YouTube Native Share

iOS Tweak to bypass YouTubes own share sheet and use the system activity view instead. Avoids requesting a source identifier (si) with your data and sharing it with other people. Compatible with all YouTube versions ≥ 17.32.2.

Why

YouTubes share sheet sucks. It isn't customizable and uses a pre-defined set of URL handlers to check for commonly installed apps (e.g. WhatsApp, Snapchat, Facebook) and then displays those whose URL can be successfully opened:

[...]
+|NSURL URLWithString:| @"twitter://://"
-|UIApplication@<0xc90e41c90> canOpenURL:| <NSURL@0x2839eaf00>
[...]
+|NSURL URLWithString:| @"fb-messenger://://"
-|UIApplication@<0xc90e41c90> canOpenURL:| <NSURL@0x2839ece00>
[...]
+|NSURL URLWithString:| @"fb://://"
-|UIApplication@<0xc90e41c90> canOpenURL:| <NSURL@0x2839ed880>
[...]
+|NSURL URLWithString:| @"whatsapp://send://"
-|UIApplication@<0xc90e41c90> canOpenURL:| <NSURL@0x2839ecc00>
[...]

Furthermore, before displaying the share sheet, the app requests a source identifier (si), that will be appended to the share URL, e.g. https://youtu.be/dQw4w9WgXcQ?si=ABCDEFGHIJKLMNOP. This allows YouTube to link other users to you if they click on the share URL, which improves their tracking. This is the data the source identifier is requested with:

Aside the tracking, this also makes it impossible to share anything without an internet connection, as the source identifier cannot be requested in this case (I didn't test downloaded offline videos, maybe the source identifier is requested in advance or ommitted here).

What

This small tweak skips sending the YTIGetSharePanelRequest and allows you to share links without a source identifier (si). YouTube most definitely receives all of the information contained in a YTIGetSharePanelRequest through other requests anyway - you'd have to stop using YouTube to avoid this - but sharing links without source identifiers will make it at least a bit harder for YouTube to create links between users.

Finally, it also replaces YouTubes own share sheet by the system share sheet:

Special Thanks

Thanks to iCraze for developing YTStockShare, which inspired me to develop a similar tweak for newer YouTube versions.

Thanks to the developers of FLEX and InspectiveC, which both really helped during development of this tweak.
