picker.delegate = self <– what does this do for us ?? It's a question puzzling me for a long time. Appreciate anyone help on this

How do we make the photo we take to save in camera roll?

Excellent tutorial. Very easy and well explained. Thanks!

That’s two great iOS tutorials I’ve read here in a row. Thanks Rafael. Strangely enough, I got the same problem as Senthamil when I went through the article but the problem disappeared when I downloaded the source code and cut and pasted from there.

Hi – thank you for this. Is it possible to take a photo using a resized window version? So instead of the viewfinder being the full screen, I would like to resize the view finder to something smaller?

After i take that photo I want to allow the user to be able to rotate it or resize it before clicking on use photo how can I do that?

Hi great work, excellent tutorial. Can you help me with this problem? My problem is that I already have an Image selected but i want to edit it. If you see the contacts app of ios when you save a contact with an image and then if you want to edit the already selected image it directly show the Move and Scale Screen. How can I achieve this. That is show the Move and Scale screen directly without opening the camera or the photo library.

If there is no memory left in the device, will Apple’s API allow the camera to even open?

I’ve got a million dollar idea. I need a developer. No bullshiting. It is the next big thing. I need developers to work with.

Fantastic guide, helped a lot, Thank you so much.
Appreciate if you could add some updates regarding iOS 11 SDK, the app may crash if we do not add it.
Kindly add the following to info.plist:

NSCameraUsageDescription
