ios - iPhone and Apple Watch not sharing App Group -


i've been pulling hair out on problem 2 days now. generate small movie file in iphone app want send iphone play on apple watch. proof of concept, put similar .mov in bundle of apple watch app , able play no problems. figured, easy peasy, when want send new little clip watch, put in app group shared container , access there instead of bundle. nope!

i have been through tons of s.o. posts, tried many different approaches , nothing works expected.

before ask, have re-done app group several times, deleted old ones itunes connect, re-generated provisioning profiles, cleaned targets numerous times, deleted deriveddata several times, deleted apps , started on several times , tried virtually every little tweak , fix find on s.o. nothing helps.

i think know problem is, have no idea how conquer it.

here code use in both iphone app , watch app path shared container (this snippet if watch side):

let filemanager = filemanager.default     let sharedcontainer = filemanager         .containerurl(             forsecurityapplicationgroupidentifier: "group.com.mycompany.myappname")      let dirpath = sharedcontainer?.path      sharedfilepathonwatch = (dirpath! nsstring).appendingpathcomponent("watchpreview.mov")      print ("shared file path on watch: \(sharedfilepathonwatch)")     print ("shared file path iphone: \(sharedfilepath)")

the print statements show me shared file path send on watch iphone (via watch connectivity) , shared path watch app resolves.

what when runs following:

shared file path on watch: /private/var/mobile/containers/shared/appgroup/94aa7797-528d-4e96-9623-23285be0742b/watchpreview.mov

shared file path iphone: /private/var/mobile/containers/shared/appgroup/4d43c314-ccbd-4861-bf90-69a8ac71198c/watchpreview.mov

now expecting there 1 shared container , both iphone , watch should resolve same path, not case. i've noticed these paths remain constant 2 apps on multiple runs. it's not dynamic address changing every time run suspected awhile.

as last ditch attempt function, figured since had path shared container on iphone , shared container on apple watch, maybe move file 1 other because, well, supposed sharing. no, doesn't work.

so big questions are:

  1. why resolve 2 different paths on shared apps
  2. how heck little movie file iphone apple watch

with introduction of watchos2 , native watchos apps, apple watch apps no longer extensions of ios counterpart , hence don't share appgroups.

you cannot use appgroups sharing data watchos2 onwards. have use watchconnectivity framework sending data between ios , watchos apps.

see watchkit programming guide - sharing data page more information on topic.

command line - How can a Python program background itself? -

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
