Started getting this error on Beta 5, while drawing a path taken from a user gesture.

Doesn't always happen, never had this problem on iOS 13 or even Beta 3. (did not try 4).

The position is not NaN, same code works on Beta 3

** Terminating app due to uncaught exception 'CALayerInvalidGeometry', reason: 'CALayer position contains NaN: [nan nan]. Layer: <TtC7SwiftUIP33F176A6CF4451B27508D54E2BEAEBFD5415ColorShapeLayer:0x6000033efa80; position = CGPoint (0 0); bounds = CGRect (0 0; 0 0); delegate = <TtC7SwiftUIP33A34643117F00277B93DEBAB70EC0697122UIShapeHitTestingView: 0x7fa7c4e1f2c0; frame = (0 0; 0 0); anchorPoint = (0, 0); autoresizesSubviews = NO; layer = <TtC7SwiftUIP33_F176A6CF4451B27508D54E2BEAEBFD5415ColorShapeLayer: 0x6000033efa80>>; allowsEdgeAntialiasing = YES; allowsGroupOpacity = YES; anchorPoint = CGPoint (0 0); lineDashPattern = (

terminating with uncaught exception of type NSException

Any ideas?

I have a similar problem, also no idea what is wrong, I don't see any Nan in the log

CALayer position contains NaN: [nan nan].

Same issue when trying out beta 5. Works fine with beta 2 or current release version of Xcode

I've been seeing the same issue occasionally since iOS 13. Typically after doing something like:

Present UIViewController that uses UIHostingController
Dismiss
Present again
Crash

But also sometimes on the first presentation. It will happen one or two times in a row, then disappear for days. Seems random.
