Class to table mapping for custom service

[David_Delagneau]

I’m trying to get objects from the backend and map them to classes defined in Swift from the SDK BackendlessSwift v6.0.4.1 so simliar to Android however I cannot find this functionality from customService.invoke topic relationed

• App ID: BAFA98AD-EB6A-DCBD-FF35-67E7A51C7300
  • 
• Sample client code:

@objcMembers 
        class Person : NSObject {
            var age: Int?
            var name: String?
        }
        let response = { (data: Any?) -> Void in
            print("--------------")
            print(data as! Person)
            print("--------------")
        }
        let errorHandler = { (error: Fault) -> Void in
            print(error)
        }
        Backendless.shared.customService.invoke(serviceName: "test", method: "get", parameters: nil , returnType: Person.self, executionType: .sync, responseHandler: response, errorHandler: errorHandler) 

• Exception: Could not cast value of type 'Swift._SwiftDeferredNSDictionary<Swift.String, Any>'

Hello @David_Delagneau,

Your Person table has the age property of type INT, and you’re trying to make it String:

class Person : NSObject {
    var age: String?
    var name: String?
}

Your code will work fine if you change the age property to Int:

@objcMembers class Person : NSObject {
     var age: Int = 0
     var name: String?
 }

I made the change (age: Int = 0) but I get the same exception Could not cast value of type 'Swift._SwiftDeferredNSDictionary<Swift.String, Any>' checking the source code .invoke receives the type of object to return but does not do extra processes to transform it

@olhadanylova I can see class based approach from ‘database store’ but not in custom services

Could you please share your archived project here because I cannot reproduce this issue and your code works fine for me.

Thank you very much @olhadanylova I have already noticed my error, it is that I defined the @objcMembers within another class
