Swift fixing array for notifications -


i'm trying fix notifications displaying every day should pack school next day.

everything seems ok, content.subtitle shows error :

thread 1: exc_breakpoint (code=1, subcode=0x1007dbb00)

is there problem array also? searched answer, looks nobody used array notification body. possible? , if it's not can replace better replacement? help.

let plan = [     ["dzien": "sunday", "lekcje": nil],     ["dzien": "saturday", "lekcje":["pon1","pon2","pon3"]],     ["dzien": "tuesday", "lekcje":["wt1","wt2","wt3"]],     ["dzien": "wednesday", "lekcje":["sr1","sr2","sr3"]],     ["dzien": "thursday", "lekcje":["cz1","cz2","cz3"]],     ["dzien": "friday", "lekcje":["pt1","pt2","pt3"]],     ["dzien": "saturday", "lekcje": nil], ]  func getdayofweek() -> int {     let mycalendar = calendar(identifier: .gregorian)     let weekday = mycalendar.component(.weekday, from: date())     return weekday - 1 }      @objc func registerlocal() {     let center = unusernotificationcenter.current()      center.requestauthorization(options: [.alert, .badge, .sound]) { (granted, error) in         if granted {             print("sukces")         } else {             print("nie dzieła")         }     } }      @objc func schedulelocal() {         let center = unusernotificationcenter.current()          let content = unmutablenotificationcontent()          let d = getdayofweek()%6         let dzis = plan[d]         if dzis["lekcje"] != nil {          content.title = "pack up"         content.subtitle = dzis["dzien"]         var lekcje = ""         lekcja in dzis["lekcje"] {             lekcje+="\(lekcja)\n"         }         content.body = lekcje         content.userinfo = ["customdata": "fizzbuzz"]         } else {          content.title = "tommorow \(dzis["dzien"]), don't have subjects."         }          var datecomponents = datecomponents()         datecomponents.hour = 16         datecomponents.minute = 00         let trigger = uncalendarnotificationtrigger(datematching: datecomponents, repeats: true)          let request = unnotificationrequest(identifier: uuid().uuidstring, content: content, trigger: trigger)         center.add(request)              } }

the problem compiler infers type of plans [string:any] , when trying content.subtitle = dzis["dzien"], dzis["dzien"] of type any , not string.

you have cast string in order work.

guard let subtitle = dzis["dzien"] as? string else {return} content.subtitle = subtitle

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
