When I use the NSSet I get this Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)?

Question

Here is my code:

var doneTask = NSSet()
let taskNum = course?.task?.count
let doneTask = course?.value(forKey: "length") as! NSSet

what type of value you are getting from the key "length" – Jogendar Choudhary May 20 '18 at 12:57 — Jogendar Choudhary, May 20 '18 at 12:57
Can you show me the data of course? – Jogendar Choudhary May 20 '18 at 12:58 — Jogendar Choudhary, May 20 '18 at 12:58
