Or refresh a table view to see changes or perform some user action that forces a redisplay. To have effect, the new code needs to be actually executed and it's up to the user to useĮither an func injected() method or a notification to reload a view controller Users is: I injected a new version of the code, why can't I see the changes on the screen? Is performed on the main thread and generally reliable. Properties or methods on the fly but apart from that exchanging method implementations You can't inject changes to the way data is laid out in memory by adding To reason about your app while you are using injection, separate data and program Inject methods in a private extension as the symbols are not exported To your project or due to details of how a method is dispatched you mayįind InjectionIII half works for classes and classes and not for structs.Īlso, go easy on access control. The iOSInjection.bundle is only loaded duringĭevelopment in the simulator and cannot affect your application when it is deployedĪlways remember to add "Other Linker Flags", "-Xlinker -interposable" Gaining trust in the changes you can inject builds with experience and Keep in mind though the worst case is that yourĪpplication might crash during debugging and you'll have to restart it as you would have For example, it's best not to try to inject aįile containing a protocol definition. Said, you can't just inject any source file. It relies on documentedįeatures of Apple's dynamic linker which have proven to be reliable for over a year now. Managing Expectationsīy rights, InjectionIII shouldn't work and this seems to be a common perception for those who haven't actually tried it and yet it does. To understand how InjectionIII works and the techniques it uses consult the book Swift Secrets. Works for Swift, Objective-C and since 3.2.2 C++ and can be used alongside AppCode or by using the AppCode Plugin InjectionIII.app needs an Xcode 10.2 or greater at the path /Applications/Xcode.app , Target a simulator older than iOS 14 or if you have upgraded to You should use one of these releases for Apple Silicon and want to Releases of the InjectionIII.app available on github. This README includes descriptions of some newer features that are only available in more recent Project watching for file changes in your home directory and using the The "standalone" implementation of injection from the HotReloading If the InjectionIII.app is not running, the bundle will fall back to using ![]() The "injection bundles" from your client app as described below.
