Shouldn't you have been accessing the subscript value for row before column? the first arg in brackets here `myGrid[1, 1]` would return the first array in the grid. then the second arg would return the actual column, right? Please correct me if im wrong, but I think the row/col logic is backwards in the video

Could you do a video of how to download the pList file from bundle to project ( using new Serialization protocol of swift). Plist file is critical for any project to carry Datasource ( without the need for Json Serialized from server ), yet the video tutorial of this subject is lacking in Youtube... Been looking around for a good tutorial but trusting iOSacademy the most.

I am a Javascript developer and started learning Swift a few weeks ago. But ın my opinion, there are lots of extra things to learn when I compare it to JS. This could be confusing for people who learn it as their first language.

Can you give an example how we can use it in a real life problem? As a developer who has 3 years of experience, most of the times we don't need that level of complexity. Your content is good, dont get me wrong. My problem is about Swift itself 🙂

myGrid[3, 2] returned -1 incorrectly. I changed this line: let maxCol = grid.count. Also same with rowNumbers.count, just dropped the minus 1. Great Video. I'd like to how to code the set method.

Bro just [safe: row] to prevent the crash, there’s no need to do those checks everywhere in the code.
