With a special focus on migrating your app from iOS7 to iOS8, I'll be providing you details about proceeding ahead with the same in a simple manner.

And now, the three simple-to-follow steps for migrating your app from iOS7 to iOS8

Step 1- Download the latest Xcode version from Apple's iOS Dev Center

Currently, Xcode 6 GM is the Xcode version that's available for the iOS App developers. With the release of iOS8, Apple will also be releasing the final Xcode6 version.

Step 2- Get an iOS8 compatible device to test the application

Since a majority of iOS versions aren't compatible with all Apple devices,it is recommended to test your device to check whether the app's features work flawlessly. Some of the best examples of devices that can aid you in testing your app include an iPhone 4s, iPhone 5, iPhone 5c, iPhone 5s, iPad 2, iPad 3rd generation, iPad 4th generation, iPad Air and an iPad mini.

Making changes to your app at this time would make you face many warning messages with most of them related to the deprecated properties or methods. Thus, in order to check which of the APIs and frameworks used in the app have changed from iOS 7.1 to iOS 8, it is mandatory to have a glimpse of the iOS 8.0 API Diffs page.
