Hello, I simply tried the statement
var a = 🙉
in a new iPhone/iPad Swift Project, and I get the error from the Xcode text editor: "cannot find 🙉 in scope" I suppose there is an option somewhere in the Project parameters which enables emojis ... but where ? thank's for any clue!
When you write
var a = 🙉
🙉 is an identifier of an object. But you did not declare it.
If you want to assign an emoji (String) to a, you have to write
var a = "🙉"
But you could also declare a var:
var 🙉 = "Hello, I am an emoji"
And then
var b = 🙉
Fine! I was guessing an emoji was a sort of predefined 4 bit integer ... which obvious it isn't. But things are clear for me now. Great. Tanks a lot!
