Does it detect hashtags in arabic letters?

[keegho]

I have an issue that every time i tap on an arabic hashtag the app crashes in the AppDelegate.swift
After adding some break points in the shouldInteractWith URL function it doesn't even run the function. Very weird.
Any information if these links could be in arabic language and this would crash the app or the crash i have is due to something totally different? I tried to search every where over the internet but i didn't get any useful information.

I haven't tested this in any other languages. And it's been a while since I've done any Swift, so I probably won't get around to fixing this issue. But you might want to try debugging resolveHashTags(). Either that, or see if you can inspect the text view's attributedText to see it's what you're expecting.

@chenr2 thanks for the fast reply. I did inspected and printed out the detected arabic text on the console. And the text is in blue color and considered as a link but when i tap on it it crashes.

I'm a little rusty... but is the UITextView delegate set to the ViewController?

Yes and english hashtags are working fine.

I'm sort of at a loss. The only thing I can think of would be to try caveman debugging every line of resolveHashTags(). In that function, I delimit the string by a single space character, and iterate over each word. There isn't any consideration for other languages, right-to-left text, etc. So it's possible that ranges could be out of index as it tries to apply link attributes.

Thanks @chenr2 i resolved the issue. The issue is that the UITextViewDelegate function is not called because the arabic letters stringified word is returning NIL as a URL. So needed to add percentEncoding to the stringified word.

// drop the hashtag stringifiedWord = dropFirst(stringifiedWord).addingPercentEncoding(withAllowedCharacters: .urlHostAllowed)

Good work @keegho! Thanks for figuring that out.
