Now, perform the same steps to the Widget Extension target. Now that you’ve added App Groups to the capabilities, click the + button to create an app group. Remember this as you’ll need again momentarily.Ĭlick + Capability. Open the Signing & Capabilities tab.Ĭhange the Bundle Identifier to something unique to you such as. Select the NinjaCounter project in the Project navigator to show the Project Editor. To solve this, you’ll add the app and widget to an app group. That’s because the extensions don’t have access to the app’s UserDefaults. Build and run.Ĭurrently, the widget doesn’t show any data, even though you just recorded Leonardo. In getTimeline(in:completion:), the widget uses UserDefaultsHelper‘s getRecordsCount() and getRecords() to get the data from UserDefaults. It creates a simple widget that shows the number of hatchlings counted and the tag of the last hatchling reported. Open Widget.swift and take a look at the code. Now that you get the gist of the starter project, you’ll set up the app widget. With that, you created a new record with the hatchling tag and hatch time. UserDefaultsHelper: A UserDefaults helper that provides methods to store and load hatchling records.īuild and run.Hatchling: A simple struct that has the hatchling record attributes.In the NinjaCounter group, you’ll find the following: The app has one view: CounterView.swift, where users record the hatchlings. The app you’ll work on, NinjaCounter, helps biologists and enthusiasts count turtle hatchlings. Manage build settings across multiple environments and targets.ĭownload the starter project by clicking the Download Materials button at the top or bottom of the tutorial.Work with Xcode build configuration files.Fortunately, Apple has provided a much better way to work with these settings: Xcode build configuration files, or. Managing these settings across different environments in Xcode is time-consuming - not to mention the added work when you have multiple targets. Customers use the app with the final production settings. Testers test beta builds with production-like settings. Developers build an app with debug back-end URLs and settings. In each phase, the app has different build settings, definitions and constants. Warn about implicit conversions of constant values that cause the constant value to change, either through a loss of precision, or entirely in its meaning.Debug, test, release - these are the phases most apps go through. In each case I have included the detailed description from the help documentation for reference. What follows is a more detailed description of each of the four new Xcode 4.6 compiler warning build settings. Anyway since I would probably like to know about suspiciously empty loop bodies I have also enabled it for the existing project. It does seem strange though that the validate settings option does not update it for existing projects. It is possible this was already a default for new projects prior to Xcode 4.6 and I have never noticed. There seems to be one additional compiler warning that is enabled by default for the new Xcode 4.6 project that the validate settings option does not enable for existing projects:Įmpty Loop Bodies: Warn about loop bodies that are suspiciously empty. Out of curiosity I compared the build settings after updating this project with a clean new project created with Xcode 4.6. From the date I would guess that means I was probably using Xcode 4.3.3. The remaining setting is in the Apple LLVM compiler 4.2 - Warnings - Objective C section:Ī useful tip here to get a detailed description for a build setting is to have the quick help window open in the utilities sidebar when clicking on each setting.įor the purposes of this post I have been using one of the example projects (WorldFacts) from my GitHub CodeExamples repository which was created back in June 2012. If you check the build settings for the project you will find three of the new settings in the Apple LLVM compiler 4.2 - Warnings - All languages section: CLANG_WARN_CONSTANT_CONVERSION = YES CLANG_WARN_ENUM_CONVERSION = YES CLANG_WARN_INT_CONVERSION = YES CLANG_WARN_DUPLICATE_METHOD_MATCH = YES
