Swift problems with addPersistentStore: "expected type before ->"

I can't figure out what is wrong, can someone help me?

coordinator = NSPersistentStoreCoordinator(managedObjectModel: model)
let store = coordinator.addPersistentStore(ofType: NSSQLiteStoreType, configurationName: nil, at: storeURL, options: nil) throws -> NSPersistentStore

It's saying:

expected type before ->

Solution

  • Just remove this final part from your addPersistentStore method call:

    throws -> NSPersistentStore

    and ignore, for now, any exceptions thrown by this method (using a try! before the method call), like this:

    let store = try! coordinator.addPersistentStore(...

    and you should be good :)

    By the way, the return type (and throws qualifier) are only needed on the method definition. They aren't necessary (or even allowed!) when calling a method.
