Re: New syntax in Xcode 12.5.

1. myVar != someValue is the condition.

2. It determines whether the ternary expression evaluates to resultOne or resultTwo

3. resultOne or resultTwo is what is assigned in let myVar =

This seems like a standard use of the ternary conditional operator. I don’t have any problems compiling it in Xcode 12.4.

The first half. Ternary has been there since time began. I’ve never seen this part be legitimate before.

let myVar = myVar != someValue

Are you referring to the ternary conditional operator, which has existed in Swift since the beginning, or to the fact that it creates a local variable with the same name (myVar) as a parameter or member (myVar)?

I just saw someone use this syntax in a project and haven’t see it before. It compiles in Xcode 12.5, but not in Xcode 12.4. Does anyone have any more details on it?

let myVar = myVar != someValue ? resultOne : resultTwo

Swift sure is getting muddier and muddier with regards to visual comprehension.

Thanks in advance.
