The following always returns nil on all iPhone 11 simulators but works fine on devices and simulators prior to 11.
let containerURL = fileManager.containerURL(forSecurityApplicationGroupIdentifier: "group.my.group.name.here")
Anyone else encounter this? What is the solution?
After a whole day of debugging, I think I might have found a workaround.
I think it has to do with the Bundle Identifier. So if you have a bundle identifier xx, it fails, but it works if your bundle identifier is xx.xx
So for example it fails with Bundle Identifier: musicapp
It will work with the Bundle Identifier: com.steventso.musicapp or even com.musicapp
Since you can't change the Bundle Identifier after you've released the app to the public, the workaround is to create a new Target that you use strictly for development and when using the simulator where it is under a bundle identifier with the naming scheme xx.xx
Yeah it's a strange bug I hope they fix, but I think I was wrong in even naming it with the scheme of xx in the first place.
It's hard to tell if this will break iPhone X since there is no physical device to test on, so fingers cross this works out okay.
