Example

import Hatch

let source: String = <some swift code>
let symbols = SymbolParser.parse(source: source)
dump(symbols)

Input:

struct A1 {

    struct BC {
        struct C1 {}
        struct C2 {}
        struct C3 {}
    }

    struct BD {
        struct D1 {}
        struct D2 {}
    }

    struct BX {}
}

struct A2 {}

enum MyEnum {}

Output:
