Day 4/100 day of SwiftUI

Mission log 4.

Type Annotation

Type annotation let us state what data type we want for our variable and constant.

example:

var name: String = "Opeyemi"

Type inference is when swift is able to figure out the data type of a variable or constants, based on value we assign.

example:

var name = "John Doe"

From the snippet above , swift will infer the data type to be String, because we assign text value to the variable.
