Riot iOS fails to linkify some known TLDs

[anoadragon453]

Riot iOS is failing to turn links like maunium.dev into a link. Is there a list of known TLDs somewhere that Riot iOS uses, and if so can we use a regex instead (or does Apple provide an API or this)? As otherwise we'll always be out of date as new TLDs come out.

Message cells use UITextView that can detect automaticaly some data (like links) and convert them to URLs (see UITextView.dataDetectorTypes property documentation for more information). The Apple link detector does not detect every kind of links and unfortunately we can't set a custom data detector to the UITextView.

We have to manually detect custom links. To achieve this we plan to:

• Create our own data detector, to detect URL, Matrix IDs, rooms etc. using custom regexes.
• Parse manually every text message content.
• Detect string to convert to URLs using the detector.
• Always build string to display using NSAttributedString.
• Create a NSAttributedString with NSAttributedString.Key.link attribute when a link is detected.
• Fill the UITextView.attributedText property with the builded NSAttributedString.

Note: Once it's all done it will also be possible to use UILabel instead of UITextView to display links. Handling tap gesture on it will be another subject.
