| Classification: | Serious Bug | Reproducible: | Always |
Summary:
Using Swift’s for/in syntax with an NSEnumerator crashes the compiler (and SourceKitService).
Steps to Reproduce:
1. Try to compile this code:
let enumerator = NSArray(array: [ "one", "two", "three" ]).objectEnumerator()
for each in enumerator {}
Expected Results:
I expected it to compile, or to give me an error explaining why it can’t.
Actual Results:
It crashed.
Regression:
N/A
Notes:
This doesn’t occur when using for/in with an NSArray, so I have to assume that the problem is with NSEnumerator and not e.g. NSFastEnumeration.
