Can i used same app group in apple watch and today extension?

i was used app group to share data with my apple watch and today extension from my app. the problem is i can able to get that app group data in today extension but i can't able to get this data in apple. so i just want to make sure that can i used the same app group to access it in today extension and even apple watch and which is the best way to same data with apple watch?

i used this to share data to app group

NSUserDefaults *sharedDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.myapp.data"];
[sharedDefaults setObject:[[NSUserDefaults standardUserDefaults]objectForKey:@"array1"] forKey:@"arrayVisibleCountryList"];
[sharedDefaults setObject:[[NSUserDefaults standardUserDefaults]objectForKey:@"array2"] forKey:@"arrayBaseCurrency"];
[sharedDefaults synchronize];


to retrive data from app group

NSUserDefaults *sharedDefaults = [[NSUserDefaults alloc] initWithSuiteName:@"group.com.myapp.data"];
NSMutableArray *array1=[[sharedDefaults objectForKey:@"array1"]mutableCopy];
NSMutableArray *array2=[[sharedDefaults objectForKey:@"array2"]mutableCopy];

Answer

This would have only worked in watchOS 1, when the watch extension ran on the phone, and could have accessed the phone's app group container.

In watchOS 2 or later, it's not possible to use an app group to share data between the phone and watch. You need to use Watch Connectivity to transfer data between the phone and the watch.
