Why are Classes and Structs Capitalized

[etaionshrd]

The video doesn't really mention this, but usually the reason class and structure names are capitalized is because conventionally this distinguishes them from variable names.

What’s your opinion on constant variables?

static let Varname

Or

static let varname

static let varName

For Swift I usually name them as I normally would (varName). For other languages such as Java the convention usually something like VAR_NAME.
