Issue Description:

Placing @avilable(iOS, obsoleted) above a function is not preventing the execution of that function on newer platforms.

Example:

override func viewDidLoad() {
     super.viewDidLoad()        
     testFunc()
}
    
@available(iOS, obsoleted: 10.0)
func testFunc() {
     print("testFunc")
}
@available(iOS, obsoleted: 10.0)
    override func invalidationContext(forPreferredLayoutAttributes preferredAttributes: UICollectionViewLayoutAttributes, withOriginalAttributes originalAttributes: UICollectionViewLayoutAttributes) -> UICollectionViewLayoutInvalidationContext

Yeah, we don't have availability checking for "max allowed OS" implemented yet.

I wonder when this option will be applied in Swift.

I believe this is implemented. The following fails to type check for a deployment target > macOS 11 with the Swift 5.6 compiler:

@available(macOS, obsoleted: 11.0)
func test() {} // note: 'test()' was obsoleted in macOS 11.0

test() // error: 'test()' is unavailable in macOS
