问题 I already experienced this issue in the past, I fixed it. But today I just download the new Xcode version 9.1 and my App is not building anymore, I got : Ambiguous reference to member 'filter' I don't know why, this is not the piece of code I was working on. The app is building/compiling fine since weeks. When I check the Release Note on the Official Apple Website, I don't seem to find any reference to my issue. So here is the piece of code that was working perfectly 2 hours ago : var

问题 I have already change toolchain to swift 2.3 by export PATH=/Applications/Xcode-beta.app/Contents/Developer/Toolchains/Swift_2.3.xctoolchain/usr/bin:"${PATH}" And did Open the Xcode project -> Click on the Realm project -> RealmSwift target -> 'Build Settings' tab -> set Use Legacy Swift Language Version to Yes (if building for Swift 2.3) or No (if building for Swift 3). as Build realm for Swift 3 & Xcode 8 says.

问题 Scenario : Shared/Sync'd Realm. iOS/Swift App with multiple views. What is the best practice design pattern I should use to in order to maintain synchronisation in the background - and - provide automatic (real time) updates to multiple views?

问题 The Situation I've been banging my head on this one for awhile. I have a local DB using Realm with a back end SQL Server DB.

问题 I have a table for favourites and what I want to do is to clear the table of all data and then reload it with the contents of an array. Here is the code: //empty FavouritesRealm table and reload favouritesArray back into FavouritesRealm let clearTable = realm.objects(FavouritesRealm) try! realm.write{ for row in clearTable{ realm.delete(row) } for f in favouritesArray{ let favouriteRealm = FavouritesRealm() favouriteRealm.name = f.name favouriteRealm.price = f.price favouriteRealm.dbSource =
