[SOLVED] Get build date and time in Swift

Issue

I’m using __DATE__ and __TIME__ in Objective-C to get the build date and time of my app. I can’t find a way to get this information in Swift. Is it possible?

Solution

You can use #line, #column, and #function.

Original answer:

Create a new Objective-C file in your project, and when Xcode asks, say yes to creating the bridging header.

In this new Objective-C file, add the following the the .h file:

NSString *compileDate();
NSString *compileTime();

And in the .m implement these functions:

NSString *compileDate() {
    return [NSString stringWithUTF8String:__DATE__];
}

NSString *compileTime() {
    return [NSString stringWithUTF8String:__TIME__];
}

Now go to the bridging header and import the .h we created.

Now back to any of your Swift files:

println(compileDate() + ", " + compileTime())
