Nit: we avoid declaring types for inline variables unless strictly needed. See the specific reference in our style guide at Type Inference | swift-guide (microsoft.github.io)

Based on the linked guide, it would still make sense to declare types in such cases. Here Int is not directly used as literal. It is the result of a function firstIndex on another type. So for quick understanding, I think it is helpful to have the type Int specified here.

The guide is consistent on this point:

Use type annotation as little as possible when declaring a constant or a variable; instead let the compiler infer the variable type.

Let the compiler infer the type of a constant or variable whenever possible.

The primary exception to this policy is for stored properties; local variables should almost never need a type declared, particularly when they are storing the result of a well-understood method like firstIndex.
