Summary: I made a mistake in my types and rather than getting useful compiler errors, I started getting Segmentation Fault: 11 errors. Steps to Reproduce: I had much more code but the following snipped illustrates the issue func badTypes() { let sequence:AnySequence = AnySequence() { AnyIterator() { [3] }} let array = [Int](sequence) } I was trying to create an array out of Sequence but had mixed up my types and sequence was actually a sequence of [Int] rather than Int. Expected Results: The second line should generate a compiler error something along the lines of "The type [Int] can't be converted to type Int" or "AnySequence can't be converted to AnySequence " Actual Results: Seg Fault: 11 Version/Build: XCode Version 9.0 (9A235) Configuration: macOS High Sierra 10.13
