Hi thank you for developing this amazing framework, making our lives way more easy.

As I start moving to Metal because of OpenGLES deprecation by Apple. I looked into GPUImage3 and MetalPetal. But I realized that MetalPetal is written in ObjectiveC, I wonder if there is a specific reason why is that, since Swift is meant to be the future of Apple software development.

I cant help to wonder, what may happen if Apple slowly switch to Swift ONLY apps in years to come. Would it be wise to write such a complex (and big) framework such as MetalPetal in ObjectiveC right now ?

are there any plans for a Swift rewrite ?

This is just a general doubt, because I wanna be cautious when choosing the right technology (framework/lib) before investing development time in my own long term projects.

Anyways, great job you are doing there. As a second adjacent question.
Are you guys being funded by a larger corporation, or are you powered by Donations, If so it would be great to know how we can contribute.

Cheers
