iOSKit PickerViewMultiline crashes app in Opening Event

Mark_Sweeney · May 25, 2022, 4:43pm

When I use the following code to set up the PickerViewMultiline, the app crashes on the first line. It does this in 2021 R3.1 and 2022 R1.1

I was hoping to use this to change font sizes as the PickerView uses ginormous fonts.

Me.AddColumn(Array("One","Two","Three","Four"))

Me.Invalidate
Me.SelectedRowInColumn(0) = 1

Can you provide a crash log?

Here’s the crash log. Happens on device, and in the simulator on my M1 Mac mini.
