Summary:
Using the “…” and “..<“ operators to get a slice of an array raises EXC_BAD_INSTRUCTION in Xcode 7 beta 6.
Steps to Reproduce:
1. Put the following code in a new playground or iOS:
var shoppingList = ["Eggs","Milk"]
shoppingList.append("Flour")
shoppingList += ["Baking Powder"]
shoppingList += ["Chocolate Spread", "Cheese", "Butter"]
shoppingList.count
shoppingList[4...6]
Expected Results:
The output of the last statement should be ["Chocolate Spread", "Cheese", "Butter"]
Actual Results:
The output is an error: “Execution was interrupted. Reason: EXC_BAD_INSTRUCTION (code=EXC_i386_INVOP, subcode=0x0).”
Regression:
This worked in Xcode 7 beta 5 and doesn’t work in Xcode 7 beta 6.
Notes:
Please note that this fails the same way when using the “..<“ instead of “…”.
