Hi everyone,

We had developed an iOS Application in Flutter and built it using XCode 26.0.1. We’re unable to install this application in iOS 18.7. Below are the details,

Development Environment:

  • Flutter: 3.32.2

Build Environment:

  • Xcode: 26.0.1
  • Build system: Flutter → flutter build ios --release, then opened in Xcode for signing

Device models tested:

  • iPhone (iOS 15.8.3 / 15.8.5) → :white_check_mark: installs and launches fine
  • iOS Simulator (iOS 18.6 / 26) → :white_check_mark: works fine
  • iPad (iOS 18.7) → :cross_mark: fails to install

Error message on iPad (iOS 18.7):

“Unable to install ‘’. Please try again later.”
