Handle updating SnapKit constraints semi-automatically when keyboard is shown/hidden 📱

SnapKit-Keyboard

Handling keyboard appearing/disappearing in SnapKit.

How to use it?

In viewDidLoad or other initializing place in code call view.registerAutomaticKeyboardConstraints().

override func viewDidLoad(){
    view.registerAutomaticKeyboardConstraints()
}

Then while adding constraints add .keyboard(false, in: view) to constraints in make or remake to deactivate them automatically when keyboard appears.

topView.snp.makeConstraints { (make) in
   make.left.equalTo(view.snp.left)
   make.right.equalTo(view.snp.right)
   make.top.equalTo(view.snp.top).keyboard(false, in: view)
   make.height.equalTo(100)
}        

As for constraints you want to keep/install when keyboard appears call .keyboard(true, in: view) on them in .snp.prepareConstraints.

topView.snp.prepareConstraints { (make) in
   make.bottom.equalTo(view.snp.top).keyboard(true, in: view)
}

If your view is launching with keyboard already shown - you should switch .makeConstraints with .prepareConstraints so that .makeConstraints constains code for keyboard shown constraints and .prepareConstraints should in that case contain code for keyboard hidden.
