ANTLR4 Swift grammar cannot identify a for-in statement

[Roy Waxman]

Hello,

I am using ANTLR4 to parse Swift code using the Swift grammar (or at least based on it) from GitHub.

The parser does not identify the for-in statement as a loop statement / for-in statement even if it was defined in the grammar. 

I am trying to understand why.

Thanks, Roy

Hello,

Upon further investigating i did found out the problem was that the parser was wrongly identifying the 'for' as a variable / regular identifier. 

So, i looked in GitHub swift grammar that they indeed separated the identifier to 2 types to avoid such things.

After i did that, the parser identified the for loop statement correctly...

Thanks

Bye
