Answer 1

UPDATE: This method does not work on iOS 12 - entitlement required

There is a way to find if a specific application is installed, its not a list of all apps like allInstalledApplications returned but its useful to query for a specific bundle id

Here is an example, the method receives bundle id and return true if it's installed on the device:

- (BOOL)checkIfAppInstalled: (NSString*)bundleID {
    dlopen("/System/Library/PrivateFrameworks/MobileContainerManager.framework/MobileContainerManager",RTLD_NOW);
    Class MBAppManager = NSClassFromString(@"MCMAppDataContainer");
    NSError  * error ;
    id contentApp = [MBAppManager performSelector:@selector(containerWithIdentifier:error:) withObject:bundleID withObject:error];
    return contentApp != nil;
}
