Application crashes on -[Invoker invokeSync:method:args:]:

[caleb-kleveter]

I am working on setting up a test application with backendless. I followed the quick start guide here.

When I run the app it crashes on:

-[Invoker invokeSync:method:args:]

I am using Swift 2.2 and Xcode 7.3.1

Hi Caleb,

I have assigned an internal ticket to our iOS dev, soon he’ll contact with you to help you resolve this issue.

Hi Caleb,

I just created a sample project with pod ‘Backendless’ and shared it for you. It works fine for me, please check it and let me know how it goes for you?

HI Slava,

The project you shared worked.

Here is a zip file with the project I created. What did I do wrong?

Hi Caleb,

You made two mistakes:

1. Duplicated ‘secretKey’ == ‘appId’:
   http://support.backendless.com/public/attachments/90f5db1cf378e1bb2f82522734d3e728.png</img>
   but SECRET_KEY should be set by iOS Secret Key of your Backendless app.

2. If you use a sync method, you should use try/catch wrapper (I fixed ViewController.swift of your sample):

class ViewController: UIViewController {
 
 let backendless = Backendless.sharedInstance()

 override func viewDidLoad() {
 super.viewDidLoad()
 
 registerUserSync()
 }
 
 func registerUserSync() {
 
 Types.tryblock({ () -> Void in
 
 let user = BackendlessUser()
 user.email = "caleb.kleveter@gmail.com"
 user.password = "my_super_password"
 
 let registeredUser = self.backendless.userService.registering(user)
 print("User has been registered: \(registeredUser)")
 },
 
 catchblock: { (exception) -> Void in
 print("Server reported an error: \(exception as! Fault)")
 }
 )
 }

}

Cause of your original sample crash was “uncatched exception”.
