[FIXED] How to select a portion of an image, crop, and save it using Swift?

Issue

I am trying to create an iOS app using Swift to capture images and let the user save a selected portion of the image. In many cam based apps, I noticed that a rectangular frame is offered to let the users choose the desired portion. This involves either sliding the edges of the rectangle or moving the corners to fit the required area.

Could you please guide me on how to implement that moveable rectangle and how to save only that piece of the image?

Solution

Found one more solution. This time it is in Swift. The solution looks elegant and the code relative to other such solutions is written in fewer number of lines.

Here it is.. https://github.com/DuncanMC/CropImg Thanks to Duncan Champney for making his work available on github.
