This is my first app.
I want to create this for a friends company, he owns a carpentry company and he asked me if this is possible, I'm 100% it can be done and so I'm having a shot at it. Basically i want to be able to take a picture of a wall then select from a list of shelfs preset in the app and stretch the image of the shelf to the requires size (possibly add more shelfs if required) then saved the image of the shelves on the wall and email it to my friends business email, i want the user to be able to add some text and stuff to the email though.
Ill post my code first and then ill explain the problem

I AM using Storyboards, basically what i want to do is after my UIImagepicker has run and then a picture has been selected i want if possible to load the "secondViewController" and then display the image selected in that view controller, on the storyboard on my second VC i have got an ImageView and a toolbar at the moment I'm not using the toolbar, i have tried various different codes but none have worked yet so i have stripped it back to the bare basics so that anyone that actually knows what i need to do doesn't need to tell me what to delete, i know its not mandatory but i think id like to do this with a segue.
I've been working on this for a few days now n its really grinding on me, but i know it takes time and i would really appreciate your help :) thank you in advance
EDIT: have a new problem, now the the secondviewcontroller loads, i cannot display the selected image in the uiimageview on the secondviewcontroller
