core data - Using same iCloud enabled CoreData store across Watch Extension and iPhone -


i'm witnessing strange behaviour when opening icloud enabled coredata store apple watch extension. i'm using same icloud container across targets.

here picture shows folder (ubiquity container) structure looks inside ubiquity container :

different stores apple watch & iphone

it looks creates different stores iphone & watch

i'm sharing same coredata stack between iphone app & watch extension. ideas why happening ? if understand correctly treats iphone app & watch extension separate users ?

i appreciate if give advice.

you should use app groups share same core data store between watch , iphone. enable app groups both targets, configure in provisioning profiles , persistent store url this: 

nsurl *storeurl = [[nsfilemanager defaultmanager]       containerurlforsecurityapplicationgroupidentifier:appgroupidentifier];

the watch accessing core data store via watchkit extension enabled app groups. see e.g. figure 4.1 in apple's app extension programming guide.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
