Float doesn't have any real advantages over Double. In fact Double is more precise, Swift uses Double as a default and as best practice you should too.

A little information about Float vs Double in swift:

  • Double represents a 64-bit floating-point number.

  • Float represents a 32-bit floating-point number.

If you work with a lot of floating-point numbers (like thousands or more) and accuracy is not a problem then you can use float, otherwise just use Double.
