I have written a small Cocoa program that works in High Sierra but stopped working in Mojave. The program loads a graphics file from disk and displays it full screen. At the bottom it should write the

A friend of mine has a problem: When he installs an app (via Xcode) on his iPhone it works fine (probably the app will expire after one year). But when he installs the same app on his iPad, the app wi

During development of a new version of my app, I added a new data model version with one additional attribute on one of the entities, and a mapping model to set the default value of that new required

Doc and window restoration is great when relaunching the app, but I also want each document's window to open to their last frame when the user opens documents. I can not find the right place to make t

In my Core Data model, I've added a 2nd version with a new attribute. This attribute needs to be initialized to a sequential value upon migration from the old version. So I'm using a mapping model and

I'm putting up a sheet from a nib to display progress while I process things. When processing is done, I change the button name and ensure the progress bar is set to max. At that point, one of the lab

Does anyone know when NSTimeZone changes on iOS when the GPS location of the device changes? I have tested on my device and Simulator and it appears when running in the Simulator, that NSTimeZone.loca
