# Changes in this fork

## Compiling

* Updated to Swift 5
* Updated for compatibility with iOS 13

## Cropping

* Image cropping now uses a rectangle with a specified aspect ratio rather than a square.  
* Added a center point circle in the middle of the crop rectangle that shows a touch point for moving the crop overlay. Previously, the user could move the crop overlay by dragging anywhere in the crop bounds, but this prevents pinch-resizing of the image except at the very edge. The resize corners still work as before.

## Camera

* Cleaned up the constraints for the flash, swap, and library buttons to work properly in both landscape orientations
* Update the overlay constraints when rotating, so the overlay is properly positioned and sized
* If the camera is not available (ie. on simulator), pop up an error rather than crashing
* Hide flash button if the flash is not available (for instance, iPads)

## Library Picker

* Adding a pinch gesture to increase or decrease the number of columns shown, up to a min or max value


## Confirm / Cropping View

* Significant updates to the presentation of the image, scrolling, and cropping to fix inconsistencies especially when switching between portrait and landscape.  See source file for full details.
* Allow zooming in on the image during cropping
* Rotate button to rotate the image 90 degrees clockwise on each press

## Example 

* Added a tap gesture on the displayed image to allow re-cropping the image (illustrates bringing up the crop view directly)
* The example was updated to show a crop aspect ratio of 1.2
