Is there anyone who can sync iOS coredata with an external library

Question

I have tried many libraries and frameworks. But I could not find one that works 100%. Can this be done using these external libraries and frameworks?

I tried all of these libraries for several days, so I might have missed something. And my project is quite complicated.

Here is the list of libraries that I used.

• iCloud: everyone knows this will not work. crash / incorrect data after synchronization
• Parsing with FTASync ( https://github.com/itsniper/FTASync ): it will work many times. I can not check the functionality.
• Simperium: ( https://simperium.com/ ) I work when I change several data, but it does not synchronize while changing many data at the same time.
• WasabiSync: ( http://wasabisync.com/ ) I cannot get it to work with my project.
• TICoreDataSync: ( https://github.com/nothirst/TICoreDataSync ) I tried it with Dropbox. sometimes it cannot sync small data. Sometimes it duplicates data from one device to another.
• UbiquityStoreManager: ( https://github.com/lhunath/UbiquityStoreManager ) This will lose some data during synchronization. sometimes it duplicates my data.
• FireData: ( https://www.firebase.com/ ) This synchronization is performed at maximum speed, almost instantly. But sometimes it crashes, sometimes losing data.

I really want to know that if someone can use some of these libraries in production with complex data. If someone does this, it means that I can configure it incorrectly.

If anyone has a suggestion, it would be great. Thanks

There is no special synchronization tool that works well. This is a difficult problem to solve; nobody has ever done it.

You must write your own, from scratch, specially designed for your own data structure.
