Non Triggering Examples

class Class0 { class Class1 {} }

func func0() {
    func func1() {
        func func2() {
            func func3() {
                func func4() {
                    func func5() {
                    }
                }
            }
        }
    }
}

struct Class0 { struct Class1 {} }

func func0() {
    func func1() {
        func func2() {
            func func3() {
                func func4() {
                    func func5() {
                    }
                }
            }
        }
    }
}

enum Class0 { enum Class1 {} }

func func0() {
    func func1() {
        func func2() {
            func func3() {
                func func4() {
                    func func5() {
                    }
                }
            }
        }
    }
}

enum Enum0 { enum Enum1 { case Case } }

Triggering Examples

class A { class B { ↓class C {} } }

struct A { struct B { ↓struct C {} } }

enum A { enum B { ↓enum C {} } }

func func0() {
    func func1() {
        func func2() {
            func func3() {
                func func4() {
                    func func5() {
                        ↓func func6() {
                        }
                    }
                }
            }
        }
