Issue with get property in user table

iOS
1

If I logged in with social account To fetch record using getproperty(category), I am getting the error - NsArray element failed to match the swift Array Element type.
*Category is the related to other table
*There won’t be any issue if I logged in with manually registered user.

Did you login with easyLoginFacebook or with loginWithFacebookSDK?

Could you give us some your code?

I used “backendless.userService.easyLoginWithFacebookFieldsMapping” to Login with Facebook

Please check the below code

class UserAndCategoriesMapping : BackendlessEntity {

var categoryID : Int = 0

}

func getUserSelectedCategories(user : BackendlessUser, callback : GetUserSelectedCategoriesCompletionBlock){
    
    if(user.getProperty("categories") is NSNull){
        print("getProperty(categories) is nil")
        callback(categories: [], error: nil)
        
        return
    }
    
    let userAndCategoriesMappingArray = user.getProperty("categories") as! [UserAndCategoriesMapping] /* here we can get array count but if i try to get the value will crash

po userAndCategoriesMappingArray.count

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #000000}
span.s1 {font-variant-ligatures: no-common-ligatures}

po userAndCategoriesMappingArray[0]

p.p1 {margin: 0.0px 0.0px 0.0px 0.0px; font: 11.0px Menlo; color: #000000}
span.s1 {font-variant-ligatures: no-common-ligatures}
