Thank you, Matthew York and community for awesome library. You can find original repo/docs here. This package was created because I need Carthage support and distinguish between Swift and Objective-C implementation. Swift ABI not stable (yet) and I do not want to spend time to recompile binaries every time new Swift version come. Objective-C API works perfectly fine.

This is hard fork of original repo. This means there is no guarantee that codebase will fully reflect original repo.

• DateTools removes the boilerplate required to access date components, handles more nuanced date comparisons, and serves as the foundation for entirely new concepts like Time Periods and their collections.

How to check if two date ranges overlaps in Objective-C? With DateTools it’s really easy.

// Just example.
DTTimePeriod *periodA = [[DTTimePeriod alloc] initWithStartDate:request.startDate endDate:request.endDate];
DTTimePeriod *periodB = [[DTTimePeriod alloc] initWithStartDate:requestB.startDate endDate:requestB.endDate];
//Magic here
if ([periodA overlapsWith:periodB]) {
    NSLog(@"Is it cool?");
}

Use with Swift Package Manager

.package(url: "https://github.com/3a4oT/DateToolsObjC", .upToNextMajor(from: "1.0.5"))

How to use with Carthage:

• Add to your Cartfile github "3a4oT/DateToolsObjC"
• Run carthage build 3a4oT/DateToolsObjC
• Add DateToolsObjC.framework to your target
• In your *.h/*.m just @import DateToolsObjC;

Can I use it from Swift?

Well, technically yes. But…=) it will work for NSDate and not for Date out the box. You will ask why? Shorty - NSDate and Date are two different types (some more food). Don’t be confused about other thing you may hear that’s different. So far you have 3 option to go with

1. Checkout original repo and use Swift API.

2. Cast Date to NSDate and back:

      import DateToolsObjC
      let today: NSDate = Date() as NSDate
      //usage in DateToolsAPI return NSDate cast back if you need.
      let result: Date = today.timeAgo() as Date

3. My favorite - just make Swift Extension under needed DateToolsObjC API which will cast NSDate to Date for you.
