IPHONEOS_DEPLOYMENT_TARGET is set to 8.0 Xcode 12 (Flutter)

Question

I run my Flutter project in Android Studio, pod installation goes well but Xcode build fails at the end every time like 20/30 steps first of complete the whole build. The weird fact is that Android Studio says :

Command PhaseScriptExecution failed with a nonzero exit code

But when I open the workspace with Xcode I see that my target in Runner has iOS deployment target 14.0 so I don't understand, it should be set to 14 but actually it's 8. Flutter generated Podfile, Podfile.lock and Pods through flutter run I prefer to let Flutter handle Pod generation and installation without using pod init, pod install or editing Podfile.

Solution 1

In addition to what Akif said, here's a running list of reasons why this error could be showing up for you:

1. Set the MinimumOSversion to 9.0 in ios/Flutter/AppFrameworkInfo.plist
2. In Xcode, ensure that the iOS deployment target at Runner -> Project -> Runner is set to 9.0
3. In Xcode, ensure that the Deployment Info in Runner -> Targets -> Runner is set to iOS 9.0
4. Double check that your GoogleService-Info.plist is there and was added via Xcode (not copy/pasted into the directory via Finder for example)
5. Uncomment the #platform :iOS, '9.0' line in your ios/Podfile

Then, run the following in your terminal to build with a fresh state:

flutter clean \
        && rm ios/Podfile.lock pubspec.lock \
        && rm -rf ios/Pods ios/Runner.xcworkspace \
        && flutter build ios

Solution 2

replace this code of pod file:

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

Solution 3

You need to set MinimumOSVersion to 9.0 in ios/Flutter/AppFrameworkInfo.plist. It will look like this:

  <key>MinimumOSVersion</key>
  <string>9.0</string>

Solution 4

Error is self-explanatory that deployment target is missed for application.

This will be added in two places inside Xcode, check the below screenshot where iOS Deployment Target is mention.

1. Runner

2.Pod

Solution 5

If after trying all the solutions above, your code is still not working, especially after an update/upgrade...

Just check out your dart version and also check out for null safety packages...

I just solved mine after battling with errors for days by properly migrating my codes to null safety.

I don't have this folder. My path is "ios/Flutter/" and inside Flutter I have "App.framework, flutter_export_enviroment.sh, Flutter.framework, Flutter.podspec, Generated.xconfig".But inside Flutter.framework there's a "Info.plist". And here yes there's the voice "MinimumiOSVersion" and I set it to 14, is it correct?

[Akif]

No, set it to 9.

[Finley Adams]

There isn't "Deployment info" but "Deployment target" instead, and both are set to 14, is it the same?

[Finley Adams]

Ok I trust you but why? Isn't better to set it for newer versions?

[Akif]

No. You are defining the minimum OS version. And It should be at least 9.0 for iOS. And the newer versions like 10, 11, 12, 13, 14 can use your app. But if you set it to 14, then only iOS14 iPhones will use your app.

[Finley Adams]

Oh you're right thanks! Ok I did it but when the run ends that line has been changed back to 8.0 and I have the same error.

[Finley Adams]

I did all these stuffs but when the run ends I have "MinimumiOSVersion" back to 8.0...And the same error again

[Akif]

Follow the steps of @thefoxrocks's answer.

[Finley Adams]

I did it but I have the same error, maybe Xcode version 12 isn't a good choice?

[Finley Adams]

Let us continue this discussion in chat.

[Akif]

I'm in the chat room.

[Akif]

remove # and uncomment that line in the podfile. # platform :ios, '9.0'

[Finley Adams]

Did it but still the same, nothing changed

[Akif]

I'm in the chat room again.

[Akif]

you can try to add that line in ios/Runner/info.plist: <key>MinimumOSVersion</key> <string>9.0</string>

[thefoxrocks]

@FinleyAdams Make sure you're setting the right AppFrameworkInfo.plist that's in ios/Flutter. I know there's another AppFrameworkInfo that will override at build time which might be the one you're using.

[genericUser]

"flutter build iOS" should be lowercase "flutter build ios"

[waletoye]

@Akif can you help out. having same exact issues. flutter

[Akif]

Define the issue in a new question!

[PAYRE Quentin]

Infortunetly I got this : The Xcode project defines schemes: dev, prod, staging You must specify a --flavor option to select one of the available schemes.. I pass the entire day figuring out how to solve this issue.. migrate from 2.0.3 to 2.0.5

[Kishan Dhankecha]

@FinleyAdams Have you got the solution??

[Alexa289]

what do you mean with check out dart version? and how to solve the issue? could you please elaborate more?

[LearningPath]

This is non quality to have to specify ios platform in various location...there should be a single entry point...I feel ios coding environment is quite a bugging mess with a lovely interface

[goldensoju]

for flutter apps, flutter_additional_ios_build_settings(target) should be added after line installer.pods_project.targets.each do |target|.
