relates to:

  • SR-10932 Incorrect Error Description For Substrings
  • SR-11702 Misleading Error Message "Subscript 'subscript(_: )' requires the types 'String.Index' and 'Int' be equivalent"

Issue Description:

Two issues were fixed that resulted in the same misleading error message: SR-11702 and SR-10932. But this code still triggers it:

var lines: [String] = []
let line = "this is a line"
lines.append(line[line.startIndex...])

This is the output:

bug.swift:3:18: error: subscript 'subscript(_:)' requires the types 'String.Index' and 'Int' be equivalent
lines.append(line[line.startIndex...])
                 ^
Swift.String:5:12: note: where 'R.Bound' = 'String.Index'
    public subscript<R>(bounds: R) -> String where R : RangeExpression, R.Bound == Int { get }
           ^
