unrecognized selector sent to instance

[farfromrefug]

With the v8 runtime and the latest {N} my app crashes with this:

-[UIView transform3D]: unrecognized selector sent to instance 0x7fb8f47462f0

I am running on an ios 12 simulator .

It is for a view i apply a translate to. Thus i think the crash happens here:
https://github.com/NativeScript/NativeScript/blob/master/nativescript-core/ui/core/view/view.ios.ts#L372

It is not happening with 6.4.1

Did you try running this on an iOS 13 simulator?

The following objective-C code crashes with unrecognized selector on iOS 12 and works fine on iOS 13:

CATransform3D a = [view transform3D];

So the availability attribute of this property seems to be wrong in the SDK:

@property(nonatomic) CATransform3D transform3D API_AVAILABLE(ios(12.0),tvos(12.0)); 

I guess you should not be using this property if you intend to target devices with iOS lower than 13.

@darind it works on the 13.0 simulator, crashes on the 12.0
And i am not using that prop, {N} is ;)
But why is the 6.4.1 runtime working.
Can it be a question of metadata? like you expect transform3D to be a property, which it is not on 12.0, and the older runtime does not expect anything, so it does not crash as it sees that as just an undefined prop from JS (if you see what i mean).

@farfromrefug, that's correct. In addition to the availability attributes, the old runtime also applies logic if the instance responds to the corresponding selector. The reason for this is because there are inconsistencies in the iOS SDK like the one you have encountered.

I will apply the same check in the new runtime as well.

@farfromrefug, we have released a fix under the beta-v8 tag. Please let us know if this works in your app.

@farfromrefug, did you have the chance to check the released fix?

@darind sorry for the late reply. I ran a quick test and it seems to work perfectly!
Thanks
