Specifies the TBD file version. The only supported version is 5.

Specifies the linkage properties of the main dylib in the TBD.

Specifies the supported targets of the dylib per target slice.

Specify the architecture and platform identifier supported by the dylib. Those identifiers are mapped to the platform number that is specified by the Mach-O format for the LC_BUILD_VERSION load command. It is also possible to encode the platform with the platform number directly (for example: x86_64-maccatalyst).
The following platform identifiers are supported: macos, maccatalyst, ios, ios-simulator, tvos, tvos-simulator, watchos, watchos-simulator.

Specify the minimum deployment version to match the target for the dylib. This key is part of the LC_BUILD_VERSION load command.

Specifies the install name of the dylib per target slice. This key is part of the LC_ID_DYLIB load command in the Mach-O format. If targets section is omitted, the install name is the same for all targets recorded in target_info.

Specifies the flags of the dylib per target slice. If targets section is omitted, the flags are the same for all targets recorded in target_info.
Valid flags are: flat_namespace and not_app_extension_safe. flat_namespace is deprecated, but there are still some old binaries around on macOS that depend on flat namespace linking. The default is two level namespace linking. not_app_extension_safe indicates that the library is not safe to be used in an Application Extension.

Specifies the current version of the dylib per target slice. This key is part of the LC_ID_DYLIB load command in the Mach-O format. If targets section is omitted, the current version is the same for all targets recorded in target_info. The default value is 1.0 if not specified.

Specifies the compatibility version of the dylib per target slice. This key is part of the LC_ID_DYLIB load command in the Mach-O format. If targets section is omitted, the compatibility version is the same for all targets recorded in target_info. The default value is 1.0 if not specified.

Specifies the Swift ABI version the dylib was compiled with per target slice. The Swift ABI version is encoded in the Objective-C image section, which doesn't exist in stubbed dynamic library files. If targets section is omitted, the compatibility version is the same for all targets recorded in target_info. The default value is 0 if not specified.

Specifies the parent umbrella of the dylib per target slice. This key is equivalent to the LC_SUB_FRAMEWORK load command in the Mach-O format. If targets section is omitted, the parent umbrella is the same for all targets recorded in target_info.

Specifies the list of re-exported libraries of the dylib per target slice. This key is equivalent to the LC_REEXPORT_DYLIB load command in the Mach-O format. If targets section is omitted, the list of re-exported libraries are the same for all targets recorded in target_info.

Specifies the list of runpath search paths of the dylib per target slice. This key is equivalent to the LC_RPATH load command in the Mach-O format. If targets section is omitted, the list of runpath search paths are the same for all targets recorded in target_info.

Specifies the regular export symbol sections. If targets section is omitted, the exports are the same for all targets recorded in target_info.

Specifies the export symbol sections, but these symbols are not defined by the library itself. Instead, these symbols come from a different library. If targets section is omitted, the re-exports are the same for all targets recorded in target_info.

Specifies the undefined symbol sections and are only used for flat address space libraries. If targets section is omitted, the undefineds are the same for all targets recorded in target_info.

Specifies the symbols defined in __TEXT segment of the library.

Specifies the symbols defined in __DATA segment of the library.

Specifies the a list of exported, re-exported, or undefined symbol names.

Specifies the names of weak defined symbols for exported symbol sections or weak referenced symbols for undefined symbol sections.

Specifies the symbol name of thread local exports.

Specifies the list of exported, re-exported, or undefined Objective-C class names.

Specifies the list of exported, re-exported or undefined Objective-C class exception type names.

Specifies the list of exported, re-exported or undefined Objective-C instance variable names.

Specifies the inlined tbd attributes for the main_library's reexported libraries.
