I've been stuck on this for days, and despite trying to read the code of other solutions, I can't figure out why my app crashes/hangs the simulator when I click the 'start game' button.

I'm starting to fear I have a big gap in my understanding as to what is going on with passing data between views. Sorry if this is something obvious, I hate asking for help as I feel like I should be able to figure it out by myself, but yeah, totally stuck without any obvious error messages from XCode or the simulator crash.

Hi,

In the GameView Body your missing a point on padding

Thank you so much Hector!!! You are a life saver :-)

PS I think its strange XCode doesnt flag the incorrect .padding() syntax.
