one file generated by Flutter for iOS devices was trying to use a method that was introduced on version 2.6.

After follow the steps on that answer I could run my Flutter app on iOS simulator.

The method dir.each_child was introduced in Ruby 2.6, but you are using Ruby 2.3.0.

You should update Ruby to 2.6.0 or later 2.x version.

After Ruby updating you may also need to restart your IDE and re-install cocoapods.

Check in ios/.symlinks/plugins for unused plugins. and if there are, remove from pubspec.yml. This solved my problem.

As per the install instructions make sure M1 users run. Solved the issue for me. I missed it on install!

$ sudo softwareupdate --install-rosetta --agree-to-license

I solve the same issue so:

Delete podfile.lock in iOS-folder app
Run pod repo update in the terminal
Re-compile my code

I had similar problems running flutter web on mac. Make sure you uncomment and update the podfile from macos folder not ios I'm talking about these lines:

# Uncomment this line to define a global platform for your project
platform :osx, '15.4'

If you want an automated script to change the deployment target, use

sed -i '' 's/9.0/10.0/' ./.ios/Podfile

where 9.0 is the generated iOS version and 10.0 the desired

on your pipeline, shell script or whatever

If anyone is struggling on M1 machines with a particular pod, the following helped me:

flutter precache --ios  
arch -x86_64 pod update Firebase/Firestore //or name of pod from the error

I got this error after install in_app_purchase: ^3.1.5 in flutter for macos

I solve : Make sure that in podfile and target platform in runner the version are the same and minimum 10.14 , but maybe you try next versions for other packages error

from flutter_project_folder -> macos -> Podfile , in this file edit and first line usually "platform :osx, '10.XX'" so change to "platform :osx, '10.14'" and in xcode open macos folder in the flutter project , then in runner -> select the macos target to match as in Podfile , here i change bothed to 10.14 the version

check as below image in xcode :

and for Podfile :

run this code on the terminal

sudo arch -x86_64 gem install ffi

Next, go to the ios folder in your project, and open Podfile.

Then change #platform :ios, '9.0' to platform :ios, '10.0'
