Help debugging Thread 1: EXC_BAD_ACCESS (code=1, address=0x28) crash

How do I go about debugging this crash.




With a bit more fiddling around I get this

[error] precondition failure: invalid attribute id: 2189977

AttributeGraph precondition failure: invalid attribute id: 2189977.

And finding similar errors elsewhere I remembered that I changed a NavigationView to a HSplitView (?) which seems to behave the same . After reverting to NavigationView this crash goes away !

Is this a bug? and should I raise a bug with Apple for this ?

Not sure if Apple would call this issue as bug.
But if you have the project which can reproduce the same issue, you should better send a bug report to Apple.
