PSPDFKit now requires and is built with Xcode 11.3 (11C29).

See the announcement post and migration guide for this release.

API

Changes the localized string key Redact to be for the redaction annotation type instead of the word “Redact”, which is no longer translated by PSPDFKit. In other words, the key Redact was removed and then the key Redaction was changed to Redact to match the PDF specification. The best way to get this localized string key is to use the constant PSPDFAnnotationStringRedaction. (#21243)
API

Changes the localized string key for the file annotation type from File to FileAttachment to match the PDF specification. The best way to get this localized string key is to use the constant PSPDFAnnotationStringFile. (#21243)

Changed

Improves font selection and prefers fonts already in the document in more cases. (#22530)
Removed

Removes the localized strings entry with the key Squiggle, which was not used. The localized text for the squiggly annotation type has changed to ‘Squiggle’ using the key Squiggly as before. The best way to get this localized string key is to use the constant PSPDFAnnotationStringSquiggly. (#22861)
Changed

Uses modern NSFontDescriptor enums on macOS for better Swift bindings. (#22678)
Fixed

Fixes a problem where encrypted documents could not be digitally signed correctly. (#22722)

The form elements can still be addressed individually by appending .x to the (fully qualified) name of the form field, where x is the index of the form element in the annotations property of the PSPDFFormField. (#22755)
Fixed

Fixes an issue where popup annotations were positioned incorrectly. (#22730)

3.1.0 - 6 Dec 2018

API

The distinction between standard stamps and custom text stamps has been clarified with the following deprecations and replacements. If you previously used the stamp subject consider whether you want a standard or custom text stamp. For standard stamps, subject has been deprecated in favor of stampType and the value of this property should usually be one of the values defined by the new PSPDFStampType string enum. PSPDFKit will provide the localized title for standard stamps. localizedSubject has been deprecated in favor of title. Set the title instead of stampType for custom text stamps, where you provide a title that has already been localized or user-generated. subtext has been deprecated in favor of subtitle. (#15895)

2.6.0 - 31 May 2018

This version of PSPDFKit requires and is built with Xcode 9.4 (9F1027a). The new Image Documents component, which enables you to keep PSPDFImageDocuments editable even after saving, requires an updated license.

We prepared a migration guide to help you with some of the API changes in this version.

API

The configuration builder blocks in PSPDFBaseConfiguration are now noescape for better Swift compatibility. (#15077)
API

The constants in PSPDFAnnotationStyleManager have been renamed and now better map to Swift. (#15077)

Removed

Deprecates class-level methods on PSPDFProcessor and introduces new new instance-based API that allows for cancellation. (#10480)
Added

Adds the ability to keep annotations on PSPDFImageDocuments editable even after saving. Requires the Image Documents feature to be enabled in your license. See /blog/image-documents/ for more information. (#14894)
Added

Adds an external file source option when adding new pages to a document with the document editor. (V##248)
Added

Adds blend modes to Annotations. This improves rendering for appearance steams with different blend modes. (#15080)
Added

Adds the ability to define arbitrary patterns for new pages when editing a document. (#14951)
Added

Adds the ability to embed files to PSPDFFileAnnotation using -[PSPDFEmbeddedFile initWithFileURL:fileDescription:]. (#15210)
Changed

Improves JavaScript support, including form formatting, calculation, and validation. (#9501)
Changed

Improves XFDF output by omiting opacity if set to the default (1.0). (#15354)
Changed

Improves rendering behavior for stamp annotations. Stamps are keeping their aspect ratio on resizing now. Stamps created with PSPDFKit now always use the same rendering, no matter if they were just created or after being saved in the document. The subject of stamps is now always rendered in uppercase characters. Custom stamps are now sized-to-fit before adding them to the document. (#1824)
Added

Added annotation name to Instant JSON. Also renamed pspdfkit/file name to filename to prevent collisions. (#14856)
Added

Added better detection for standard stamp subjects for Instant JSON. (#14919)
Changed

Cancelling a PSPDFRenderTask now reduces further CPU usage more effectively. (#14218)
Changed

PSPDFPageRenderer is now deprecated and will be removed in a later update. (#15189)
Fixed

Fixes a crash which occurred when manually searching a protected document. (#15177)
Fixed

Fixes a potential deadlock situation during document cache invalidation. (#15259)
Fixed

Fixes an issue where glyph frames were larger than expected due to unexpected values in their fonts. (#14169)
Fixed

Fixes an issue where newly created note annotations would require two taps for deselection. (#15221)

2.5.0 - 11 Apr 2018

API

Deprecates PSPDFAnnotationOptionUserCreatedKey. (#14669)
API

Renames PSPDFSignatureHashAlgorithmSHA386 to PSPDFSignatureHashAlgorithmSHA384 which is actually the correct name. (#13932)
API

tryLoadAnnotationsFromFileWithError: has been removed from PSPDFFileAnnotationProvider. Use loadAnnotationsWithError: instead to customize annotation loading. (#14570)
API

Deprecates PSPDFTextBlock.glyphs, PSPDFWord.glyphs, and PSPDFSelectionState.selectedGlyphs in favor of NSRange-based APIs. (#14606)
API

Adds isGenerated to PSPDFGlyph to check if the glyph is an autogenerated filler. (#14606)
API

PSPDFGlyph.indexOnPage is not -1 to indicate that it is a generated filler. Use PSPDFGlyph.isGenerated instead. indexOnPage can now be used to uniquely identify a glyph on a page, and is the index of the glyph in the PSPDFTextParser.glyphs array. (#14606)
Added

Adds createdAt, updatedAt and creatorName to Instant JSON. (#14443)
Added

Adds isReply and inReplyToAnnotation properties on PSPDFAnnotation. (#5721)

Changed

Removing an annotation with removeAnnotations:options: on PSPDFAnnotationManager or PSPDFDocument now also removes replies to that annotation. (#14385)
Changed

The relationship between PSPDFXFDFAnnotationProvider and PSPDFFileAnnotationProvider is now more explicit. If you use XFDF for form filling, you now need to keep around both providers. Furthermore, the annotation manager now only saves into the first annotation provider implementing the save method. Previously all were called, which could have led to incorrect results. (#14323)
Fixed

Fixes a crash that could happen during application termination. (#14483)
Fixed
