Detach an Object from a Realm?

Question

Lets say I have the following scenario...

ViewController1 loads a Person object from a Realm on the main thread and passes it to ViewController2. User interaction in ViewController2 causes the same Person object to change, but I only want to persist the changes once the User has pressed "Save".

Currently, when changing the passed Person object in ViewController2 a runtime error is thrown saying changes to an object need to be made in a Write block. This makes sense, but in this scenario I don't actually want to persist the changes right away.

• Is there a way to detach an Object from a Realm to avoid these checks?
• If there isn't, what would be a suggested work around? (Copying the Object to a new instance? Tracking the changes to the Object separately and applying them later? Both seem pretty messy.)

Answer 1

Right now, you can make a 'standalone' copy of your object, via Object(value: existingObject) -- that'll probably be the simplest solution for now, until Realm adds something like nested transactions that will make undoing an arbitrary number of changes easier.
