NSRegularExpression issue

[ZZhaiDev]

Hi, guys
The app is using navigation v0.14.1 or v0.15
I have a HongKong user reporting this "The app will show the navigation screen briefly (half a second) then the app crashed every time", but I can not reproduce this bug.

I can see the crash in my crashlytics:

Fatal Exception: NSInvalidArgumentException
*** -[NSRegularExpression enumerateMatchesInString:options:range:usingBlock:]: nil argument

also this:

Do you guys have any clue what is going on here?

Unfortunately, that isn’t very much information to go off. This library doesn’t use NSRegularExpression, but MapboxDirections.swift does when cleaning up road names in the Directions API response. It would help a lot to know if a particular road is causing this crash. In OpenStreetMap, most Hong Kong street names are bilingual; perhaps some street name has characters that are causing the regular expression to crash for some reason.

The only other thing I can think of is that some of the road name abbreviation functionality may have indirectly used a regular expression. If that’s the case, try upgrading to v0.16.0 or newer, since #1169 removed that functionality in favor of road names preabbreviated by the Directions API.

@1ec5 Thanks, it solved the crash after i release the app with V0.16.2 SDK.
