FlutterアプリをiOSの実機で動かすときに途中で落ちる

Launching lib/main_development.dart on ○○のiPhone in debug mode...

main_development.dart:1

Automatically signing iOS for device deployment using specified development team in Xcode project: aaaaaaaaaa

Xcode build done. 72.8s

(lldb) warning: libobjc.A.dylib is being read from process memory. This indicates that LLDB could not find the on-disk shared cache for this device. This will likely reduce debugging performance.

iOS Observatory not discovered after 30 seconds. This is taking much longer than expected...

process interrupt

error: Failed to halt process: Halt timed out. State = running

Error launching application on ○○のiPhone.

上記のようなエラーが出てくる場合はキャッシュが悪さをしている。対応策としては下記。

iPhoneの再起動

Flutterのクリーンと再ビルド

flutter clean

flutter pub get

flutter run

Xcodeプロジェクトのクリーン

Xcodeのバージョンアップ

iOSのバージョンアップ後など、これでハマりがち。

Cocoapodsのアップデート

sudo gem install cocoapods
