Accessing a property of an uninitialized instance results in a Runtime error #70908
Closed as duplicate of#70323
Description
Description
The code produces a runtime error instead of a compile-time error. I would anticipate this to be an error that could be identified during compile-time.
It's worth mentioning that removing the print and having just instance.x allows the compiled binary to execute without any runtime errors (exit code 0).
Reproduction
class SomeClass {
let x: Int = 0
}
print(instance.x)
var instance = SomeClass()Expected behavior
I expect this to be a compile-time error
