Example
dump prints the contents of an object via reflection (mirroring).
Detailed view of an array:
let names = ["Joe", "Jane", "Jim", "Joyce"]
dump(names)
Prints:
▿ 4 elements
- [0]: Joe
- [1]: Jane
- [2]: Jim
- [3]: Joyce
For a dictionary:
let attributes = ["foo": 10, "bar": 33, "baz": 42]
dump(attributes)
Prints:
▿ 3 key/value pairs
▿ [0]: (2 elements)
- .0: bar
- .1: 33
▿ [1]: (2 elements)
- .0: baz
- .1: 42
▿ [2]: (2 elements)
- .0: foo
- .1: 10
dump is declared as dump(_:name:indent:maxDepth:maxItems:).
The first parameter has no label.
There's other parameters available, like name to set a label for the object being inspected:
dump(attributes, name: "mirroring")
Prints:
▿ mirroring: 3 key/value pairs
▿ [0]: (2 elements)
- .0: bar
- .1: 33
▿ [1]: (2 elements)
- .0: baz
- .1: 42
▿ [2]: (2 elements)
- .0: foo
- .1: 10
You can also choose to print only a certain number of items with maxItems:, to parse the object up to a certain depth with maxDepth:, and to change the indentation of printed objects with indent:.
