Log Swift Reference Documentation
CkoLog
Current Version: 10.1.0
Handy logging class exposing much of the functionality used internally by Chilkat for LastErrorText, LastErrorXml, and LastErrorHtml.
Object Creation
let obj = CkoLog()!
Properties
DebugLogFilePath
If set to a file path, this property logs the LastErrorText of each Chilkat method or property call to the specified file. This logging helps identify the context and history of Chilkat calls leading up to any crash or hang, aiding in debugging.
Enabling the VerboseLogging property provides more detailed information. This property is mainly used for debugging rare instances where a Chilkat method call causes a hang or crash, which should generally not happen.
Possible causes of hangs include:
- A timeout property set to 0, indicating an infinite timeout.
- A hang occurring within an event callback in the application code.
- An internal bug in the Chilkat code causing the hang.
LastErrorHtml
Provides HTML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastErrorText
Provides plain text information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
LastErrorXml
Provides XML-formatted information about the last called method or property. If a method call fails or behaves unexpectedly, check this property for details. Note that information is available regardless of the method call's success.
topLastMethodSuccess
Indicates the success or failure of the most recent method call: true means success, false means failure. This property remains unchanged by property setters or getters. This method is present to address challenges in checking for null or Nothing returns in certain programming languages.
topVerboseLogging
If set to true, then the contents of LastErrorText (or LastErrorXml, or LastErrorHtml) may contain more verbose information. The default value is false. Verbose logging should only be used for debugging. The potentially large quantity of logged information may adversely affect peformance.

Methods
Clear
Clears the log. The initialTag is the initial top-level context tag for the new log.
topEnterContext
Enters a new context labelled with the given tag. Must be paired with a matching call to LeaveContext.
LeaveContext
Leaves the current context. A context that is entered and exited without any logging within the context is automatically removed from the log. (To say it another way: Empty contexts are automaticallly removed from the log upon leaving the context.)
topLogData
Adds a tagged message to the log (i.e. a name/value pair).
topLogDataBase64
Logs binary data in base64 format.
topLogDataHex
Logs binary data in hex format.
topLogDataMax
Logs a string, but only up to the 1st maxNumChars characters of the string.
topLogDateTime
Logs the current date/time in RFC822 format. If gmt is true, then the GMT/UTC time is logged. Otherwise it is the local time.
topLogError
Logs an error within the current context.
topLogInfo
Logs an informational message within the current context.
topLogInt
Logs an integer.
topLogInt64
Logs a 64-bit integer.
topLogTimestamp
Logs the current time in HH:MM:SS:mmm format.
