The Swift Package Manager is a tool for automating the distribution of Swift code and is integrated into the
swiftcompiler. Once you have your Swift package set up, adding InputBarAccessoryView as a dependency is as easy as adding it to the dependencies value of your Package.swift.
dependencies: [ .package(url: "https://github.com/nathantannar4/InputBarAccessoryView.git", .upToNextMajor(from: "5.2.0")) ]
You can also add it via XCode SPM editor with URL:

The layout of the
InputBarAccessoryViewis made of of 4
InputStackView's and an
InputTextView. The padding of the subviews can be easily adjusted by changing the
textViewPaddingproperties. The constraints will automatically be updated.
It is important to note that each of the
InputStackView's to the left and right of the
InputTextVieware anchored by a width constraint. This way the
InputTextViewwill always fill the space inbetween in addition to providing methods that can easily be called to hide all buttons to the right or left of the
InputTextViewby setting the width constraint constant to 0. The bottom and top stack views are not height constraint and rely on their
func setLeftStackViewWidthConstant(to newValue: CGFloat, animated: Bool)
func setRightStackViewWidthConstant(to newValue: CGFloat, animated: Bool)
InputBarButtonItemhas properties that can hold actions that will be executed during various hooks such as the button being touched, the
UITextViewtext changing and more! Thanks to these easy hooks with a few lines of code the items can be easily resized and animated similar to that of the Facebook messenger app.
