Coredata get the entity as message based on get message by id iOS swift

Solution:

func getMessageByID(messageID: String) -> Message?

{

var wgs: [Message] = []

let wgFetchRequest: NSFetchRequest<Message> = Message.fetchRequest()

wgFetchRequest.returnsObjectsAsFaults = false

let predicate = NSPredicate(format: "message_id == %@",messageID)

wgFetchRequest.predicate = predicate

do {

let objects = try getContext().fetch(wgFetchRequest)

wgs.append(contentsOf: objects)

} catch {

customPrint(val:"Error with request: \(error)")

}

return wgs.count>0 ? wgs[0] : nil

}

// MARK: - Get the context

func getContext () -> NSManagedObjectContext {

var context: NSManagedObjectContext?

if #available(iOS 10.0, *) {

context = coredata.persistentContainer.viewContext

} else {

context = coredata.managedObjectContext

}

return context!

}

In above function coredata as the context that initialised in your appdelegate.
