I am developing application for tvOS in swift using Xcode 7.3, I had written a Class to split events on the basis of my requirements like -
import UIKit
class SplitEvents: NSObject
{
var eventDisplayArray:NSMutableArray = []
var eventHiddenArray:NSMutableArray = []
var lastMemorisedDate:NSDate?
var tempEventStartDateEndDateArray:NSMutableArray?
func InitialiseFunction (displayArray:NSMutableArray, HiddenArray hiddenArray:NSMutableArray, ResultArray result:NSArray, completionHandler:(NSMutableArray?,NSMutableArray?, NSError?)->Void?) ->Void
{
eventDisplayArray = displayArray
eventHiddenArray = hiddenArray
SplitEvent(result.mutableCopy() as! NSMutableArray)
completionHandler(eventDisplayArray,eventHiddenArray, nil)
}
func SplitEvent(result:NSMutableArray)->Void
{
if(eventDisplayArray.count>0)
{
for event in result
{
for existingEvent in eventDisplayArray
{
if ((existingEvent as! Event).eventID == (event as! Event) .eventID)
{
result.removeObject(event)
break
}
}
}
}
for event in result
{
tempEventStartDateEndDateArray = []
for dict in (event as! Event).eventSatrtEndDateRange
{
tempEventStartDateEndDateArray!.addObject(dict)
}
if (tempEventStartDateEndDateArray!.count>1)
{
event.eventSatrtEndDateRange.removeAllObjects()
var tempStartEndDateArray:NSMutableArray = []
var i:Int = 0
for fisrtDict in tempEventStartDateEndDateArray!
{
let df = NSDateFormatter()
df.dateFormat = "yyyy-MM-dd"
if ((fisrtDict["start"] as! NSDate) == (fisrtDict["end"] as! NSDate))
{
tempStartEndDateArray.addObject(fisrtDict)
var currentDate:NSDate = fisrtDict["start"]

when i am including above file in my application Xcode giving me compile time error an internal error occurred . Source editor functionality is limited . Attempting to restore...
回答1:
after step by step reviewing of my code finally i figured out issues in my code. If you have more syntax mistakes in your code the swift 2.x Xcode compile stops showing the syntax mistakes & gives the error an internal error occurred . Source editor functionality is limited . Attempting to restore...
The corrected formatting of code is -
