如何在codemagic中创建podfile？

Question

I'm trying to build an iOS flutter app in windows using Codemagic. I created the flutter project in android studio and uploaded it to github in order to use it in Codemagic... But when I try to build the iOS app, Codemagic throws me this error:

Warning: Building for device with codesigning disabled. You will have to manually codesign before deploying to device.

Building a deployable iOS app requires a selected Development Team with a 
Provisioning Profile. Please ensure that a Development Team is selected by:
  1- Open the Flutter project's Xcode target with
       open ios/Runner.xcworkspace
  2- Select the 'Runner' project in the navigator then the 'Runner' target
     in the project settings
  3- Make sure a 'Development Team' is selected. 
     - For Xcode 10, look under General > Signing > Team.
     - For Xcode 11 and newer, look under Signing & Capabilities > Team.
     You may need to:
         - Log in with your Apple ID in Xcode first
         - Ensure you have a valid unique Bundle ID
         - Register your device with your Apple Developer Account
         - Let Xcode automatically provision a profile for your app
  4- Build or run your project again

For more information, please visit:
  https://flutter.dev/setup/#deploy-to-ios-devices

Or run on an iOS simulator without code signing

In this question , they solved this same problem creating a podfile. But how I create a Podfile? I have to create it in my project and then push it to github? Or there is a way to create it in Codemagic?

Answer 1

I think it might be enough to open up your project up in VSCODE and change the 'IPHONEOS_DEPLOYMENT_TARGET' to 9.0 in all 3 places where it is present. In addition check your AppFrameworkInfo.plist file and set the MinimumiOSVersion to 9.0 there as well.

If you wish to create a podfile through Codemagic however, then you might try to put this into your pre build script for the first run (and remove it later):

cd ios && pod init && git add . && git commit -m "Add Podfile to project" && git push

我，特别是，选择 beta 作为颤振通道并且运行良好，但还没有在真实设备上试用该应用程序。
