842 PointsSwift Brackets Syntax. Is there a basic rule for when to use {},[],().
Sorry if this seems silly but as a newbie to programming, I have difficulty remembering when to use the various bracket options when coding. Is there a general rule that can be applied so it makes it easy to remember?

4,162 PointsThere is sort of rules, but at the same time, almost every programming language is different. In swift things that are being used by functions (such as if, else, while, or a custom function) require you put your steps to that function inside of {}. Things like parameters of functions, or things like the print function use (). The [] are mostly used for Arrays and lists. This is a very general list, and there are always exceptions, but I hope this helps, and good luck!
