Error

func fetchingFirstPageAsync() {

print("\n============ Fetching first page using the ASYNC API ============")

let startTime = NSDate()

let query = BackendlessDataQuery()
backendless.persistenceService.of(Restaurant.ofClass()).find(
query,
response: { ( restaurants : BackendlessCollection!) -> () in
let currentPage = restaurants.getCurrentPage()
print(“Loaded (currentPage.count) restaurant objects”)
print(“Total restaurants in the Backendless starage - (restaurants.totalObjects)”)

for restaurant in currentPage as! [Restaurant] {
print(“Restaurant name = (restaurant.status)”)
}

print(“Total time (ms) - (1000*NSDate().timeIntervalSinceDate(startTime))”)
},
error: { ( fault : Fault!) -> () in
print(“Server reported an error: (fault)”)
}
)
}
I am very confused right now , i have created a new project and tested this and it works but in my current app i test it and it gaves me this error ============ Fetching first page using the ASYNC API ============
Loaded 4 restaurant objects
Total restaurants in the Backendless starage - 4
fatal error: NSArray element failed to match the Swift Array Element type
(lldb)

I have no idea why it the same code

Hi Khoo,

Please try this sample:

class Location : NSObject {

    

    var objectId : String?

    var created : NSDate?

    var updated : NSDate?

    

    var ownerId : String?

    var phoneNumber : String?

    var streetAdress : String?

    var city : String?

}



class Restaurant : NSObject {
    
    var objectId : String?
    var created : NSDate?
    var updated : NSDate?
    
    var ownerId : String?
    var name : String?
    var cuisine : String?
    var locations : [Location]?
    var owner : BackendlessUser?





















}




class ViewController: UIViewController {
 
 let APP_ID = "CF47722D-EB7B-A0D0-FFE3-1FADE3346100"
 let SECRET_KEY = "43B43EF7-247A-ED56-FF2F-ECD43C6E9000"
 let VERSION_NUM = "v1"
 
 var backendless = Backendless.sharedInstance()
 
 override func viewDidLoad() {
 super.viewDidLoad()
 
 backendless.initApp(APP_ID, secret:SECRET_KEY, version:VERSION_NUM)
 
 fetchingFirstPageAsync()
 }
 
 func fetchingFirstPageAsync() {
 
 print("\n============ Fetching first page using the ASYNC API ============")
 
 let startTime = NSDate()
 
 let query = BackendlessDataQuery()
 backendless.persistenceService.of(Restaurant.ofClass()).find(
 query,
 response: { ( restaurants : BackendlessCollection!) -> () in
 let currentPage = restaurants.getCurrentPage()
 print("Loaded \(currentPage.count) restaurant objects")
 print("Total restaurants in the Backendless starage - \(restaurants.totalObjects)")
 
 for restaurant in currentPage as! [Restaurant] {
 print("Restaurant name = \(restaurant.name)")
 }
 
 print("Total time (ms) - \(1000*NSDate().timeIntervalSinceDate(startTime))")
 },
 error: { ( fault : Fault!) -> () in
 print("Server reported an error: \(fault)")
 }
 )
 }
}

Here is my app:

Here is a log of the code above:
http://support.backendless.com/public/attachments/785eb32d0a4b87c6fa7ffa0674f7e26f.png</img>
So, I cannot reproduce this issue.
Please add here YOUR class ViewController implementation demonstrating the problem.
