Recently, many developers complained that Apple threatened to remove their apps from the app store because their apps had not been updated for a long time. Now, Apple has sent a response, and those apps that have not been updated or cannot be downloaded for three years will be taken off the shelf < p > the notice Apple has sent to developers shows: "as part of the improvement of the app store, developers of apps that have not been updated in the past three years and have not reached the minimum download threshold will receive an email informing them that their apps may be deleted from the app store." < p > last week, developers such as Robert Kabwe and Emilia Lazer Walker reported that they had received these emails and said they had 90 days to update their apps or they would be deleted from the store < p > other developers also shared similar experiences on twitter, saying that Apple's policy and update time limit are unfair to independent developers < p > at the same time, they also expressed deeper concerns about Apple's decision to eliminate certain categories of applications. Lazer Walker believes that game applications may be affected < p > a developer said: "sometimes the software development process is completely over. I know the world expects eternal (free) growth, change and improvement, but sometimes the software is released and the story is over. The 'old' and 'stable' are not fault states. On the contrary, they symbolize success." < p > but as some developers have pointed out, Apple's explanation does clarify why it does not seem to implement these rules in a one size fits all manner. For example, a developer said that Pocket God, a popular game in the early stage of iPhone, has not been updated for seven years, but it still remains in the app store. This means that Apple believes it is still very popular < p > Apple said that deleting old apps is to ensure that "users maintain trust in high-quality applications" and improve discoverability, security, privacy and user experience. After all, if an application has problems due to obsolescence, more downloads will make a bad application a bigger problem. If there is an outdated application that few people download, who will be hurt < p > Apple also said that the company does not want the app store to be full of apps that developers and users forget, but to ensure that users can easily find better apps. It is easy to recognize Apple's practice that deleting old and seemingly unrelated apps is a good solution < p > in addition, apple post points out that from now on, anyone who receives notification will have 90 days to update their app instead of the original 30 days < p > although this should make it easier for developers to save their applications, as Lazer Walker said, it will not make applications "exist in the state of development completion". Apple seems to be interested only in products that have been completed but still attract attention. (small) < / P > < p >
