Disabling print for Production In Swift Project


You'll need to set up a compiler flag to use the Swift preprocessor - go to the Swift Compiler - Custom Flags section of Build Settings to set up a -D DEBUG flag:




Then in your code you can define a DLog() function and only print your message if the DEBUG flag is set:

func DLog(message: String, function: String = __FUNCTION__) {
    #if DEBUG
    println("\(function): \(message)")
    #endif
}

    Pan cards are intended for citizens and business elements, trusts, affiliations etc. As this is a Government process, quoting a time is very difficult. However it does not take more than 15-20 days to receive a pan card at an worldwide location from the date of submitting an application to the appreciated processing authority. There have been instances when this stipulated time can be less or may be more than 15 days. There are two ways to apply for PAN Card : 1. Online, 2. Offline. Online : You can apply for PAN card online at any of the given websites. Offline : I don’t have much knowledge for applying PAN Card this way.While, online process is the best process. We can view its status at each and every moment. Ref : apply here

How to kill/exit iOS application on a button click programmatically

I had been practising below code to kill an iOS application. exit(0); But last week, my application was rejected by app store due to following reason: We found that your app includes a UI control for quitting the app. This is not in compliance with the iOS Human Interface Guidelines, as required by the App Store Review Guidelines . To avoid any such rebuff, suspend the application using following code snippet. UIApplication.shared.perform(#selector(NSXPCConnection.suspend)) Good news is that now my application is passed the  iOS Human Interface Guidelines and live on app store.

Return multiple values from a function in objective C

We can return tuples in swift as follows:- func getData () -> ( Int , Int , Int ) { //...code here return ( hour , minute , second ) } You can't do that in objective-c. Best option is using parameters by reference . Something like this. - ( void ) getHour :( int *) hour minute :( int *) minute second :( int *) second { * hour = 1 ; * minute = 2 ; * second = 3 ; } And use it like this. int a , b , c ; [ self getHour :& a minute :& b second :& c ]; NSLog (@ "%i, %i, %i" , a , b , c );
