Apple is always trying to motivate everyone to use its newest smartphones, tablets, computers and even more software. If the owner of the iPhone has been updated to a newer version of iOS, then install an older, he will never be able, since the "apple" corporation does not allow it to do. Exactly the same approach she uses coercion and to all developers, which recently obliged to adapt all their applications and games for the iPhone screen X.
9to5Mac writes edition, that the authors of the software for iOS received an email from Apple, which states that, that absolutely all the new programs and games 1 April 2018 year must have the support of iPhone X smartphone, that is, they must be fully compatible with its screen, Scanner Face Face ID and other features.
While that innovations affect only new applications, that is, if some developer wants to create and lay out in the App Store some game or program, it must necessarily be fully compatible with the iPhone X. This has a positive impact on the owners of the new flagship Apple, because they will get compatible software, but the developers it greatly complicates life, because now each of them will have to create applications with a view to an elongated screen smartphone best "apple" of the corporation.
Also, all new programs, added to the App Store from April 2018 of the year, must necessarily be developed for the iOS operating system 11, that is, using its proprietary special SDK. This is to ensure, developers had to apply the most advanced technologies and solutions, aimed at improving the performance and implementation of new features.
When Apple will start to remove the program from the App Store, which are not optimized for the iPhone screen X, yet unknown, but it will not happen before exactly 2019 of the year.
