Because of the each bit in n part; 11 is not represented as 1011 for each bit in n, but rather as 0..0001011 (depending on size of int).

The description states:

if the bit is 1, swap the case; if its 0, leave it as is.

And:

When you finish with the last bit of n, start again with the first bit.

What is inconsistent here?

Very interesting kata.

Good kata, but there is a problem with Swift unit tests and example

func swap(_ s: String, n: Int) -> String { // _ is missed before n

XCTAssertEqual(swap("the quick broWn fox leapt over the fence", 9),
"The QUicK BrowN foX LeaPT ovER thE FenCE")

Description is inconsistent. Each bit in n will specify whether or not to swap the case versus because 11 is 1011 in binary, so the 1st, 3rd, 4th, 5th, 7th, 8th and 9th alphabetical characters have to be swapped. You really need to describe this more carefully.

You need to replace "func swap(_ s: String, n: Int) -> String" with "func swap(_ s: String, _ n: Int) -> String". Then the error "type of expression is ambiguous without more context" will disappear

Thanks :)
