Listing 1 demonstrates how applications can find the AVAudioSessionPortDescription that represents the built-in microphone, locate the front microphone (on iPhone 5 or another device that has a front facing microphone), set the front microphone as the preferred data source and set the built-in microphone port as the preferred input. Once I launch the app with none exterior mics hooked up and provoke the AVAudioSession Ive the identical log as Ive on iOS 16: Then I connect the iRig system (which is mainly the exterior microphone) and Ive the next log: As you see, the enter of the route matches the popular enter of the AVAudioSession. Xcode 9 Swift Language Version (SWIFT_VERSION). In iOS 15 and earlier iOS automatically change the input of the route to any external microphone you attach to the iOS device. var inputDataSource: AVAudioSessionDataSourceDescription?

Add a & character before the variable to make it a pointer: Note: in Swift you don't have to use the method's first parameter's name. When an application sets a preferred value, it will not take effect until the audio session has been activated. Retrieves the preferred number of output channels. Weakly typed; Requests a change to the Category. Using APIs introduced in iOS 7, developers can perform tasks such as locating a port description that represents the built-in microphone, locating specific microphones like the "front", "back" or "bottom", setting your choice of microphone as the preferred data source, setting the built-in microphone port as the preferred input and even selecting a preferred microphone polar pattern if the hardware supports it. Moreover, selecting a Bluetooth HFP output using the MPVolumeView's route picker should automatically change the input to the Bluetooth HFP input corresponding with that output.
