Data Binding Working in Angular JS

Data Binding Angular JS

Data binding refers to the process that is used for establishing a connection between the application UI and business logic. The Two-way data binding point towards the ability of binding changes with an object’s properties to changes in the UI and vice-versa. It means if we have a user object with a name property, when we assign a new value to user.name the UI will display the new name. Similarly, if an input field is included in UI for the username then the entering of value will result in a change in the name property of the user object.

Using Swift to Call Objective C Code

Swift is a new programming language that is purely compatible with objective C. This makes it possible to use objective C file code in Swift file. Apple claims the co-existence of Swift and Objective C in an application but, this does not relate to re-using old classes made  in Objective-C whilst building new classes in Swift. The reason being as Objective-C is a platform-independent language unlike  Swift is platform-dependent.
