  • SR-5355 "Cannot override non-throwing initializer with throwing initializer"

Issue Description:

class Foo {
    init() {}
}

class Bar: Foo {
    override init() throws {
        //if something goes wrong, throw error
        super.init()
    }
}

which produce "Cannot override non-throwing initializer with throwing initializer"

I can workaround this by

class Foo {
    init() {}
}

class Bar: Foo {
    init(_ comeOn: Int? = nil) throws {
        //if something goes wrong, throw error
        super.init()
    }
}

This is really exactly the same as SR-5355. We don't need two bugs for it.
