Summary:
When creating an expression that concatenates a string with inline variables in swift, the compiler will complain that the expression is too complex

error: expression was too complex to be solved in reasonable time; consider breaking up the expression into distinct sub-expressions

Steps to Reproduce:
See attached playground, or use the following code.

let str1 = "Test1"
let str2 = "Test2"
let str3 = "Test3"
let str4 = "Test4"
let str5 = "Test5"
let str6 = "Test6"

var newStr =    "\n Test: \(str1)" +
                "\n Test: \(str2)" +
                "\n Test: \(str3)" +
                "\n Test: \(str4)" +
                "\n Test: \(str5)" +
                "\n Test: \(str6)"


Expected Results:
newStr should be created.

Actual Results:
compiler error
