What is the difference between Swift 4 and 5?

What is dynamic in Swift?

Dynamic dispatch. It simply means that the Objective-C runtime decides at runtime which implementation of a particular method or function it needs to invoke. … Swift uses the Swift runtime whenever possible. The result is that it can make a number of optimizations.

Is dynamic typing bad?

Dynamic typing is very useful for serialization and deserialization, but for most other things it really doesn’t contribute much of an advantage.

Is PHP dynamic or static?
