ASTraitCollection crash Inserting nil into dictionary

[ay8s]

Believe we're seeing a crash with the latest changes to ASTraitCollection.m in #625. a3136b0

I'm not sure when traits.preferredContentSizeCategory would be nil.

[props addObject:@{ @"preferredContentSizeCategory": (UIContentSizeCategory)traits.preferredContentSizeCategory }];

Edit: Looks to be on rotation of the device.

Just a heads up @ypogribnyi 👍

@ypogribnyi Any idea why this is happening?

[ypogribnyi]

I think it might be possible because of the improper initialization of ASPrimitiveCollectionTraits. I looked through the Texture sources, but haven't found any case of using it without initializing with ASPrimitiveTraitCollectionMakeDefault or ASPrimitiveTraitCollectionFromUITraitCollection().

My version is that this structure might be initialized by the application without using either of those functions and then be given to Texture (it's a struct after all, so zero-initialization is the default).

I tried to fix the crash in #757. @ay8s, can you test if it works for you?

@nguyenhuy I still seem to be facing this when creating logs call through to NSStringFromASPrimitiveTraitCollection
