i'm caching data in coredata within app reduce updating request when there's nothing new. here's caching logic in pseudo code: if cacheexistsincoredata { if cacheisoutdated { loaddatafromremoteandcacheitwithcurrentdate() }else { usecache() }else { loaddatafromremoteandcacheitwithcurrentdate() } how check if cache outdated: func checkifcacheisoutdated { if lastcacheddate isorderthan selfdefinedcheckingdate { return true // need load new data }else { return false // use cache } } this mechanism works fine time. while in rare situation find program caches wrong data right date, means user might see older data , not update when new 1 available. if there's nothing wrong caching logic, wonder if reason when remote data fetched app before gets updated , gets stored in core data latest date time. a cache in core data includes: data(provided remote server) //nothing can it... date(provided me using nsdate()) how can

just looking thought on below branching strategies keeping cicd in mind. master branch - 1.1 development branch - fork master team branch - fork development branch , merge development branch after feature implementation qa/integration testing team b branch - same above 1.1.1 release branch - goes in prod once team , team b branch merge , qa verification done, create release branch , have final regression on it. release branch go production. then merge release master branch. intent - master branch stable , production running code available in it. team branch can deployed on dev environment , have required cicd configuration on server. any issue approach? to being doing ci (and ci required cd) merge master regularly , not have long lived feature branches. believe once day expected "ci". an alternative approach 1 suggest have short lived developer branches daily wo
