How does Sentry choose SDK?

I noticed that the same app version may use different sdks for error reporting.
I have read the source code, but I don't understand anyway why sdk is different. According to SentrySdk.cs, Cocoa SDK should always be used on iOS

Code from SentrySdk.cs:

// Initialize native platform SDKs here
        if (options.InitNativeSdks)
        {
#if __IOS__
            InitSentryCocoaSdk(options);
#elif ANDROID
            InitSentryAndroidSdk(options);
#elif NET8_0_OR_GREATER
            // TODO: Is this working properly? Currently we don't have any way to check if the app is being compiled AOT
            // All we know is whether trimming has been enabled or not. I think at the moment we'll be initialising
            // SentryNative for managed applications when they've been trimmed!
            if (SentryNative.IsAvailable)
            {
                InitNativeSdk(options);
            }
#endif
        }

I finally found answer in this comment

// When we have an unhandled managed exception, we send that to Sentry twice - once managed and once native.
// The managed exception is what a .NET developer would expect, and it is sent by the Sentry.NET SDK
// But we also get a native SIGABRT since it crashed the application, which is sent by the Sentry Cocoa SDK.
// This is partially due to our setting ObjCRuntime.MarshalManagedExceptionMode.UnwindNativeCode above.
// Thankfully, we can see Xamarin's unhandled exception handler on the stack trace, so we can filter them out.
// Here is the function that calls abort(), which we will use as a filter:
