A function declaration without a prototype is deprecated in all versions of C in Xcode

mac os sonoma: 14.5

Ionic Framework : @ionic/angular 8.2.5
@angular-devkit/build-angular : 18.1.0

Get this message after installing @capactior-community.

Suppose it should be easy to fix it by adding void in into the function call but after fixing all, there will be another issues cannot fix by Xcode automatically .......

Reproduce the installation and Xcode build on macOS Sonoma using the listed Ionic, Capacitor, Angular, and Firebase versions. Start by identifying which @capacitor-community dependency emits the C compiler diagnostics; done means the iOS project builds without the prototype-deprecation warning or the subsequent reported errors.
