cocoa touch - Can anyone recommend an open-source up-to-date actively developed basic AR library for iOS? -

the issue i'm having can't find actively developed open-source ar library ios.

i don't need 3d support or maker based recognition. ability place icons/labels yelp's famous monocle feature.

my goal integrate ar app users can view poi's near location. app has map view doing , thought cool use ar view too.

i've looked at:

• mixare (ios version not smooth, buggy, , code chaotic. not seem supported anymore, there's not been update 5 months).
• arkit (not been updated in 4 years , has warning being bit rough).

anyone had experience or know of round library can drop application?

alternatively if can recommend books or tutorials on how write own appreciated.

for simple integration can use junaio plugin or wikitude sdk. not open-source solution sufficient if not interested modify layout, representation or internal computation transforming pois ar view.

there example gps-based ar professional ios programming book available github, panicar (just search on github.com).

finally apples provides basic implementation in ios developer library: park.
