I'm interested in replicating the transition features in the picture below.
I have noticed this being used in multiple apps but am not sure where to start.
The transition literally pushes the current screen away in a direction and is followed by the requested screen. In the picture below, the paper plan button is pressed to initiate this transition
Does anyone know how to create this custom segue or does anyone know of any projects on Github that demonstrate this?
Thanks in advance!
its not a segue you would use. you would use the childViewControllers property of UIViewController to add left and right view controllers than do some animation tricks and gesture recognizers to get it how you want it to look. There are tons of tutorials online just look them up if you don't want to come up with one from scratch.

So I'm trying to imitate the transition found in the Pocketcasts app. The idea is to have a view controller emerge from the bottom of the screen when an item is clicked on, and the view controller can either be swiped up to go full screen or swiped downwards to dismiss it. I honestly have no idea how I would achieve this, so I'm wondering if anyone has dealt with it before. Ideally this would be done in Swift, but Obj-C works. Thanks!
There is a really great video from WWDC 2017 that builds a similar component using UIViewPropertyAnimator. This allows for interruptible animations as shown in your gif.
The presentation is extremely well done, and provides sample code.

As simple as this question may seem, I just couldn't figure it out. To the overflow community, I am using sprite kit to create a simple game, However when you lose the game I want to programmatically segue back to another viewController (basically the home screen). from The game scene I do not get access to "performSegueWithIdentifier" I've seen a couple answers that relate to this topic however non of them are in swift ... Any solutions?

Thank You
I think you are misunderstanding SKViews. SKViews are just like a normal UIViews, they take place within a normal ViewController. You will therefore need to segue from the ViewController which is presenting your SKView.
I have the same issue in a game I have created (Ninja-Shooter). In my game, whenever I want to segue back the home screen I pass a value to NSUserDefaults.standardUserDefaults(). Then in my ViewController I am constantly listening for any change in that value, if the value does change, then I perform a segue.
Hope this helps!
I have discovered that using NSNotification Center Can in fact derive the results I was looking for. If any one in the future needs detailed code I will edit to provide that
So im not new to xCode, been coding for awhile, but recently I've been looking into custom segues. So i was able to easily create a left/right sliding segue, but i was wondering how to get it to track finger sliding, similar to how whatsapp's segue works. so like the more i slide my finger to the left/ right, the more of the destination view controller is shown, and less of the source view controller. (objective c) (swift example will be helpful too).
Appreciate the help.
This approach is called sidebar navigation. A lot of examples are available online.
At least, you can refer to:

I've been using UIPageViewController with transitionStyle UIPageViewControllerTransitionStyleScroll in order to be able to easily move between views in my app.
I'm looking for a bit more functionality that I won't get from the UIPageViewController so I'm looking to make my own solution - perhaps still a subclass of UIPageViewController.
To explain the extra functionality I'll provide a scenario & a diagram:
In A the app is currently showing the first view controller. I then drag from right to left which will of course start to show the second viewcontroller as shown in B. If I stop panning before the point where the UIPageViewController decides whether or not to show the second view controller or go back to the first one I'd like it to instead show the second viewcontroller (taking up one third of the screen) instead of hiding it completely.
If I was to keep panning a bit further beyond the halfway point and then released I'd like the second view controller to take up two thirds of the screen, while the first view controller takes up one third.
That's essentially it. I'd appreciate any advice on how to go about doing this. I'm thinking I'll subclass UIPageViewController and override the delegate methods, but I'd really appreciate any advice on a better solution.
Many thanks
Maybe this could give you a hint or and inspiration. >>

I've seen quite a few apps doing this, one in particular the facebook app when the more button on the top left is tapped.
I'm not sure what this is called exactly and my hunt for the answer has been unsuccessful.
Help appreciated
Kind regards
