SwiftUI training course for iOS App Developers

Who should attend

iOS developers who are looking to benefit from the latest User Interface development enhancements of SwiftUI.

Prerequisites

Live, instructor-led online and on-site training

We appreciate that you need flexibility to fit in with new working situations - whether you're an individual, part of a distributed team, or simply have projects and deadlines to meet. 

Our remote training can take place online in a virtual classroom, with content split into modules to accommodate your scheduling challenges and meet your learning goals. Get in touch today to find out how we can help design a cost-effective, flexible training solution.

Session 9: Final case study

• Students will be given a case study app to build - a conference programme app with multiple screens and interaction. It is based on the iOSDevUK conference app that we build each year - delegates will be provided with a ViewModel, model and data for this year's conference, and screens for what the app might look like. However, they will be free to explore other ways of presenting the data.
• Alternatively, where delegates have other specific challenges that they wish to explore, they will be supported in finding out how their challenges can be met using SwiftUI.
