swift - print() to console log with color

Question

The code is:

let redColor = "u{001B}[0;31m"
var message = "Some Message"
print(redColor + message)  //This doesn't work
print("(redColor)(message)") //This also doesn't work

and the output would look like this:

[0;31mSome Message

I've also read this post: Color ouput with Swift command line tool, and it doesn't seem to work.

I don't want to use libraries.

Xcode doesn't support console coloring since Xcode 8.

But Since Xcode is fully unicode compatible, you can use emojis instead! for example you can use You can use ?? for warning messages and ?? for error messages. (like the Xcode itself)

Or simply use these note books as a color:

??: error message
??: warning message
??: ok status message
??: action message
??: canceled status message
??: Or anything you like and want to recognize immediately by color

for example:

print("??", "Touch is not disabled as expected")

Using this method will help you to find the logs in the source code as fast as ?? by a simple eye scan:

And you can search for them "????" to let the Xcode take you there. Take a look at this result comparison:

Word search
