Can I use the version of Objective-C? about flutter_crashlytics HOT 14 CLOSED

@bjon
I just encountered this problem last week, I spent 2 days to solve it, I am a new iOS, this problem appears in the Object-C and Swift plug-in hybrid project, just need to create a new in the Runner directory of the Xcode project Just a Swift file.

If I add use_frameworks!, there will be other errors. And I saw that it could not be solved. I am not very familiar with iOS, if you can come to an Objective-C version, thank you very much.

Hello @yy1300326388

Did you add use_frameworks! on your pod file of your app ? If you're under a framework, you can't use this plugin because of limitation on cocoa pods that doesn't get the transitive dependancies on nested frameworks.

I'll not have the time to transpose the plugin in ObjC, but PR are welcome if you're sure it will fix your problem.

I have the same problem with use_frameworks! (build error on ios). Its sad cause its working great on android.

I'm using this plugin with firebase_analytics google_sign_in and just try to add google_maps_flutter on my pub spec and I'm still able to build and launch the app... That's strange

Even with a new project with flutter_crashlytics as the only depencency, build still fails.
See build-output.

When switching to geolocator (also a swift plugin) the build succeeds.

because you miss use_frameworks! on PodFile, the use_frameworks! is mandatory for this library to works because of bundle static libraries.

from flutter_crashlytics.

Or create a project with Swift support from the start. Adding a swift file on existing project enable the swift support that's why it's working. But use_framework! still need to be added :)
I'm closing this issue as it works as expected on project with Swift enabled. If an objective C version is really needed PR are welcome :)

Its in the Podfile

target 'Runner' do
  use_frameworks!

Do you mean it has to be in the top of the file?

I put it at the top of the file personally
