Hi there-I'm an iOS developer, It is one day process so I need your developer account, Code, but I've come across with many clients after they spent with thousands of dollars, later project will be dropped on 60% or 70 or 80 or even in 90% by previous developers and then they again need to spend another few $Ks to complete 10% or maximum 40% of the remaining work. But ask in order to choose a good one just this ask this question:) why Xcode adds "!" in "@IBOutlet weak var someLabel: UILabel!’ when you create a connection between Storyboard and Controller file for an outlet? it will require 2 pages of explanation, if that they are one line responder then think about it..
this does not mean they could not make this certification part but getting the proper understating will be needed for anything
so If I am recruited all I need a time and support to give you a better output for your portfolio : Thanks
