ios - '[CLPlacemark]?' is not convertible to '[CLPlacemark]' -> swift2 -

-

this part of code found on stackoverflow.
working in swift 1.2 why code not working anymore in swift 2:

geocoder.reversegeocodelocation(location, completionhandler: { (placemarks, error) -> void in         let placearray = placemarks [clplacemark] // !!! error here !!!          // place details         var placemark: clplacemark!         placemark = placearray[0]          // address dictionary         print(placemark.addressdictionary)          // location name         if let locationname = placemark.addressdictionary["name"] as? nsstring {             print(locationname)         }          // street address         if let street = placemark.addressdictionary["thoroughfare"] as? nsstring {             print(street)         }          // city         if let city = placemark.addressdictionary["city"] as? nsstring {             print(city)         }          // zip code         if let zip = placemark.addressdictionary["zip"] as? nsstring {             print(zip)         }          // country         if let country = placemark.addressdictionary["country"] as? nsstring {             print(country)         }      })

error getlocationviewcontroller.swift:67:41: '[clplacemark]?' not convertible '[clplacemark]'

looks need unwrap placemarks array (implicitly or optional chaining) before assigning type of [clplacemarks]

for example, should use optional chaining so

if let validplacemark = placemarks?[0]{      let placemark = validplacemark as? clplacemark; }

than place logic inside braces if finds valid placemark array, execute desired commands. if not, nothing or can handle please

c# - TransactionScope not rolling back although no complete() is called -

i'm using transactionscope rollback transaction fail bool errorreported = false; action<importerrorlog> newerrorcallback = e => { errorreported = true; errorcallback(e); }; using (var transaction = new transactionscope()) { foreach (importtaskdefinition task in taskdefinition) { loader.load(streamfile, newerrorcallback, task.destinationtable, processingtaskid); } if (!errorreported) transaction.complete(); } i'm sure there no transactionscope started ahead or after code. i'm using entity framework insert in db. regardless state of errorreported transaction never rolled in case of error. what missing ? transactionscope sets transaction.current . that's does. wants transacted must @ property. i believe ef each time connection opened reason. probably, connection open when scope installed. open connection inside of scope or enlist manually. ef has nasty "design decision": default opens
