Welcome My name is Dr. Nicholas Outram, I’m an Associate Professor (Senior Lecturer) in Computing and Electronics in the School of Computing, Electronics and Mathematics (SoCEM), Plymouth University (UK). One of my interests is in teaching iOS Development to learners iOS…
JSON encoding in Swift is now super convenient since the introduction of the Codable protocol. When working with web services, or teaching materials for students for that matter, it’s most helpful to have JSON formatted in a human readable form. It…
There has been some discussion about the recent decision by Apple to move iTunes U collections to the Apple Podcasts platform. These still seem to be accessible from the iTunes desktop application, even on the Windows platform. It is arguably…

My iOS development (weblog.outram.org) blog has now moved here http://blogs.plymouth.ac.uk/iosdevelopment
All new content on iOS will only appear on this university site.
This is designed in part to complement the iTunes U course iTunes.com/plymouthswift
iOS Apps are typically built from controllers, each with an associated view hierarchy (typically filling a screen). These together are often called a scene. As the user navigates from scene to scene, so the data needs to flow from one controller to the other. If…
If you want to present one view controller from another, and use the popover modal style, you would typically set the modalPresentationStyle of the controller to .popover before you present it.
