Let's collect knowledge like we did with 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.

What has changed in iOS 13? (Classes, frameworks, etc.)

Generating an apps icon image

Previously an icon image could be generated from an icon object like so

SBIcon *icon = someIcon;
UIImage *iconImage = [icon generateIconImage:2];

In iOS 13 this method was changed to -generateIconImageWithInfo:(struct SBIconImageInfo)info

struct SBIconImageInfo {
    CGSize size;
    CGFloat scale;
    CGFloat continuousCornerRadius;
};

SBIconController *iconController = [NSClassFromString(@"SBIconController") sharedInstance];
SBIcon *icon = [iconController.model expectedIconForDisplayIdentifier:@"com.apple.Music"];

CGSize imageSize = CGSizeMake(60, 60);

struct SBIconImageInfo imageInfo;
imageInfo.size  = imageSize;
imageInfo.scale = [UIScreen mainScreen].scale;
imageInfo.continuousCornerRadius = 12;

UIImage *iconImage = [icon generateIconImageWithInfo:imageInfo];
