Product:Developer Tools Product Version:Xcode 6.2 (6C131e)
Classification:Serious Bug Reproducible:Always
 
Summary:
The swift parser fails to parse a string that uses a string interpolation segment that contains a string literal (in the form of a “ character)

Steps to Reproduce:
Attempt to compile the following swift code:

let property = "property"
let ascending = false

let string = "SortDescriptor (property: \(property), direction: \(ascending ? "ascending" : "descending"))"


Expected Results:
string == “SortDescriptor (property: property, direction: descending)”

Actual Results:
Error: Unexpected ‘“‘ character in string interpolation

Regression:
This error occurs in both Swift 1.1 and 1.2
