Compilation errors in xCode 7 + Swift 2.0

Question

Since I have installed the xCode 7 beta2 + Swift 2.0, I'm getting some errors in my app. For example, I'm getting the following error

"Cannot invoke 'requestAccessToEntityType' with an argument list of type '(EKEntityType, completion: (Bool, NSError!) -> _)'

in this part of code:

eventStore.requestAccessToEntityType(EKEntityType.Event,
    completion: {(granted: Bool, error:NSError!) in
            if !granted {
                print("Access to store not granted")
            }
    })

Also this error:

Cannot invoke 'predicateForEventsWithStartDate' with an argument list of type '(NSDate, endDate: NSDate, calendars: [AnyObject])'

in this part of code:

calendarsPrueba.addObject(calendarWithName("US Holidays")!)
var predicate2 = eventStore.predicateForEventsWithStartDate(startDate, endDate: endDate, calendars: calendarsPrueba as [AnyObject])

Do somebody know how to fix this issues? There's no Apple documentation about this

Answer 1

Same question as @HAS had - did you run the migrator? Lot of incompatible changes between Swift 1.2 and Swift 2.0. Code must be migrated or manually fixed.

requestAccessToEntityType

Error ...

Cannot invoke 'requestAccessToEntityType' with an argument list of type '(EKEntityType, completion: (Bool, NSError!) -> _)'

... is there because your type is (Bool, NSError!) -> Void instead of (Bool, NSError?) -> Void. Replace NSError! with NSError? to fix it.

Check documentation, signature is:

typealias EKEventStoreRequestAccessCompletionHandler = (Bool, NSError?) -> Void

predicateForEventsWithStartDate

Cannot invoke 'predicateForEventsWithStartDate' with an argument list of type '(NSDate, endDate: NSDate, calendars: [AnyObject])'

Signature is:

func predicateForEventsWithStartDate(_ startDate: NSDate,
  endDate endDate: NSDate,
  calendars calendars: [EKCalendar]?) -> NSPredicate

With your as [AnyObject] you're trying to pass [AnyObject] instead of [EKCalendar]. To fix this, declare calendarsPrueba as:

var calendarsPrueba: [EKCalendar]

And do not cast it to [AnyObject].

There is. Always read release notes, where you can find summary of all changes. And then recheck documentation, because as I wrote, you can find many significant changes between Swift 1.2 and Swift 2.0.

this works with Xcode 7 / swift 2:

final func addToCalendar(){

    let eventStore = EKEventStore()
    eventStore.requestAccessToEntityType(EKEntityType.Event, completion: { (granted, error) in
        if !granted {
            // Show alert...
            print("Access not allowed")
            print(error!.localizedDescription)
        }
        else {
            print("Access granted")
            let event = EKEvent(eventStore: eventStore)
            let uuid = NSUUID().UUIDString
            event.title = "sample Event " + uuid
            event.startDate = NSDate();
            event.endDate = event.startDate.dateByAddingTimeInterval(60*60)
            event.calendar = eventStore.defaultCalendarForNewEvents

            do {
                try eventStore.saveEvent(event,  span: .ThisEvent)
            } catch let error as NSError {
                print(error.localizedDescription)
            }
        }
    })
