BUILD SNAPCHAT CAMERA IN iOS WITH SWIFT - AVKIT AND AVFOUNDATION

DOWNLOAD RESOURCES: https://ductran.co/p/38 In iOS and Swift, in order to show up a camera and take a photo or record a video, we can use the default UIImagePickerController. But sometimes, you want to create something minimalistic, simpler with custom design. So let's do that in this training. You'll learn: How to use AVKit and AVFoundation Configure AVCaptureSession and AVCaptureDevice to take photos Add UITapGestureRecognizer to switch from front facing camera to back facing camera Save the taken photo to photos library Let's get started by downloading all the resources I prepared for you in this episode below!
