I am using a blank core data proj and trying to copy the code from this examples.
https://www.and rewcbancroft.com/2015/02/18/core-data-cheat-sheet-for-swift-ios-developers/
As there is no managedContext i am not able o proceed.
I am new to IOS programming. Please can anybody share me a simple example that i can start with. But i need it with Xcode8 beta4 version. I tried many other examples but once i convert them to my current version they are not working.
The error message reads:
Value of type 'ViewController' has no member 'managedObjectContext'
What this means is that somewhere (your screenshot does not show where) you are attempting to assign a value to a property named managedObjectContext
, on an instance of your ViewController
class. Except that this class doesn't have a property named managedObjectContext
, so Swift complains and doesn't compile.
This is not actually a Core Data question-- it's basic Swift. It would happen for any attempt to assign a value to a nonexistent property.
You probably (again, your screenshot does not provide enough detail to be sure) need to create this property on your view controller class, with type NSManagedObjectContext
.
