Hi,
I wonder why the Swift compiler does not complain about the
redeclaration of `number` after the guard-statement in top-level code:
// main.swift
import Swift
guard let number = Int("1234") else { fatalError() }
print(number) // Output: 1234
let number = 5678
print(number) // Output: 1234
It looks as if the statement `let number = 5678` is completely ignored.
However, doing the same inside a function causes a compiler error:
func foo() {
guard let number = Int("1234") else { fatalError() }
print(number)
let number = 5678 // error: definition conflicts with previous value
}
Tested with
- Xcode 7.3.1, "Default" and "Snapshot 2016-06-06 (a)" toolchain
- Xcode 8 beta.
Am I overlooking something or is that a bug?
Martin
