swift pareser in go

[OmarEldeeb98]

I am trying to generate swift5 parser in golang but after generating it
swift5_parser.go and swift5_lexer.go have many error
i have downloaded Swift5Lexer.g4 and Swift5Parser.g4 and ran
antlr4 -Dlanguage=Go -o output-directory Swift5Lexer.g4 Swift5Parser.g4
one of errors in swift5_parser.go in func (p *Swift5Parser) Statements() (localctx IStatementsContext)
all fucctions of p are undefined

• This grammar is in grammars-g4 https://github.com/antlr/grammars-v4/tree/8e1413efb04f0bf97aea5674cf8d18e970972934/swift/swift5.
• There is no Go port of the grammar. https://github.com/antlr/grammars-v4/blob/8e1413efb04f0bf97aea5674cf8d18e970972934/swift/swift5/desc.xml#L4
• It takes a lot of time and effort to write a port for a grammar, which is why it doesn't exist.

i have generated kotlin parser in go and it works well, in spite that target in desc.xml in case of kotlin is empty, https://github.com/antlr/grammars-v4/blob/master/kotlin/kotlin/desc.xml
why is that different to swift5 parser ?
thank you

Thanks for letting me know about the kotlin grammar desc.xml. I'm not sure why there are no targets specified in the desc.xml. That seems like an error. But, there are some errors for examples/script/preable_nl.kts, probably because there is no newline on line 6. Maybe that is why I removed the targets.
