hi, you must understand i am here to finish your app but payment must be guaranteed too, i am here working for 9 years and not a scammer, so let's settle being fair for both parties, don't worry i work with swift and firebase day and day out. I am a Pro iOS & Android App developer here, I always strive to finish all my projects, also please check my latest reviews, portfolio on my profile page directly, Kind Regards, Iryna!
