I have had a suspicious crash in my app for a long time. I'm 95% using SwiftUI and have to use only one UIKit view that I embed into SwiftUI in my app.
I don't understand why my app crashes when the CALayer position is set to Nan because I don't reference layers at all, including that UIKit view.
Any ideas why it may happen and how can I reproduce it?
Fatal Exception: CALayerInvalidGeometry
CALayer position contains NaN: [nan nan]. Layer: <CAShapeLayer:0x303cd9600; position = CGPoint (0 0); bounds = CGRect (0 0; 0 0); delegate = _NoAnimationDelegate; allowsGroupOpacity = YES; anchorPoint = CGPoint (0 0); >

I'm using Xcode Cloud for release builds and unit tests, and it works fine. Recently, I added some XCUITests, but to run it the way I need I started to use this mock server. Basically, the idea is you define before each test what responses you want to get for specific requests. It works like a charm locally. But if I want to run it in Xcode Cloud, it looks like the server has failed to launch. The mock server is a separately launched binary file. I think this is because this permission I get when launch it locally.
So, my question is how to allow this kind of permission in Xcode Cloud to make my UITests works correctly?
You can find a detailed instruction how server is launched on a github page I provided.
