Managing the Pasteboard

Firebase Dynamic Links 4.2.0 and higher use a plist property FirebaseDeepLinkPasteboardRetrievalEnabled that a developer can set to enable/disable the use of iOS pasteboard by the SDK.

FDL SDK uses the pasteboard for deep-linking post app install (to enable deferred deep-linking, where the link is copied on the app preview page) and app install attribution; otherwise, FDL does not use the pasteboard for anything else.

Disabling pasteboard access affects the app in the following ways:

• Deferred deep-linking will not work as reliably. At best, your app receives weak matches for deep-links.
• App install attribution stats will be less accurate (potentially undercounting app installs).

Enabling pasteboard access affects the app in the following ways:

• On iOS 14, will show a system alert notifying that your app accessed the content in the pasteboard. This should happen one-time after installation of the app.
• Deferred deep-linking will work as designed. At best, your app receives a perfect match for deep-links.
• SDK will be able to more reliably attribute installation stats for links.
