We have an iPhone app where we are extensively using NSPredicate for array filtering. With iOS 15.1 upgrade, we started seeing performance issues with our app. After troubleshooting, we found slowness with array filtering, which otherwise works pretty fast on iOS 15.0.2 and below versions.
Has anyone else faced such issue? If so, any resolution available? We couldn't find anything in release notes for iOS 15.1, which could cause this issue.
Update - Added sample code
NSPredicate *predicate = [NSPredicate predicateWithFormat:@“ID = %@“, value]; NSMutableArray *result = [data filteredArrayUsingPredicate:predicate];
Here, data is of type NSArray.
