Xcode8 beta 3: Nested Ternaries operating on optionals in a lazy-var initializer have a fixit that grabs the wrong block to fixup

lazy_optional_ternary_fixit_bug.swift

class Original {
	var opt1: String? = nil
	var opt2: String? = nil
	enum Foo : String {
		case unknown
		case one
		case two
	}
	// Compile flags an error w/ fixit suggestion on line 11 relating to not using optionals directly as booleans
	lazy var type: Foo = {
		return self.opt1 ? .one
			: self.opt2 ? .two
			: .unknown
	}()
}
// This is what Xcode8 Beta 3 produced when applying the fix-it
class FixItCompletion {
	var opt1: String? = nil
	var opt2: String? = nil
	enum Foo : String {
		case unknown
		case one
		case two
	}
	lazy var type: Foo = ({
		return self.opt1 ? .one
			: self.opt2 ? .two
			: .unknown
		}() != nil) /// Now an error highlighting this line
}
// This is the expected result
class ExpectedOutcome {
	var opt1: String? = nil
	var opt2: String? = nil
	
	enum Foo : String {
		case unknown
		case one
		case two
	}
	lazy var type: Foo = {
		return (nil != self.opt1) ? .one
			: (nil != self.opt2) ? .two
			: .unknown
	}()
}
