The iOS Simulator deployment targets is set to 7.0, but the range of supported deployment target version for this platform is 8.0 to 12.1

Question

I'm getting this below warning message in my Xcode 10.1.

The iOS Simulator deployment targets are set to 7.0, but the range of supported deployment target versions for this platform is 8.0 to 12.1.

My simulator os in 12.1 Xcode 10.1

And I updated my pod file.

My deployment target is 9.0

In my target

Answer 1

You can setup your podfile to automatically match the deployment target of all the podfiles to your current project deployment target like this :

post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '9.0'
  end
 end
end

Answer 2

The problem is in your pod files deployment target iOS Version not in your project deployment target iOS Version, so you need to change the deployment iOS version for your pods as well to anything higher than 8.0 to do so open your project workspace and do this:

1- Click on pods.

2- Select each project and target and click on build settings.

3- Under Deployment section change the iOS Deployment Target version to anything more than 8.0 (better to try the same project version).

4- Repeat this for every other project in your pods then run the app.

Answer 3

Instead of specifying a deployment target in pod post install, you can delete the pod deployment target, which causes the deployment target to be inherited from the podfile platform.

You may need to run pod install for the effect to take place.

platform :ios, '12.0'

  post_install do |installer|
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
  end

Answer 4

Iterating over the answer from Tao-Nhan Nguyen, accounting the original value set for every pod, adjusting it only if it's not greater than 8.0... Add the following to the Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      if Gem::Version.new('8.0') > Gem::Version.new(config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'])
        config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '8.0'
      end
    end
  end
end

If anyone came here from react native issue, just delete the /build folder and type react-native run ios

Answer 6

I solved this problem, I changed build system to Legacy Build System from New Build System

In Xcode v10+, select File > Project Settings

In previous Xcode, select File > Workspace Settings

Change Build System to Legacy Build System from New Build System --> Click Done.

Answer 7

Try these steps:

1. Delete your Podfile.lock
2. Delete your Podfile
3. Build Project
4. Add initialization code from firebase
5. cd /ios
6. pod install
7. run Project

This was what worked for me.

Answer 8

We can apply the project deployment target to all pods target. Resolved by adding this code block below to end of your Podfile:

post_install do |installer|
  fix_deployment_target(installer)
end

def fix_deployment_target(installer)
  return if !installer
  project = installer.pods_project
  project_deployment_target = project.build_configurations.first.build_settings['IPHONEOS_DEPLOYMENT_TARGET']

  puts "Make sure all pods deployment target is #{project_deployment_target.green}"
  project.targets.each do |target|
    puts "  #{target.name}".blue
    target.build_configurations.each do |config|
      old_target = config.build_settings['IPHONEOS_DEPLOYMENT_TARGET']
      new_target = project_deployment_target
      next if old_target == new_target
      puts "    #{config.name}: #{old_target.yellow} -> #{new_target.green}"
      config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = new_target
    end
  end
end

If your are come from react-native and facing this error just do this

1. Open Podfile(your project > ios>Podfile)
2. comment flipper functions in podfile as below

#use_flipper!
 #post_install do |installer|
   #flipper_post_install(installer)
 #end

3. In terminal inside IOS folder enter this command pod install

yep, that is it hope it works to you

Answer 10

if anybody is experiencing is issue while updating to the latest react native, try updating your pod file with

  use_flipper!
  post_install do |installer|
    flipper_post_install(installer)
    installer.pods_project.targets.each do |target|
      target.build_configurations.each do |config|
        config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
      end
    end
   end

Answer 11

For Swift

If you are using CocoaPods with Xcode 12, then you have probably seen this error:

The iOS Simulator deployment target 'IPHONEOS_DEPLOYMENT_TARGET' is set to 8.0, but the range of supported deployment target versions is 9.0 to 14.

This is happening because support for iOS 8 has been dropped, but the minimum deployment target for the pod is iOS 8.

Until this is fixed, you can add the following to your Podfile:

post_install do |installer|
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

This will remove the deployment target from all the pods in your project and allows them to inherit the project/workspace deployment target that has been specified at the top of Podfile.

For React Native

Delete the ./project-root/ios/build folder and type react-native run ios

For Cordova

<preference name="deployment-target" value="8.0" />

Answer 12

Simple fix that worked for me in Flutter:

1. Delete Podfile and Podfile.lock
2. Run app: This will create a new Podfile. This will probably still fail with an error.
3. In the new Podfile, uncomment and change the 2nd line to platform :ios, '12.0' (or other min version you want to target)
4. Run app again, now without errors

Answer 13

for cordova developers having this issue

try to set

<preference name="deployment-target" value="8.0" />

in confix.xml

Answer 14

This solution worked for me for Flutter. open {your_project_root_folder}/ios/Podfile and replace the post_install block with 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.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end

Answer 15

first change the deployment to your choose : like '11.0' and add this step in the last of your pod file

end
post_install do |installer|
 installer.pods_project.targets.each do |target|
  target.build_configurations.each do |config|
   config.build_settings['IPHONEOS_DEPLOYMENT_TARGET'] = '11.0'
  end
 end
end

Answer 16

platform :ios, '10.0'

post_install do |installer|
  installer.pods_project.targets.each do |target|
    flutter_additional_ios_build_settings(target)
  end
  installer.pods_project.targets.each do |target|
    target.build_configurations.each do |config|
      config.build_settings.delete 'IPHONEOS_DEPLOYMENT_TARGET'
    end
  end
end
