How to implement universal link in ios 9.0 or above?

Using Branch code for universal link implemented in Xcode but no luck lingering around since long plz help.
You need to provide more details about your problem to help you, like error message, code snippet etc, is hard understanding the problem that you have with generic question.
By the way please check apple official content to understand how Universal links works and how to implement this
Reference material:

json2view like solution for iOS

For Android I see there is a very good solution Json2View:
https://github.com/Avocarrot/json2view
for creating Android app UI on the fly. Is there any similar solution available for iOS? Is there any constraint is having JSON based UI concept for iOS, the way json2view does for Android? Or best would be some common open source library that has flavor for both Android and iOS.
Using React Native you can accomplish the same.
Strictly speaking, its not Json to View but its JavaScript to View.
Whatever views you create in ReactJS, will be created using native UIKit Framework.
For example, if you use scrollview component in JS, it will use a scrollview subclassed of UIScrollView.
Please check this link for in-depth overview

You cannot do anything like this, you will get apple rejected because of using any kind of code injection.

Is the iOS "Exclamation" Badge/Button available for use within an App?

I suspect that the answer is 'no' - but perhaps I'm missing something in the api...
I'm aware of the constant UIButtonTypes for UIButton:
http://developer.apple.com/library/ios/#DOCUMENTATION/UIKit/Reference/UIButton_Class/UIButton/UIButton.html
But I've also seen Apple use the exclamation badge within their apps, for example, the Reminders app:
Does anyone know if that button/badge is available?
Or am I making my own?
As I commented, you won't be able to use this button directly.
I don't think you can point to any source to say this, but from my own experience, I never found this button.
But, what you can do, is create or find the button's image. The second option is the easiest one ;)
I found this, giving you all iOS' images (iOS 4.3, but still good) : All stock iOS 4.3 UI Images.
Or you may use directly these normal/selected retina images (comming from the above link) :
And the non-retina versions :
Quick note, you may want to use this button very carefully. As it is a system image, you must use it the way iOS uses it. If you try to use it in an unappropriate context, your app may get rejected by Apple.

iOS calculator project free to include in apps?

I'm wondering if anyone knows of any existing calculator project or library that has a basic calculator view I can push into a navigation stack. So far I haven't found anything that doesn't look like junk.
You should find everything you need there :

http://blog.itopchiyev.com/2008/10/09/hello-iphone/
http://chris-software.com/index.php/2009/04/25/simple-calculator/
https://github.com/rargulati/Simple-Obj-C-Calculator
http://code.google.com/p/obj-c-calculator/source/browse/?r=30#svn%2Fbranches%2FCalculator%20at%20Assignment%201%253Fstate%253Dclosed
http://www.iphonedevx.com/?p=694
You would probably have to adapt some of these in a final app. Check for copyrights, and if one get your heart but cannot be included in your project (do not hesitate to contact the authors, really), rewrite yours from scratch with that inspiration source.
Check out iPhoneCalculator on GitHub, or search for it by keyname.
