It looks like we can not convert an empty var array in Swift into NSMutableArray in Objective-C.
var adultTravelerModels: [TravelerDataModel] = []
BookDataManger.sharedInstance().arraySelectedAdultPassenager = adultTravelerModels as! NSMutableArray
/* (lldb) po adultTravelerModels
0 elements */
The system version is iOS 11.0, Xcode 9.0.
How can we solve this?
Do like this:
BookDataManger.sharedInstance().arraySelectedAdultPassenager = NSMutableArray(array: adultTravelerModels)
In Swift 4, you can not assign swift empty array to NSMutableArray.
But you can construct new NSMutableArray and assign to where required.
Like below:
BookDataManger.sharedInstance().arraySelectedAdultPassenager = NSMutableArray(array: adultTravelerModels)
