Hello. The underlying SDK does not officially supports beta version currently. It will be solve before release.

@Lyokone cmon, it's one line fix. Just change ios/Classes/FLTFirebaseMessagingPlugin.h:12:9 to @import FirebaseMessaging;

Does this mean it is impossible to run any apple betas while developing apps with flutter and firebase?

Actually i discovered no issues with firebase itself, the only problem is something changed in Xcode 16, perhaps "Allow Non-modular Includes in Framework Modules" setting doesn't work anymore. So it should be fixed in this library not in underlying library nor somewhere else

[Wahidsmn]

I found a solution until this is fixed. hopefully this helps someone. @AlexStrNik is right, xcode setting changed in the latest beta version of xcode, maybe apple is moving away from supporting the include of non-modular header inside framework modules.

steps to solve

1. select the runner
2. go to build settings
3. scroll down to Apple Clang - Language - Modules
4. change the Allow Non-modular includes in Framework Modules to "Yes" (by default this is set to "No" now)

I'm facing the same issue and also can't locate the 'Allow Non-modular Includes in Framework Modules' in Xcode 16 beta 3. This option is available in Xcode 15, set to 'No', and the project runs without issues there. I'm currently using Flutter (Channel stable, 3.22.2).

Any suggestion?

Same for me. On Xcode 16 beta 3, I can't find the 'Allow Non-modular Includes in Framework Modules' option. I recently sent a message to Xcode assistance, so I might have a solution from Apple soon. I will let you know as soon as I have any updates.
