Why Downgrade?

There are several reasons why an iOS developer might want to downgrade their device from the latest version of iOS, 18, to the previous one, iOS 17:

• Compatibility Issues: If you are developing for an older version of iOS, downgrading may be necessary to ensure that your app is compatible with the target platform.

• Testing: Downgrading can also help you test your app on a specific version of iOS. This can be useful when trying to identify and fix compatibility issues or bugs that only occur on certain versions of the operating system.

After researching the issue, they discovered that there were some known performance issues with iOS 15 that could be resolved by downgrading to iOS 14.

20. The developer followed the steps outlined in Method 2 above and successfully downgraded their device from iOS 15 to iOS 14.

Conclusion

Downgrading from the latest version of iOS, 18, to the previous one, iOS 17, can be a useful tool for developers who want to resolve stability issues or test their app on a specific version of iOS.
