How do I fix this Flutter iOS build error?

Question

I'm making a simple text-to-speech app with the flutter TTS plugin, and running it on my physical iPhone and iPad for debugging.

I tried googling it, and the github repository for flutter said that I should run flutter analyze and I did that, but it says no issues found. So I'm not sure what to do. I think it's a problem with xcode.

Here is my error:

Failed to build iOS app

Answer 1

- Platform in ios/podfile you can use platform :ios, '10.0'
- If you are changing platform version in podfile than you have to also change version in AppFrameworkInfo.plist.
- Also change version in Deployment Target and Deployment Info of Runner.

- If not working than you have to try with this below commands using for uninstall and install again pods and Run.

flutter clean
rm -Rf ios/Pods
rm -Rf ios/.symlinks
rm -Rf ios/Flutter/Flutter.framework
rm -Rf ios/Flutter/Flutter.podspec
rm ios/Podfile
flutter run

Answer 2

Follow the below steps:

1. Go to ios/Podfile and uncomment platform: ios parameter and replace with

   platform :ios, '9.0'

2. Run the below command inside the ios folder structure

   pod install

3. Run command flutter upgrade

4. Run command flutter run

Answer 3

you need to change the deployment target to 9 or in my opinion 10 by changing it in the xcode runner and target , also you need to change it in the pod file , uncommenting this #platform :ios, '8.0' by deleting the # and change the string to 10.0. also you need to change this post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) into this post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) target.build_configurations.each do |config| config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '10.0' end end end at the the end of your pod file

Answer 4

Change the version to 9.0 here and it would work fine.
