Let's collect knowledge like we did with iOS 14, iOS 13, iOS 12, iOS 11, iOS 10, iOS 9, iOS 8 and iOS 7 – paste in your notes and share what you've learned, and somebody else will organize it later. :) If you want to ask questions and share tips over chat with other developers, see How to use IRC for how to connect to #theos and #iphonedev.

Hey developer, you can add your knowledge here! Yes, you! Make an account and edit this page!

New Signing Requirements

iOS 15.0+ requires DER encoding of the entitlements, as such it is required that all tweaks are signed with an updated ldid. iOS 15.1+ adds a requirement on hash agility, added in ldid version 2.1.5-procursus3 which can be found here.

SBHIconGridSizeClassSizes

SBHIconGridSizeClassSizes in all arguments of methods and functions is now passed via pointer, instead of being passed as a raw struct.

You can write code that supports both versions like so:

@interface SBIconListGridLayoutConfiguration : NSObject
-(void)setIconGridSizeClassSizes:(SBHIconGridSizeClassSizes)sizes;
@end

@interface i15SBIconListGridLayoutConfiguration : NSObject
-(void)setIconGridSizeClassSizes:(SBHIconGridSizeClassSizes *)sizes;
@end

...

SBHIconGridSizeClassSizes sizes = { .small = { .columns = (short)widgetWidth(2, loadoutValueColumns), .rows = 2 },
                                    .medium = { .columns = (short)widgetWidth(4, loadoutValueColumns), .rows = 2 },
                                    .large = { .columns = (short)widgetWidth(4, loadoutValueColumns), .rows = 6 },
                                    .extralarge = { .columns = (short)widgetWidth(4, loadoutValueColumns), .rows = 6 } };

if (@available(iOS 15, *))
    // Cast to the iOS 15 Interface so ARC allows us to compile this
    [(i15SBIconListGridLayoutConfiguration *)config setIconGridSizeClassSizes:&sizes];
else
    [config setIconGridSizeClassSizes:sizes];
