We will be learning how we can use ‘some’ and ‘any’ in Swift.
‘some’ keyword was introduced in 5.1 however, the ‘any’ keyword was introduced in Swift 5.6
In Swift 5.7 we can use these two keywords in the function’s parameter position.
So let’s discuss in detail regarding these keywords.
Here is an example code snippet of how we can use the ‘some’ and ‘any’ keywords with functions.
Above all, let’s define a protocol as mentioned in the above code snippet.
Now we will define the struct that uses the AnyProtocolName protocol as below.
Please be noted that the data types of the anyStructOne and anyStructTwo are different, which are anyStructThree & anyStructFour
We can use the ‘some’ keyword in the function’s parameter position which is the same as making the function generic. However, it is used together with a protocol to create an opaque type that represents something that is conformed to a specific protocol.
In addition, ‘some’ keyword can be used with variables as described below.
Here, we are telling the compiler that we are working on a specific concrete type.
So it will throw a compile time error when we change the type.
In Swift 5.6, the ‘any’ keyword is not mandatory when creating an existential type, but in Swift 5.7, you will get a compile error.
Here is an example of how we can use the ‘any’ keyword.
Unlike the ‘some’ keyword we can use ‘any’ keyword for protocols with associated types.
