To display the name of the method and line number in Swift while printing, you can use the following code:
func printDebug(_ message: String = "", file: String = #file, line: Int = #line, function: String = #function) {
let fileName = file.split(separator: "/").last ?? ""
print("[Debug] \(fileName):\(line) \(function) - \(message)")
}
This code defines a printDebug
function that takes an optional message
parameter, as well as default parameters for file
, line
, and function
. The file
and line
parameters are used to get the name of the file and the line number where printDebug
is called, while the function
parameter is used to get the name of the function.
To use this function, simply call it like this:
printDebug("This is a debug message")
This will print a message like this:
[Debug] MyFile.swift:12 myFunction() - This is a debug message
where MyFile.swift
is the name of the file where printDebug
is called, 12
is the line number, myFunction
is the name of the function, and This is a debug message
is the message passed to printDebug
.
