Is this response from the compiler valid?

Question

The following code invokes an error. I could not find any information on this is in the reference. The lack of whitespace on the right hand side of the \'=\' operator is an

Answer 1

Add a space after the =. (=[ looks too sad to be an operator.) It's probably seeing =value as a use of a (possible, but not implemented) prefix operator.

Swift isn't entirely whitespace-agnostic like C... in particular, it uses whitespace to distinguish prefix from postfix operators (because ++i++ in C is a grammar oddity). But it's not ridiculously strict about whitespace like Python either.

Answer 2

Place a space between = and [,

let names = ["Anna", "Alex", "Brian", "Jack"]

It seems that =[ is a reserved operator.

Answer 3

Try adding a space between the = and [.

When the equals sign is directly in front of the bracket, the compiler assumes that you are trying to perfom a prefix operation on the array.
