"Reading from public effective user settings" in iOS 10
IosSwiftIos10Ios Problem Overview
I'm getting the following messages when launching my app:
2016-10-12 14:47:23.705002 Discovery[377:147958] [MC] System group container for systemgroup.com.apple.configurationprofiles path is /private/var/containers/Shared/SystemGroup/systemgroup.com.apple.configurationprofiles
2016-10-12 14:47:23.712212 Discovery[377:147958] [MC] Reading from public effective user settings.
Is "system group container" related to App Groups? I do share data between apps using an App Group and was wondering if this caused this message to be displayed?
I set the data in one app like this:
var userDefaults = NSUserDefaults(suiteName: "group.com.company.myApp")
userDefaults!.setObject("user12345", forKey: "userId")
userDefaults!.synchronize()
And I retrieve it in another app using something like this:
var userDefaults = NSUserDefaults(suiteName: "group.com.company.myApp")
if let testUserId = userDefaults?.objectForKey("userId") as? String {
print("User Id: \(testUserId)")
}
Did something change in iOS 10 that would cause any problems or cause these messages to show up?

This is a bug (now we're finding out it might be a permanent message) and it seems that this message appears primarily when clicking on a Text Field or Text View or other similar NSObject.
This is only a log message and not a compile error message as signified by the date and time preceding the message. Therefore if your code is not working it is not a result of this console message.
If you run on a device the message will be [MC] Reading from public effective user settings
. If you run on the sim the message will be [MC] Reading from private effective user settings
.

I had this same problem when touching a Bar button that showed an alert, which in turn has a TextField. Any way I solved this matter using the proposal commented in this link. It works at least for me! regards!

I was struggling with this issue in an iPhone5 emulator (on the device everything was ok) that stucked my Ionic app after touch a TextInput, and then I changed the emulator to another one, like iPhone6, or iPhone8, and everything worked again.
