let imagepicker = UIImagePickerController()
imagepicker.delegate=self
imagepicker.sourceType=UIImagePickerControllerSourceType.photoLibrary
self.present(imagepicker ,animated: true, completion: nil)
}
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
if let Image1 = info[UIImagePickerControllerOriginalImage] as? UIImage {
myimage.image = Image1

func detect(){
let image2 = CIImage (Image1:myimage.image!)!

First issue: Looks like your delegate method declaration doesn't match the one in the protocol, so it's treated as a separate method. Xcode even gives a warning:
Instance method 'imagePickerController(picker:didFinishPickingMediaWithInfo:)' nearly matches optional requirement 'imagePickerController(_:didFinishPickingMediaWithInfo:)' of protocol 'UIImagePickerControllerDelegate'
Try changing this line:
func imagePickerController(picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : AnyObject]) {
to:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any])
UPD: please also read #dfd's comments below on how to avoid this (quite a common) type of confusion.
Second issue: as already mentioned by others, you should pass the parameter as the initialiser properly. With minimum changes to your code it will be:
let image2 = CIImage (image: myimage.image!)!
However, the less exclamation marks (i.e. force unwrapping) the better; for more info on that, check Optional Chaining as an Alternative to Forced Unwrapping.

Answer 2

This error because you have write error label
CIImage.init(image: <#T##UIImage#>)
you can do it like this
guard let image = myimage.image else {
return
}
let image2 = CIImage.init(image: image)

Answer 3

Your first problem is that you are missing the _ in your delegate call, just before picker: and you need to write Any instead of AnyObject. It should be:
func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [String : Any]) { //... }
Second problem, your function needs to be written like this:
let image2 = CIImage(image: myimage.image!)
