Inferred to have type 'AnyClass', which may be unexpected

Question

Here is my code:

if let runningTests = NSClassFromString("XCTestCase") {
    return false
}

The compiler warning:

"Constant 'runningTests' inferred to have type 'AnyClass', which may be unexpected.

What is it I need to cast to to remove this warning without changing my code into a if != nil check on the result of NSClassFromString?

Answer 1

You actually mean AnyClass here, so you just need to tell the compiler that:

if let runningTests: AnyClass = NSClassFromString("XCTestCase") {
    return false
}
