I have flutter project, I'm trying to run the iOS version but I get error after I update flutter and Xcode to the latest version, I use firebase core plugin
error:
Could not build the precompiled application for the device.
Error (Xcode): File not found: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/lib/arc/libarclite_iphoneos.a
Error (Xcode): Linker command failed with exit code 1 (use -v to see invocation)
Podfile:
# Uncomment this line to define a global platform for your project

ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,

}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
end
post_install do |installer|
installer.pods_project.targets.each do |target|
flutter_additional_ios_build_settings(target)
end
end
I also tried to all installed pods by:
pod deintegrate
rm Podfile.lock
rm -rf Pods
and then update the repositories and install the pods and I still get the same error, should I reninstall xcode?
Flutter packages:
firebase_core: ^2.8.0
firebase_crashlytics: ^3.0.17
firebase_analytics: ^10.1.6
firebase_messaging: ^14.3.0
Any workaround for this? and thank you for your time
New answer (Edit 4)
if you upgrade your Flutter and cocoa pods and Flutter plugins and still have this issue, A really simple and efficient solution is to edit your Podfile
platform :ios, '14.0'
# CocoaPods analytics sends network stats synchronously affecting flutter build latency.
ENV['COCOAPODS_DISABLE_STATS'] = 'true'
project 'Runner', {
'Debug' => :debug,
'Profile' => :release,
'Release' => :release,
}
def flutter_root
generated_xcode_build_settings_path = File.expand_path(File.join('..', 'Flutter', 'Generated.xcconfig'), __FILE__)
unless File.exist?(generated_xcode_build_settings_path)
raise "#{generated_xcode_build_settings_path} must exist. If you're running pod install manually, make sure flutter pub get is executed first"
end
File.foreach(generated_xcode_build_settings_path) do |line|
matches = line.match(/FLUTTER_ROOT\=(.*)/)
return matches[1].strip if matches
end
raise "FLUTTER_ROOT not found in #{generated_xcode_build_settings_path}. Try deleting Generated.xcconfig, then run flutter pub get"
end
require File.expand_path(File.join('packages', 'flutter_tools', 'bin', 'podhelper'), flutter_root)
flutter_ios_podfile_setup
target 'Runner' do
use_frameworks!
use_modular_headers!
flutter_install_all_ios_pods File.dirname(File.realpath(__FILE__))
target 'RunnerTests' do
inherit! :search_paths
end
end
#post_install do |installer|
# installer.pods_project.targets.each do |target|
# flutter_additional_ios_build_settings(target)
# end
#end
post_install do |installer|
installer.pods_project.targets.each do |target|
target.build_configurations.each do |config|
if Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET']) < Gem::Version.new('13.0')
config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '13.0'
end
end
flutter_additional_ios_build_settings(target)
end
end
The changes that I made, is to define the platform ios version as a minimum of 14, and make sure all the pods have at least 13 minimum version, otherwise ignore it, the changes are to the second line and the post_install at the very end
Old answer (Edit 1, 2 and 3)
I fixed the issue, even though I'm not sure if that is a good solution, run the following:
flutter clean
flutter pub get
cd ios/
pod deintegrate
pod install
pod repo update
pod install (again)
Just open the ios project inside the flutter project in Xcode, go to Pods in the folders (files) tab, go to the targets, go to the targets (it pod I guess, one dependency) that causes the issue, in my case FMDB and App auth, upgrade the minimum deployments for both from the current version (in my case 9.0) to 13.0 and try run the app again by build it and run it in Xcode or using flutter run with the selected ios device, and the issue should be gone
however sometimes when you clean the project in flutter (using flutter clean), it will reset those changes, or when you delete the pods and deintegrate Cocapods and re-install the app, all the changes will be reverted back to the default, it not really an efficient solution, but at least you can run the app
and if the issue is still exists, update the minimum deployment for the pods target again and run the app using Xcode, if you still have the issue, try out the other answers or you can try update cocapods by
sudo gem install cocoapods
if your mac machine is apple silicon (m1, m2), you also need run
sudo gem uninstall ffi && sudo gem install ffi -- --enable-libffi-alloc
The official documentation said that
Edit: This solution idea come to me, all thanks to @Siyu
If you are from the future, you might want to try to upgrade the packages and cocapods, flutter etc...
Edit 2:
Try updating Flutter since the issue should be fixed in 3.7.11
flutter upgrade
Edit 3:
The issue comes back again in the flutter 3.10 with some packages, so please use the way I used or try one of the answers and try to understand it, thank you for your time, Good luck
