How to use RLMArray to save an Array

Question

Note: I am fairly new to Realm and Swift, so excuse any obvious things I don\'t understand.

I have a working UITableView which I plan to populate with tasks. I want

Answer 1

Realm saves objects derived from RLMObject, so you need to define class for your task like:

@interface Task : RLMObject

@property NSString * task;
@property NSString * description;
@property NSDate * dueDate;
...

@end

RLM_ARRAY_TYPE(Task) // define RLMArray

Then create a task list model as:

@interface TaskList : RLMObject

@property RLMArray * tasks;

@end

Now you create Task, add it to TaskList and save:

RLMRealm * realm = [RLMRealm defaultRealm];
[realm beginWriteTransaction];

Task * task = [Task new];
task.task = @"Some new task";

RLMArray  * tasksLists = (RLMArray  *)[TaskList allObjects];

// You can manage multiple task lists here using unique primary key for each task list. I am assuming that we have only one list.
TaskList * taskList = tasksLists.firstObject;
[taskList.tasks addObject: task];

[realm addOrUpdateObject: taskList];

[realm commitWriteTransaction];

Hope this helps.

Sorry I overlooked that you mentioned you are using Swift.
