If you want to print a struct, especially a collection, use dump() instead of print(). The latter prints one long line like this (wrapped here):

[Item(title: "Item 1", age: 10, address: Address(value: "address 1")), Item(title: "Item 2", age: 10, address: Address(value: "address 1"))]

whereas dump() does this:

▿ 2 elements
  ▿ Item
    - title: "Item 1"
    - age: 10
    ▿ address: Address
      - value: "address 1"
  ▿ Item
    - title: "Item 2"
    - age: 10
    ▿ address: Address
      - value: "address 1"

Your feedback is valuable: Do you want more nuggets like this?   Yes   or   No
