I added "NSKeyedUnarchiveFromData" to value transformer name of the core data entity, it should be the default, but you never know. This nanoparticle consists of a tumor acidity-activated TAT [the TAT lysine residues’ amines was modified with 2,3-dimethylmaleic anhydride (DA)], a flexible chain polyphosphoester core coencapsulated a NIR dye IR-780, and DOX (doxorubicin). This is an abridged chapter from our book Core Data by Tutorials, which has been completely updated for Swift 4.2 and iOS 12. EDIT 3: Just out of curiosity I filled out all the fields for the transformable attribute (it was never required before). Core Data will wait until you access a property to fully materialize this object in memory. For floating point numbers, I would recommend to only use doubles, because they're used almost everywhere for calculations. For that you can use primitive properties which other backing store of Core Data. Es wurde für ASP.NET Core 5.0 aktualisiert. This tutorial is presented as part of our iOS 12 Launch Party — enjoy!
