XLIFFKit

A Swift framework for parsing and modifying XLIFF files.

An example XLIFF file:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<xliff version="1.2">
    <file original="Sample/en.lproj/Localizable.strings" source-language="en" target-language="it">
        <body>
            <trans-unit id="common.greeting.hello" xml:space="preserve">
                <source>Hello</source>
                <target>Ciao</target>
                <note>Casual greeting</note>
            </trans-unit>
            <trans-unit id="How are you?" xml:space="preserve">
                <source>How are you?</source>
                <target>Come stai?</target>
                <note></note>
            </trans-unit>
        </body>
    </file>
    <file original="AnotherSample/en.lproj/Localizable.string" source-language="en" target-language="it">
        <body>
            <trans-unit id="Thank you" xml:space="preserve">
                <source>Thank you</source>
                <target>Grazie</target>
            </trans-unit>
            <trans-unit id="You’re welcome" xml:space="preserve">
                <source>You’re welcome</source>
                <target state="needs-review-translation">Prego</target>
                <note>Casual thanks</note>
            </trans-unit>
            <trans-unit id="How old are you?" xml:space="preserve">
                <source>How old are you?</source>
            </trans-unit>
        </body>
    </file>
</xliff>

Usage

Import the framework:

import XLIFFKit

Opening an XLIFF:

let document = try XLIFFDocument(data: data)

Iterating through the XLIFF's translation units:

for file in document.files {
  for translationUnit in file.body.translationUnits {
    print(translationUnit.source, translationUnit.target)
  }
}

Where a XLIFFTranslationUnit is:

public struct XLIFFTranslationUnit: Hashable {
  public let uuid: UUID
  public let id: String
  public let source: String
  public let note: String?
  public var target: String?
  public var state: XLIFFState?
}

Modifying a translation unit:

let file = document.files[0]
var translationUnit = file.body.translationUnits[0]

translationUnit.target = "New value"
translationUnit.state = .needsReviewTranslation

document.updateTranslationUnit(forFileUUID: file.uuid, to: translationUnit)

The UUID is not present in the XLIFF; one is generated for files and translation units. It is used to refer to and track elements in the document.

After making a modification, document.hasUnsavedChanges will become true. Call document.commitUnsavedChanged() to write the changes back to the underlying XML document.

Saving changes:

if document.hasUnsavedChanges {
  document.commitUnsavedChanges()
}

let newData = document.xmlData()
