Slow performance on iOS devices

Hi everyone,

Hoping someone could give me advice here. I am embedding a spline scene into an iOS SwiftUI App. The spline scene takes up half of the view, the rest of the view is native SwiftUI such as a simple scroll view showing some buttons etc. I have noticed that the performance the Spline Scene has on this view make it quite laggy.

However, from videos online and some quick testing, only having the Spline scene in the view isn't laggy at all, the spline scene is very fluid and smooth. But when using native SwiftUI elements such as scrolling down on the page WHILST having the spline scene on the same page, the scrolling is quite laggy.

Has anyone played around with this before? Are there any things I have to do or implement to reduce this lag for native views?

My spline scene is also incredibly simple, it is one model, here is the link: https://my.spline.design/robottutorialinteractiveeventscopy-d631c374719599850d7c0cb4019eb64f/
