Upgrade your existing app to iOS 11 if you want it to survive! If you app is 32-bit, say, made in 2014 or 2015, chances are, Apple will stop showing them in the App Store. The existing customer will be able to use them but there will no new downloads — and without downloads, there will be no more fresh money from the app. The solution is to let me upgrade, develop and maintain your old app. If your old developer is not available any more, or not interested, give me the source code of your app and access as…

The task is to publish four iOS apps to the store. Previously, the apps were properly compiled and code rectified for iOS 11. It took five weeks to come to the situation that the only task remaining is publishing the apps to the App Store.

Every year Apple releases a new version iOS and if you have apps in the App Store, you need to upgrade them. In several previous versions, the penalty for not upgrading the apps to the latest version of iOS was not severe. There used to be many apps published in, say, 2014, and still running happily on iPhones and iPad. However, this year, 2017, Apple will punish you if you do not upgrade your apps to the 64 version — your app will not be seen in the Store any more. The apps will continue to function for the existing…

This is the best video I have found on YouTube on how to publish the app to the App Store. Specifically, it is about getting provisional certificates in order to test your app with UDID numbers already contained in the app. You may also want to follow the official Apple documentation, here: https://developer.apple.com/library/content/documentation/IDEs/Conceptual/AppDistributionGuide/Introduction/Introduction.html#//apple_ref/doc/uid/TP40012582-CH1-SW1

Here is how to use the current version of the Location Map plugin. As it stands, this combination works. You will be able to enter new points, connect already existing screens to them, zoom at will, tap to go to the screen from a related pin, and so on. There is only one catch: you have to enter the screen name through the Load Screen With Nickname field after clicking on the name of the element in the Location Title column. You will notice that the Item Properties screen now contains fields Callout Window Tap Action and Load Screen With…
