Updating iOs app with more features and minor design changing

Hey there, Thanks for checking out. So I will write everything I need here: I have an an iOs scanner app that also has OCR function(Xcode project). Here is what I need 1- SDKs and PODS are outdated, they need to be updated to latest version and errors that appear should be corrected. Also I want project to be updated to latest swift version. 2- App does not have save and history function inside, this may be added. (Still not sure about this one) 3- Menus and buttons should be changed and look more professional and fancy - I have example as attached 4- At photo screen when it is entered for the first time I want to show what buttons are for, when clicked hints will disappear and user will continue- I have example as attached. 5- First screen there is an image to test OCR function, when you click OCR it extracts image to text, I want to put a new image there, I can send you text to write in it. 6- At share screen at first there should be a pop up message telling user how to correctly save if export is OCR or just a scan. (Currently it is on the share screen also however I want to divide the warning message; when clicked on OK, save menu will pop up.) - I have example as attached 7- I will send you apps link after we talked.
