What is the difference in declaring a generic type in Swift?

Question

Swift

What is the difference between these two functions? I did not find an answer on the Internet.

Answer 1

In the form in which you gave them, the functions do not differ .
The parameter on the right specifies the type of T , in the tutorials this is called a type constraint .

static func max1<T:Comparable>(a: T, b: T) -> T {
     return a < b ? b : a
}
    
static func max2<T:Comparable>(a: T, b: T) -> T where T : Equatable {
     return a < b ? b : a
}
