Error running pod install Error launching application on iPhone X.

Solution 1:

My setup: VS Code, Flutter

If you don't have Podfile.lock file and pod update doesn't help, try this:

1. Go to ios/Pods/Local Podspecs directory in your project
2. Check every json file to find highest required ios version. Mine was "ios": "10.0" in some of them
3. Go back to ios/ directory
4. Open Podfile file
5. Uncomment # platform :ios, '9.0' and replace 9.0 with version from 2. step, for example 10.0.
   • # platform :ios, '9.0' > platform :ios, '10.0'
6. Run pod install and the error should be gone

Solution 2:

pod update

Should do the trick. You're welcome :-)

Solution 3:

This issue can happen when you upgrade your FlutterFire packages and attempt to build for iOS or macOS, this is usually down to one of the following:

Here is some reason and their solution

1. BREAKING FEAT: forward port to firebase-ios-sdk v7.3.0.

• Due to this SDK upgrade, iOS 10 is now the minimum supported version by FlutterFire. Please update your build target version.

  Solution:

  Go to the file ios/Podfile inside your project, and uncomment


  # platform :ios, '9.0'
  

  Then change the version to 10


  platform :ios, '10.0'
  

  And Go back to ios/ directory and Run pod install in your terminal and try your build again.

2. Your Podfile.lock version inside your iOS or macOS directory is out of date and locked to older versions of the Firebase iOS SDKs whereas the newly upgraded FlutterFire packages might be using newer versions of these SDKs.

   Solution: Delete the Podfile.lock file and try your build again. This file will get regenerated after the next pod install.

3. Your pod specs repo is out of date, meaning CocoaPods locally isn't aware of any potential newer versions of the Firebase iOS SDKs that have been recently published.

   Solution: Go back to ios/ directory and Run pod repo update in your terminal and try your build again.
