A simple Swift wrapper around an Objective-C @try/@catch statement that selectively catches Objective-C exceptions by NSException subtype, rethrowing if any caught exception is not the expected subtype.

Look at CwlCatchExceptionTests.swift for syntax.

This project can be used by direct inclusion in your projects or through any of the Swift Package Manager, CocoaPods or Carthage.

Minimum requirements are iOS 8 or macOS 10.9.

1. In a subdirectory of your project's directory, run git clone https://github.com/mattgallagher/CwlCatchException.git
2. Drag the "CwlCatchException.xcodeproj" file from the Finder into your own project's file tree in Xcode
3. Add the "CwlCatchException.framework" from the "Products" folder of the CwlCatchException project's file tree to the "Copy Files (Frameworks)" build phases of any target that you want to include this module.

That third step is a little tricky if you're unfamiliar with Xcode but it involves:

a. click on your project in the file tree b. click on the target to whih you want to add this module c. select the "Build Phases" tab d. if you don't already have a "Copy File" build phase with a "Destination: Frameworks", add one using the "+" button in the top left of the tab e. click the "+" within the "Copy File (Frameworks)" phase and from the list that appears, select the "CwlCatchException.framework" (if there are multiple frameworks with the same name, look for the one that appears above the corresponding macOS or iOS CwlCatchException testing target).

Add the following to the dependencies array in your "Package.swift" file:

.Package(url: "https://github.com/mattgallagher/CwlCatchException.git", majorVersion: 1),

Or, if you're using the swift-tools-version:4.0 package manager, add the following to the dependencies array in your "Package.swift" file:

.package(url: "https://github.com/mattgallagher/CwlCatchException.git", majorVersion: 1)

Add the following to your target in your "Podfile":

pod 'CwlCatchException', :git => 'https://github.com/mattgallagher/CwlCatchException.git'

Add the following line to your Cartfile:

git "https://github.com/mattgallagher/CwlCatchException.git" "master"
