I created this UIPickerView where the 1 components selection decides what the 2 components data is. Yet, whenever I start moving the UIPicker it throws the "libc++abi.dylib: terminating with uncaught exception of type NSException" error with Thread 1. I am guessing the data is the problem?? Not Sure

Update
This start going crazy. Once I start moving the second component it start changed the 1st component until it throws a "index out of range" on the "businessType.text = secondColumnData[selected][row]" I just tried changing the positions of the business category label but not working
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if component == 0 {
pickerView.reloadComponent(1)
} else {
let selected = pickerView.selectedRow(inComponent: 1)
businessType.text = secondColumnData[selected][row]
}
businessCategory.text = categories[row]
}
EDIT added text labels
func pickerView(_ pickerView: UIPickerView, didSelectRow row: Int, inComponent component: Int) {
if component == 0 {
pickerView.reloadComponent(1)
} else {
let selected = pickerView.selectedRow(inComponent: 0)
businessCategory.text = categories[selected]
businessType.text = secondColumnData[selected][row]
}
}
