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.

Developing tweaks for the palera1n tethered iOS 15.x JB
This jailbreak is primarily a developer jailbreak and has certain restrictions.
Procursus: 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
This class is responsible for icon grid constraints.
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
// I need to double-check whether this actually needs to be allocated or whether passing it a stack pointer works fine.
[(i15SBIconListGridLayoutConfiguration *)config setIconGridSizeClassSizes:&sizes];
else
[config setIconGridSizeClassSizes:sizes];
