API differences

  • Customizing annotation permissions has changed. The new APIs are cleaner and easier to write as they employ properties with full code completion, vs. text strings that required consulting documentation. For example:

Version 6.9.3+ (new method):

toolManager.inkAnnotationPermission.canCreate = false
toolManager.inkAnnotationPermission.canEdit = false
toolManager.highlightAnnotationPermission.canCreate = false
toolManager.highlightAnnotationPermission.canEdit = false

Version 6.8.7-6.9.2 (previous method):

toolManager.configure(with: ToolManagerConfiguration { builder in
    builder.annotPermissions = [
        .ink : [
            .canCreate : false,
            .canEdit : false,
        .highlight: [
            .canCreate: false,
            .canEdit: false,
  • An API diff from the previous version is available.
