I have the latest AppList version, 1.5.15, which is the one that supports iOS 13. This is the call I make to get the icon:

[[ALApplicationList sharedApplicationList] iconOfSize:ALApplicationIconSizeSmall forDisplayIdentifier:identifier];

I call it in 2 locations, on device launch and inside a preference controller.

So it fails on iOS 13 when the device launches. Here is my launch.

I wait for a notification like this:

%ctor {
    //
    // I Both of these works on iOS 12
    //
    // CFNotificationCenterAddObserver(
    //     CFNotificationCenterGetDarwinNotifyCenter(), 
    //     NULL, 
    //     &initializeTweak, 
    //     CFSTR("SBSpringBoardDidLaunchNotification"), 
    //     NULL, 
    //     CFNotificationSuspensionBehaviorDeliverImmediately);

    CFNotificationCenterAddObserver(
        CFNotificationCenterGetLocalCenter(), 
        NULL, 
        (CFNotificationCallback)initializeTweak, 
        (CFStringRef)UIApplicationDidFinishLaunchingNotification, 
        NULL, 
        CFNotificationSuspensionBehaviorCoalesce
    );

And this is the `initializeTweak` method

static inline void initializeTweak(CFNotificationCenterRef center, void *observer, CFStringRef name, const void *object, CFDictionaryRef userInfo) {
    UIImage *i = [[ALApplicationList sharedApplicationList] iconOfSize:ALApplicationIconSizeSmall forDisplayIdentifier:@"com.apple.mobiletimer"];
}

And finally, here is the crash:

SpringBoard 21:02:28.368624  0700   -[SBClockApplicationIcon smallIcon]: unrecognized selector sent to instance 0x28397baa0
SpringBoard 21:02:28.817292  0700   *** Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: '-[SBClockApplicationIcon smallIcon]: unrecognized selector sent to instance 0x28397baa0'

Since that class was kinda specific to the clock, here's another one with a random app:

SpringBoard 21:05:04.134453  0700   -[SBApplicationIcon smallIcon]: unrecognized selector sent to instance 0x2819ddc70

So since the code actually works on iOS 13, I am guessing I would need to do this somewhere else? I would like to do it as soon as possible though.

Ideas?
