v2.10.2

Bugfixes

• The keychain item name used by Realm to manage the encryption keys for
  sync-related metadata is now set to a per-app name based on the bundle
  identifier. Keys that were previously stored within the single, shared Realm
  keychain item will be transparently migrated to the per-application keychain
  item.
• Fix downloading of the Realm core binaries when Xcode's command-line tools are
  set as the active developer directory for command-line interactions.
• Fix a crash that could occur when resolving a ThreadSafeReference to a List
  whose parent object had since been deleted.
