Realm accessed from incorrect thread - Swift 3

Question

At the top of my UITableViewController is the following:

let queue = DispatchQueue(label: \"background\")

When a task is dele

Answer 1

It seems like the write is happening on a different thread than the object was originally accessed from. You should be able to fix it by passing task's id and using that to fetch it from the database right before you do the write (inside the async block).

So at the top:

var taskId = 0  // Set this accordingly

and then something like

self.queue.async {
    autoreleasepool {
        let realm = try! Realm()
        let tempTask = // get task from Realm based on taskId
        realm.beginWrite()
        realm.delete(tempTask)
        do {
            try realm.commitWrite()
        } catch let error {
            self.presentError()
        }
    } 
 }
