Add edit function and fix existing notification

General information for the app: send messages
Kind of development: Customization of existing app
Description of requirements/features:

Hi guys,

My IOS app is almost finished with only 10% work left. I have an existing IOS app built using swift using back4app as backend (parse)

At the moment in the app I can add messages however I want the option to

1) edit personal message and then update

2) I had an existing feature built by another freelancer where you can take a picture and send to friend however notification doesn't work for that feature.

Notification works for everything else within the app such as message, sending pic from library however doesn't work for when picture is taken and sent.

I have a functional specification, if interested please let me know and we can have a chat over Skype and then confirm on pph.
