Good morning guys, I am developing an application in Swift, but I am new in the language and do not know some things, I would like to know how I attach the images from my gallery or open the mobile camera to take a photo.
Thanks in advance.

Whoa, whoa, whoa, whoa? follows the code to do that action, native to Ios, does not spend adding any lib.

You can make a giant code in your hand or use a pod, which is what I recommend. I’ve used the Alcameraviewcontroller pod, which makes it possible to take both photos and choose from the gallery. You can find his github here:
https://github.com/AlexLittlejohn/ALCameraViewController
Steps to use:
1) Add to your podfile:
pod 'ALCameraViewController'
2) Import into your file that will call the camera’s view controller the pod, with the following line:
import ALCameraViewController
3) When calling the camera’s view controller use the following code:
let cameraViewController = CameraViewController { [weak self] image, asset in
// A variável image que você recebe aqui vai ter a imagem que o usuário escolheu. Fique atento para o caso que ele cancela a escolha da imagem.
self?.dismiss(animated: true, completion: nil)
}
present(cameraViewController, animated: true, completion: nil)
