Summary:
In a Swift playground I can retrieve the default instance of NSUserDefaults, but adding values to it has no effect.
Steps to Reproduce:
Create an iOS Swift playground and paste the following code into it:
let standardUserDefaults = NSUserDefaults.standardUserDefaults()
standardUserDefaults.setObject("TestString", forKey: "testKey")
standardUserDefaults.setInteger(10, forKey: "testInt")
standardUserDefaults.synchronize()
let defaultsDictionary = standardUserDefaults.dictionaryRepresentation()
Expected Results:
The dictionary representation should include the added string and integer.
Actual Results:
The NSUserDefaults dictionary representation is the same as initially, and no values have been added.
Version:
Xcode 7.3.1 (7D1014)
Notes:
If this feature is not supported, it must be clearly documented. But I could not find any references to playground in the documentation for NSUserDefaults.
Configuration:
OSX El Capitan, Xcode 7.3.1 (7D1014)
