Hi Teutz,
Along with the upgrade to iOS 12, it will also need to xCode upgrade to xCode 10.
Upgrading from will not be a long work as the code is already developed for iPhone X and iPad.
About Us and experience with iOS:
- Used Xcode to develop apps for iOS, iPad, watchOS, and tvOS
- Working on the latest version 10.1.
- Used Xcode with the programming languages C, C++, Objective-C, Objective-C++, Java, AppleScript, Python, Ruby, ResEdit (Rez), and Swift, with a variety of programming models, including but not limited to Cocoa, Carbon, and Java.
- Third parties have added support for GNU Pascal, Ada, C#, Perl, D and Fortran
- On server side used AWS, Azure, digital ocean, GCP and more.
- MVC / MVP / VIPER / MVVM + RxSwift
We are a seasoned development team with 8 years of experience. The senior developer name SHIVAM will directly work with you and he's the best with iOS (Swift)
After checking the code, we will tell you the exact time in days or hours to complete but without checking the code, can't really give final time.
IMPORTANT:
Code warranty for 12 months. Also, your app will not face 1-sec downtime or any trouble. We request to see details over CHAT so that give you a firm timeline.
Thank you!
Sufiyan Rao.
