crash instantiating native class

[farfromrefuge]

With ios-runtime 6.4.1 i have a crash with a plugin of mine. It works fine with 6.3.0.

the related code is this

this.delegate = HandlerDelegate.new().initWithOwner(new WeakRef(this));

NativeScript caught signal 11.

HandlerDelegate.new().initWithOwner doesn't seem right. new is a shortcut to alloc().init() and calling initWithOwnerfor an already initialized instance is incorrect. I suggest you test with HandlerDelegate.alloc().initWithOwner instead.

This actually may be unrelated to the iOS runtime version, but the device's iOS version. In order to find out the native exception which is being thrown, you may run your app on a real device instead of a simulator, as the callstack suggests you're hitting this limitation of {N} iOS due to libffi breaking the exception rewind mechanism.

@mbektchiev you are write about the naming issue. I already fixed it locally but it is the same error. And as i said it does not crash with 6.3.0. Something changed.

I ll try and run the app on a device thanks!

@mbektchiev I had actually forgot about that issue. Now i faced it again.
Running on a device i get that error:

Class "GestureHandlerEventExtraData" referenced by type encoding not found at runtime.

So i realized it was an issue on my side!

Thanks again @mbektchiev as always!
