I am having trouble parsing this JSON, with the nested arrays. I am trying to get to the definition under "text" in "dt". The current output is something like this, while I am just trying to get to the definition:
["text", "{bc}to emit puffs (as of breath or steam)"]
["text", "{bc}to make empty threats {bc}{sx|bluster||}"]
["text", "{bc}to react or behave indignantly"]
for result in jsonArray {
if let def = result["def"] as? JsonArray {
for defItem in def {
//print(defItem)
if let sseq = defItem["sseq"] as? [Any] {
for _1 in sseq {
if let _1arr = _1 as? [Any] {
for _2 in _1arr {
if let _2arr = _2 as? [Any] {
for _3 in _2arr {
if let res = _3 as? JsonDict {
if let definitions = res["dt"] as? [[String]] {
print(definitions[0])
}

As #Robert pointed out, this JSON is in a bad place. As a fun thought exercise here's what you can do.
Formatted json:
{
"def":[
{
"sseq":[
[
[
"sense",
{
"sn":"1",
"dt":[
[
"text",
"{bc}a set of the equipment used in a particular activity {bc}{sx|gear||} "
],
[
"vis",
[
{
"t":"fishing {wi}tackle{/wi}"
}
]
]
]
}
]
]
]
}
]
}
Meet Swift Codable:
let woah = try? newJSONDecoder().decode(Woah.self, from: jsonData)
// MARK: - Woah
struct Woah {
let def: [Def]
}
// MARK: - Def
struct Def {
let sseq: [[[SseqElement]]]
}
enum SseqElement {
case sseqClass(SseqClass)
case string(String)
}
// MARK: - SseqClass
struct SseqClass {
let sn: String
let dt: [[DtUnion]]
}
enum DtUnion {
case dtClassArray([DtClass])
case string(String)
}
// MARK: - DtClass
struct DtClass {
let t: String
}
