Come back to the tabBarController, swift

Question

Currently on my viewController : Upload, my button send the data to my database only if all the information are filled out, and I come back to the preview view (table View) with :
self.navigationController?.popViewControllerAnimated(true)

I would like, if it is possible, to come back to my main view on the tabBarController. I tried many things, like directly on the storyboard with Present modally segue to "TabBar controller", but I come back to the TabBar without sending my data to the database and without checking in the information are filled out..

How can I do it?

Thanks!

UITabBarController has a property selectedIndex with which you can switch the selected tab. So on completion after dismissing the UploadViewController you can run:

self.tabBarController?.selectedIndex = 0 // Index to select

It would probably be best to create a delegate for your UploadViewController to fire a function to do all the work in your previewVC on API call completion.

(Super late response...in case someone has similar questions, presumably in later version of Swift, such as mine which is Swift 5, iOS 13.2). Steps:

Be sure to set an id for your UITabBarController storyboard, e.g. "TabBarViewController"
Next, add the following to an action that has already been connected to a button:

let ID_TABBAR = "TabBarViewCOntroller"

@IBAction func returnToTabbar(_ sender: Any) {
        let tabBarController = self.storyboard?.instantiateViewController(identifier:ID_TABBAR) as! UITabBarController
        self.navigationController?.pushViewController(tabBarController, animated:true)
}

Referenced from one of the responses from this post.

Update: In case your Tab Bar View Controller also happens to be the root view controller, the two lines of the code in the returnToTabbar method above can be:

self.dismiss(animated:true, completion:nil);
self.navigationController?.popViewController(animated:true);

(ref.: See answer here, for Swift4 but works just fine in Swift5)

Come back to the tabBarController, swift
