So your code could look like that : var key = "keySave" Even though Apple bridges types such as String and NSString, I wasn't able to save an array of neither of. I have the same problem as you, as to know, the array of String is not saved. Just to add on to what says in the comments. As far as I know, anything that you can save in a property list will work like this. As you can see, the basic setup was the same for Int, Bool, and Date.It means that if the object returns nil, then the value following the ? operator will be used instead. The nil coalescing operator ( ?) allows you to return the saved array or an empty array without crashing.Attempt to set a non-property-list object as an NSUserDefaults.Table views are data-driven, normally getting their data from a data source object that you provide. Xcode creates a new scene that includes both the view controller and a table view, ready for you to configure and use. Save custom objects into NSUserDefaults To add a table view to your interface, drag a table view controller ( UITableViewController) object to your storyboard.

See the following links for how to do it. Let array = defaults.array(forKey: "SavedDateArray") as? ()Ĭustom objects (and consequently arrays of objects) take a little more work to save to UserDefaults. Let array = defaults.array(forKey: "SavedBoolArray") as? ()ĭt(array, forKey: "SavedDateArray") Let array = defaults.array(forKey: "SavedIntArray") as? ()ĭt(array, forKey: "SavedBoolArray") Let myarray = defaults.stringArray(forKey: "SavedStringArray") ?

loadedCart (forKey: 'cartt') as String: Any tableView.reloadData() In numberOfRows return.

var loadedCart String:Any() In viewDidLoad load the data from UserDefaults and reload the table view. Relaunch the app to load data from UserDefaults again. Declare a data source array on the top level of the class. I found a weird behavior when using UserDefaults to save/load data, what I do as below. For those people I will add a few common examples. Sometimes, UserDefaults reloads the deleted data after relaunching the app. Also, dont store your array in UserDefaults, its for. Suppose you load the data from persistent storage.

I'd appreciate any critiques and suggestions anybody has for me.The question reads "array of array" but I think most people probably come here just wanting to know how to save an array to UserDefaults. The general idea would be on add button tap (or whatever event listener you want to attach the action to), save it to persistent storage, reload your tableView, since the dataSource is from persistent storage, itll update automatically.

I didn't explicitly adopt the UITableViewDataSource or UITableViewDelegate protocols which I have to have specified, yet it still works.

You can store some basic data such as Default volume or Login Credentials so that you dont have to login every.

the refresh() function: I struggled to figure out a way to set the upper range in the for loop. User Defaults is very useful tool in iOS Xcode.

This code works, but there are a couple of areas that just don't feel right: I'm a beginner programmer and new to Swift. The selected lift name is then set as the new default value and will be included in the lift log if the user chooses to save it (in another view). let defaults NSUserDefaults.standardUserDefaults() let defaultValues 'selectedCells' : String() defaults. When the user selects a lift name, the refresh() method is called which places a checkmark on that selected item. There are two sections in the tableview, top one is followedArray and second is mainArray which is where all the objects are after being in jsonArray. I expect to update this database everyday. This particular view controller presents a list in a tableView of all types of lifts a user can choose from to set as a default preference. The app works by me inputing data into the mysql database which is sent using php and received with json and swift 3 to populate the tableview. This is the Swift code from one of the view controllers in my app that calculates a one rep maximum weight a person can theoretically lift.
