Xcode allow user to input image

How would you go about allowing the user to input an image in an Xcode app on iPhone?
For example setting a profile picture, where the actual user chooses the image from their photo library (or take picture etc.)
To pick a photo, you'll need a PHPickerViewController.
This documentation page should help to understand how to use it: Selecting Photos and Videos in iOS.
The easiest way to take a picture is to present a UIImagePickerController with the sourceType of .camera.

How to use gallery on apps that only allow to get a picture from a camera app?

Is there a way to upload images through gallery on apps that only allows the images to be taken by camera?
I know there are apps like fakecamera which allows the same but a recent update to the app in which I upload images through gallery using FakeCamera has disabled this functionality. Every time I click on camera button in the app only my mobile camera is opened (earlier whenever I clicked the camera button, a selection dialog used to came to select between fake camera or camera to upload image). But now only my default camera is opened every time. If this needs to Mod the apk, I am ready to do that but please someone help me out with this, I am so frustrated.....

iOS Loss of image quality and resolution

I have and imageview that i use throughout my app. It can hold a picture from the gallery or from the camera.
In the end I upload it to a webserver using php.
But where does xcode downscale my image? Ipad pictures are aprox. 300x300px.
Tried downloading a 1000+ x 1000+ pixels image, but it looks like it gets downscaled once i open it trough uiimagepicker. In my gallery its fine before i start my app, but when i add it via my gallery its low res.
I need these images with the resolution they were made with.
Is there any way to obtatain that?
