Did you try to loop through all indexes ?

let source = CGImageSourceCreateWithURL(inputURL as CFURL, nil)

if let source = source {

for index in 0..<cgimagesourcegetcount(source {

if let imageProperties = CGImageSourceCopyPropertiesAtIndex(source, index, nil) as? [String: Any] {

print("image properties \(String(describing: imageProperties))")

}

if let image = CGImageSourceCreateImageAtIndex(source, index, nil) {

print("image\(image)")

}
