Before iOS 5, the developer needed to manually manage the threads. However, the release of iOS 5 added new methods to the managed object context to eliminate the need for manual thread management; instead you can safely access Core Data objects through a block of code passed to the performBlock: or performBlockAndWait: methods.
Using a method that takes an NSError means using an optional variable (a variable that may or may not exist) and the unwrapping the error if it exists.
We don’t know the exact figures, but it’s obvious that only a very tiny number of them stand pasado because the Caudillo public becomes aware of only three or four new app names per year.
He's worked in teams of all sizes and has also led a few. Tommy takes a quality-focused approach to engineering and avoids taking shortcuts that compromise maintainability or user experience while always being aware of business needs.

But people usually make mistakes in finding and hiring the right iOS engineers. Let’s find out what some of those common mistakes are.
But without understanding multithreading, a developer cannot properly make use of Core Data or Realm since data persisting and consuming operations need careful management when being used in multiple threads at here the same time.
Keep in mind, though, that changes to Core Data objects do not necessarily propagate immediately to other threads. In the standard case, Core Data objects that are loaded into memory are not updated on a different thread until those objects are fetched again from persistent storage.
To sum up, if the app developer you are going to hire has full-stack knowledge, more info they will be able to write solid code.
