ObjectBox Change Log

1.4.1 - 2020-11-10

• Several internal improvements under the hood; an indirect consequence is that Foundation is not implicitly imported anymore (you may have to add Foundation imports after upgrading)

• New sync annotation

• Build target for macOS set to 10.10 (was undefined before)

• Built with Swift 5.3

1.4.0 - 2020-09-08

• ToMany improvements

  • applyToDb() now puts new objects automatically; you do not have to put them individually an

  • New properties to probe the state: resolved and canInteractWithDb

  • A throwing resolveFromDb() to explicitly fetch the target objects allowing to catch errors before starting to interact with the target objects

  • getUncachedFromDb() and getUncachedIdsFromDb() for getting plain arrays from the database

  • Fixes: e.g. resolving now happens transactionally (improves performance too), removeAll() is now supported

• ToOne: putting an object with a ToOne, now avoids to put already persisted related ToOne target object. Note: While this is a fix, it may be a breaking change if you relied on that behavior before.

• Box: added a bulk get() for given IDs and renamed dictionaryWithEntities() to getAsDictionary()

• Read-only stores

• Added a version check to ensure that the library matches the generator

• Reduced framework size by omitting outdated 32 bit versions

1.3.1 - 2020-06-29

• Fixes for ToMany

• Several internal improvements, e.g. query links are resolved faster

1.3.0 - 2020-05-11

• Built with and for Swift 5.2

• Fix sporadic "errno 12" while opening a DB on iOS devices

• Lower deployment target to iOS 9.3 (seems to be still used by older iPads)

• Fix for PropertyQuery (e.g. single line construction without holding on to Query)

• API clean ups

  • Remove deprecated Query.all(); use find() instead

  • Box functions like visit(), for() and forEach() are now read-only by default. New optional writable flags changes this to use a write transaction instead.

1.2.0 - 2019-12-17

• Added support for optional unsigned property types

• Better type support for queries; e.g. unsigned and optional properties, Bool properties

• Property queries compute sums and averages more precisely (improved algorithms and wider types)

• Some Query API clean up, e.g. setting query parameters does not throw anymore, findUnique() always returns an optional result, etc.

1.1.1 - 2019-11-23

Fix for the 1.1 "realpath" error during build on machines without Homebrew coreutils.

1.1 - 2019-11-18

• Experimental Carthage support (in addition to CocoaPods)

• If a convert annotation on an enum has no explicit database type given, its RawType is used.

• Various performance optimizations

• Usability improvements, e.g.setup.rb now asks which project to use if there is more than one, and creates a non-empty *.generated.swift file to help with code completion.

• Added put() with variable argument list, put(inout) for mutable structs, and putAndReturnIDs(). Upgrade note: put() itself no longer returns IDs.

• Added variants of Box methods for ContiguousArray class, which are faster than the methods using standard arrays.

• Anonymous build statistics can be turned off using --no-statistics

1.0.1 - 2019-10-01

• Fix bug that prevented code generator from working in projects that use SwiftPM

1.0 - 2019-09-24

• Relations in queries

• Observer callbacks for data changes

• Many-to-many relations

• Asynchronous put/remove

• Edit relations through their backlinks

• API clean up; e.g. renames, simple IDs, simplifications, etc.

• If you've been using pre-releases, you can find migration instructions in the Readme on Github.

0.9.1 - 2019-08-13

iOS hotfix

• Fixed "Storage error code 78" for iOS

0.9.0 - 2019-07-22

Open Source Release

• Source code for the Swift binding is now available

• Reduced write/update time by about 25%

• Rewrote the remaining Objective-C classes in Swift

• Fix an issue reading an old entity written before a new, non-optional property was added to it

• Improvements for people using SwiftLint in their projects

• Added findIds(), visit()/forEach(). Added remove() for queries.

• Improved support for enums and other user-defined types

• Data and [UInt8] are now supported as property types.

• Binaries: Swift 5 ABI only

0.8.0 - 2019-05-14

Struct Support and Performance Improvements

• Immutable structs can now be used, you are no longer restricted to classes

• We no longer throw NSError-based errors, they're all enum ObjectBoxError cases now

• Strings that were created as NSStrings previously are now created as Swift Strings, which should reduce the number of unnecessary UTF-16/UTF-8 roundtrip conversions when Swift 5.1 arrives

• New projects are now set up with separate generated source files for each target by setup.rb.

• Binaries: Swift 5 ABI only

0.7.0 - 2019-04-02

Swift 5 and Build Improvements

• Binaries: Swift 5 ABI only

• ObjectBox setup script can now also be used without CocoaPods​

• ObjectBox can now be used in frameworks​

0.6.0 - 2018-12-19

Model Migration

• Your data model is now migrated transparently for you when you make changes

• Properties can be indexed​

• You can require property fields to be unique​

• You can specify a different name for use in the model than the instance variable's

• Use of ObjectBox without CocoaPods has been simplified

• You do not need to annotate back-links in relations anymore in clear cases

• Binaries: Swift 4 ABI only.

• Alpha users:

  • Use annotations // objectbox: instead of // sourcery:

  • Delete any database files you created before (one time only, starting with the beta we have model migrations)

0.5.5 - 2018-11-29

Alpha 6

• Remove code-generator limitations regarding order of properties vs. relations

• Support sandboxed macOS applications (see macOS Sandbox setup)
