I'm curious, could you explain to me what exactly $1 in Swift represents? I've heard about Swift being used in the world of finance and cryptocurrency, but I'm not entirely clear on how the value of $1 translates within this context. Is it a specific amount of a certain cryptocurrency? Or does it have a different meaning altogether? I'd appreciate it if you could provide a clear and concise explanation to help me better understand this concept.

For instance, in a closure that takes two String arguments, $0 would represent the first argument, while $1 would represent the second. This naming convention simplifies code readability and enhances maintainability.

The use of these shorthand names is particularly beneficial in scenarios where the closure's body is short and the argument names are not explicitly needed. It eliminates the need for defining separate variable names for each argument.

The shorthand argument names are denoted by dollar signs followed by a number, starting from $0. Each number corresponds to the position of the argument in the closure's parameter list.
