Swift ⟩ statement ⟩ do

a statement that is used to introduce a new scope and can optionally contain one or more catch clauses, which contain patterns that match against defined error conditions. (similar to curly braces ({}) in C used to delimit a code block)

🧨 雷區

⛔ error: unlabeled break is only allowed inside a loop or switch, a labeled break is required to exit an if or do. ( 👉 see: for...in vs. forEach )
