ios - creation of realm file in App-Group Folder does not work under WatchOS (WatchKit Extension) -


the following code works under ios-8.x / swift-1.2 / watchkit-1.0

    // create realm_db-file in shared app-groups folder     let directory: nsurl = nsfilemanager.defaultmanager().containerurlforsecurityapplicationgroupidentifier(appconstants.app_group_identifier_key)!     let realmpath = directory.path!.stringbyappendingpathcomponent(appconstants.realm_filename_key)     playerrealm = realm.init(path: realmpath)

but doesn't work under ios-9.0.1 / swift-2.0 / watchos-2.0

the 2 error messages are:

1.) 'stringbyappendingpatchcomponent' unavailable: use urlbyappendingpathcomponent on nsurl instead

2.) call can throw, not marked 'try' , error not handled

enter image description here

any appreciated !

to fix first issue, need cast:

directory.path nsstring

since path returning string, in swift doesn't offer stringbyappendingpathcomponent method.

second, swift 2.0 has new error handling, methods can throw error labeled throws. these methods require add try before call. see apple's docs on this: swift error handling

to disable error handling if know path guaranteed work can simple write:

playerrealm = try! realm(path: realmpath)
