-
Network Connectivity Issues
Network connectivity is inherently unreliable, and code must account for potential interruptions during data transmission. Effective error handling includes detecting network unavailability, managing connection timeouts, and implementing retry mechanisms. For example, an application downloading a large file should be able to pause and resume the download when network connectivity is restored. Without such handling, the download may fail, requiring the user to restart the process. Such scenarios degrade the user experience and reduce the application’s reliability.
-
Data Validation and Format Errors
Data received from external sources may not always conform to expected formats or data types. Code must validate incoming data to prevent processing errors and potential security vulnerabilities. Error handling involves detecting invalid data, providing informative error messages, and implementing fallback mechanisms. An application receiving JSON data from a server should validate that the data conforms to the expected schema. If validation fails, the application should reject the data and display an appropriate error message. Failure to validate input can lead to application crashes or, in severe cases, security breaches.
-
Storage Access Failures
Storing or retrieving data from the device’s storage system can encounter various errors, such as insufficient storage space or file access permission issues. Code must handle these errors gracefully, providing clear feedback to the user and preventing data loss. An application saving an image to the photo library should check for available storage space and request appropriate permissions from the user. If the operation fails, the application should display an informative error message rather than silently failing. Poor error handling in storage operations can lead to data corruption or loss of user-generated content.
-
API and Framework Exceptions
iOS frameworks and APIs can raise exceptions due to various reasons, such as incorrect usage or system limitations. Code must catch and handle these exceptions to prevent application crashes. Exception handling involves wrapping potentially problematic code in try-catch blocks and implementing appropriate error recovery strategies.
