Hello,

Working my way through the 2nd Tutorial and I’m coming across the following error when trying to call the super. “Property ‘self.row0item’ not initialized at super.init call”. Code below. Can someone point me in the right direction?

Thank you,  
Darin

You have a line of code in that init function starting `let row0item`. This is a local variable - it only exists inside the init function. It’s _not_ setting a value to the property called `row0item` in your type. To do that, you either need to remove the `let`, so you’re only working with the property, or you need to create the local `row0item` variable and assign the result to the type property afterwards (before the super.init) with `self.row0item = row0item` (the ‘self’ is necessary to disambiguate between the two identically named variables).

Thank you! This solved my problem. So it was scope that killed me. ☹
