Hello all,
I am at my wits end with this bug and it is one of the last things in my project. I'm sure a feeling all y'all have felt.
I have the issue of when passing data to my child view using observedObjects, the sheet in my child view opens and closes immediately and navigates back to the parent view in its original state. The sheet I am refering to is opens when the button with the scribble symbol is clicked. This is an attempted yelp clone to some extent.
Any help would be much appreciated. Thank you very much.
If someone can give me a solution that works in the context of my code, I will send you $20 in BTC
