The Instabug SDK for iOS provides a customizable feedback system that can be tailored to fit the needs of each application. The SDK allows developers to choose from various invocation methods, such as shaking the device or tapping on a floating button, and customize prompt options, UI elements, and welcome messages to match their app's brand and style. Additionally, users' data can be customized, including email addresses, attributes, and locales, and network requests can be filtered or hidden. The SDK also provides features like custom categories, logging, and integration with other tools like Jira, Slack, Trello, and Zendesk. By using the Instabug SDK, mobile teams can accelerate their workflows and release with confidence through real-time contextual insights across the entire app lifecycle.
